Home Wireless Network Security Issues
Autor: gllz12
Running a business from home has its advantages, including no commute, a more accommodating work schedule, fresh coffee and home-cooked meals at any time you want.
But running a business from home using a home wireless local area network (WLAN) with your computer may lead to thievery of confidential information and hacker or virus penetration unless proper actions are taken. As WLANs send information back and forth over radio waves, someone with the right type of receiver in your immediate area could be picking up the transmission, thus acquiring access to your computer.
Here is a list of things that you should consider as a result of implementing a home wireless network setup used your business:
Viruses could be loaded onto your laptop which could be transferred to the company's network when you go back to work.
Up to 75 per cent of home wireless network WLAN users do not have standard security features installed, and 20 per cent are left completely open as default configurations and are not secured, but are made for the users to have their network up and running ASAP.
It is recommended that home wireless network router/access point system setups be always done though a wired client.
Always change the default administrative password on your home wireless network router/access points to a secured password.
Enable at least 128-bit WEP encryption on both card and access point. Change your WEP keys periodically. If equipment does not support at least 128-bit WEP encryption, consider replacing it. Although there are security issues with WEP, it represents minimum level of security, and it should be enabled.
Change the default SSID on your router/access point to a hard to guess name. Setup your computer device to connect to this SSID by default.
Setup router/access points so as to not broadcast the SSID. The same SSID needs to be setup on the client side manually. This feature may not be available on all equipment.
Setup your home wireless network router to block anonymous internet requests or pings.
On each computer having a wireless network card, network connection properties should be configured to allow connection to Access Point Networks Only. Computer to computer (peer to peer) connections should not be allowed.
Enable MAC filtering. Deny connection to wireless network for unspecified MAC addresses. MAC or physical addresses are accessible through your computer device wireless network connection setup and they are physically written on network cards. When adding new wireless cards / computer to the network, their MAC addresses should be registered with the router /access point.
Your home wireless network router should have firewall features enabled and demilitarized zone (DMZ) feature disabled. Periodically test your hardware and personal firewalls using Shields Up test available at Gibson Research Corp. web site. All computers should have a properly configured personal firewall in addition to a hardware firewall.
Update router/access point firmware when new versions become available.
Locate router/access points away from strangers so they cannot reset the router/access point to default settings. Also, locate router/access points in the middle of the building rather than near windows to limit signal coverage outside the building.
You should know that nothing is 100%. While none of the actions suggested above will provide full 100% protection, countermeasures do exist that will help. The good collection of suggested preventative actions contained herein can help you deter an intruder trying to access your home wireless network. This deterrant then makes other insecure networks easier targets for the intruder to persue.

Get the Highest Speed Out of Your Wireless Computer Network
Autor: gwalding
When it comes to a wireless standard, the first thing we all look at is how fast will this baby run! And you know the trade-offs, you can spend a lot of money to get the fastest thing running, or you can back off a little and save a lot.
The good thing about wireless networks is that the price difference between wireless standards is almost gone. There are some things that could add up, but I will explain the difference and why you might want to go that route or not.
Now, let's get to the different wireless standards you can choose from.
1. 802.11b - 11Mbit at 2.GHz
2. 802.11a - 54Mbit as 5.0GHz
3. 802.11g - 54Mbit at 2.4GHz
4. Hybrid Systems
When you get ready to purchase your equipment, you will see a lot of systems saying that they are faster than these standards listed above. Most will say 108Mbit per second, some 125Mbit per second and a few even higher. To operate at these speeds usually requires you to only use their network cards to access their access points, some of them require a specific card from them to get that speed. If any other card connects, then they will drop back to the standard speed and you lose the extra speed you probably paid extra to get.
What Should You Get
I was purchasing equipment for a completely new wireless setup. We only had one older wireless computer and I replaced the card in it with a new one. I did purchase a system that advertised the 108Mbit speeds since I knew who was going to connect to it.
If you are building a new network setup, I suggest you purchase a system that will run faster than the standard, but only if you know who is connecting. If not, then get a system that runs on the 802.11g standard. The price is about the same as 802.11b but runs 5 times faster.

The Future Of Wireless Technology
Autor: kensnow
Wireless technology is gaining ground because of its low cost and ease-of-use. We all are familiar with radio and phones that use wireless technology. There are many more possible practical applications for wireless and the breakthrough developments happening in this field are set to revolutionize the future.
Wireless network means less maintenance and less cost. The advent of radio has put a stop to the use of telephones that uses wires to transmit signals. The new age cell phones based on wireless technology have made it possible for us to reach anyone anytime. Wireless technology translates into a lower cost since it obviates the laying down of cables and wires and regular maintenance. The other area where a significant impact has been felt is in the networking of computers. The usual scenario of having a wired Internet connection is all set to change. The wireless connections are soon going to be cheaper than the wired alternative and will also be easier to use. This will result in people shifting to the wireless option, if available.
Worldwide Interoperability for Microwave Access (WiMAX) will be the next generation of wireless, an improvement over the existing wireless networking that uses a standard called 802.11. The good news is that you will not need to change your equipment, as it will run on the existing hardware. Though scientists are still working on it, it is poised to take the world by storm. The first WiMAX equipment is slated for launch by the end of 2005. Its biggest advantage will be that it will cover a wide area, which could be as much as up to 50 kilometers! The term Local Area Network (LAN) will be replaced by Metropolitan Area Network (MAN), which would cover the whole city! It will also offer higher speeds of up to an astounding 10MB per second, coupled with improved security. All you would need to do is buy a subscription, plug into a network and you are ready to go!
Bluetooth technology is becoming a part of our lives now. Apart from replacing your USB port, it has the potential of replacing all the wires in your equipment, except for the power cord! Imagine the convenience of staying in a house that does not have wires, where Bluetooth connects all the equipment. It would mean fewer hassles in cleaning the house coupled with freedom from the fear of tripping over wires!
It wouldn't be surprising if by the end of the next decade wireless technology would becomes commonplace. It sounds convenient and should also be lesser in cost. Given its potential, we all seem to have a much easier life, with a faster and safer access to the world!

Setting Up A Home Network
Autor: marshc01
There is essentially two ways of setting up a home network, wired or wireless.
A wired network involves connecting up the computers using cables, and if often referred to as an Ethernet network. An Ethernet network transfers data at high speeds, faster than wireless networks as it is very rare for the connection to be interrupted. Although data transfer speeds of 1 Gbps can be achieved, the average speed is 100 Mbps, and this is why you will often see "10/100" next to Ethernet ports on computers or in product data specs.
A wireless network transfers data via radio waves and is the preferred, and most often convenient, method of setting up a home network. It is especially useful for the use of laptops as it allows the user to roam throughout the house, and even the garden, without having wires trailing behind them. A wireless network is often referred to as a Wi-Fi network, which stands for Wireless Fidelity and is based on the 802.11 wireless standard.
It is also possible to create a home network which combines both wired and wireless technology.
There are distinct advantages and disadvantages as to whether you opt for a wired or wireless network in your home. A wireless network offers you more freedom to move around your house with your laptop and of course without the need to trail wires from each fixed computer. It is also easy to add more computers to the network without having the need to buy more networking equipment. However, where a wired network offers less freedom, it is cheaper to install and potentially faster due to the connection being rarely interrupted. A wireless network also has restricted boundaries, whereas a wired network is only restricted by the length of cables you have.
In order to set up a home network you will need to purchase some specific hardware. Knowing what hardware to buy is often quite daunting due to the amount on the market, and the fact that you do not know exactly what something is and what it does! Essentially the main piece of equipment that you will need is known as an ACCESS POINT. This is the small box with all the flashing lights that allows the connection between the computers in the network to take place. There are several types of Access Point, and although they essentially do the same job, the type you need (and you may need more than one) depends on your computer, internet connection and they type of network you wish to set up.
To make sure that you choose the right Access Point, we have constructed a guide to the various pieces of hardware to ensure you purchase the parts you need to set up your own home network.
Router: The most important piece of hardware on a home network setup. The router is the part which routes the data to the computers on the network. It basically connects all the computers together so that they can share the internet connection and browse it at the same time. The router also acts as a line of defence between the internet and your computer. Most have built-in software to protect your identity and your computer from viruses.
Hub: The device used to connect the computers to the network via Ethernet cabling or via Wi-Fi. Wired hubs come with a number of ports which can transmit data at speeds ranging from 10 Mbps to multi-gigabyte speeds per second. The hub transmits the data it receives, often from the households' main computer, to the other computers that are connected to it. The amount of computers that can be connected to a hub depend on it size. The average hub can connect 4 computers. A larger hub could connect nearer 50. A wireless hub can connect hundreds.
Switch: This is a type of hub that controls the way that multiple devices use the same network so that each can operate at optimal performance. A switch acts as a networks traffic police: rather than transmitting all the packets of data it receives to all ports as a hub does, a switch transmits packets to only the receiving port. Switches are fast replacing hubs as a preferred choice of data management as prices are more in line with hub prices.
NIC (Network Interface Card): A type of PC adapter card that either works without wires (Wi-Fi) or attaches to a network cable to provide two-way communication between the computer and network devices such as a hub or switch. A Network interface card can be installed internally into a desktop PC or slotted into a Type 2 PCMCIA slot on a laptop or PDA.
Combined switch/router: A popular choice of Access Point as it combines both the functionality of a router and switch in one unit.

How To Get Wireless Set Up Through Windows
Autor: Hutchirg
It was supposed to be so easy, wasn't it? Well, usually it is -- but sometimes, for some reason, Windows just doesn't want to play ball. Here's a quick guide to what to do when you've plugged in all your wireless equipment but it's not connecting yet.
Insert the CD.
It's not enough to just plug in your wireless card the first time you use it -- you need to put in the CD it came with and install the drivers. If you've already done that and there's still nothing, then you might need to update your drivers by paying a visit to the manufacturer's website.
Note that the instructions below apply to Windows XP. If you're determined to use Windows XP, then what you need to do next will be different depending on your wireless equipment's manufacturer -- you should take a look at your manual.
Use the Wireless Network Setup Wizard.
While it's easy to use Windows to connect to an existing wireless network, you still need to create the wireless network to begin with. Don't worry -- once you've created it once, your whole network will be able to connect to and remember it, even if the computer you used to create the network is never switched on again.
The easiest way to open the Wireless Network Setup Wizard is through the Start Menu: go to All Programs, Accessories, then Communications, and you'll find it there. If you can't find it, you might need to visit Microsoft's Windows Update at http://windowsupdate.microsoft.com to get it.
The first thing to do when the wizard appears is read the welcome message, and click Next. Type a name for your network -- anything will do, as long as it's relatively unique to you. You're allowed up to 32 letters to express yourself, but remember that your neighbours might get to see this name at some point! If you bought equipment with WPA (stronger encryption), tick that box. Click Next again.
Unless you have a USB flash drive (it's unlikely), choose the option for manual setup. Don't worry -- it's just a matter of printing out some settings and entering them into your other computers. If you don't use encryption, you can usually skip this step.
It Still Doesn't Connect.
On one of your other computers, right-click on the wireless icon in the bottom-right corner of your screen -- it looks like a small computer with two lines on the right of it. On the menu that appears, click 'View Available Wireless Networks'. Now, you should see a list of the wireless networks your computer is in range of. Look for the name of your own network. This will be the name you typed in the setup wizard earlier or, if you use a router, it will probably be the name of your wireless equipment's manufacturer.
Note that this is the screen to come to if you ever want to connect to a wireless network other than your usual one -- just double click the one you want, wait a while, and it should work.
The most common problem is to find that your computer is trying to connect to another network near you, usually one belonging to your neighbours. If their wireless network has an unnecessarily wide range, it's not at all unusual for you to be able to receive their signal in your house -- I sometimes find as many as five networks in my area available to connect to. Fun as it would be, though, to go through all their shared files, your priority right now is getting their wireless network out of the way to let you connect to your own.
Getting on Your Network.
To make sure Windows knows which network is yours, you need to click 'Change the order of preferred networks' on the left of the available networks screen. You should click the 'Add' button to add the name of your network to this list, and use 'Remove' to take away any that aren't yours.
When you've highlighted your network, click Properties, and then go to the Connection section. Make sure 'Connect when this network is in range' is ticked. If all else fails, you might have to take your printout from the Wireless Network Setup Wizard and enter that information on each computer.

The Truth About Bluetooth Headsets
Autor: pfmmg2
Everywhere you look, companies are producing Bluetooth Headsets faster than the rising cost of gasoline. Nokia, Sony, even Verizon Wireless is unveiling the newest trend in Blue Tooth technology, the headset. Demand is high, and understandably so. Studies have shown that many accidents occur while people are dually driving and speaking on cell phones. A Blue Tooth headset can solve the problem by freeing both hands for the wheel and allowing people to focus their attention on the task at hand-driving.
Now, for those who are unfamiliar with Blue Tooth and headsets that utilize this mobile technology, don't let the name fool you. Maybe you have conjured up images of geeky brains in MIT walking down the street with electric pulsating wires stemming from football helmets as they signal to each other in modified walkie talkies- nothing could be further from the truth. Today's modern headsets are little more than a comfortable, small and lightweight piece that rests over the ear. This technology is revolutionizing the way people communicate wirelessly and if modern manufacturers and patents are a clue to the future, will soon replace the traditional hand held cell phone.
Not exactly a headset, but you can see a great pair of Blue Tooth wireless sunglasses worn by "Dog" on the A&E hit series, "Dog the Bounty Hunter". I wonder what other nifty gadgets the Dog has on the show! But if you look closely, you can catch the Dog speaking into his glasses (no and not in common "Bond" spy fashion) and see the rest of the team hear his words loud and clear.
With the announcement that Verizon is releasing the Logitech Headset and making it available to all of their wireless customers, we are sure to see a sudden rise in the amount of Bluetooth headset wearers.
As testament to the sudden interest in headsets, the company Late On has just received an order for their mobile headsets to be released. These headsets are so versatile; they can be clipped on to a collar and are perfect for conducting phone conversations, as well as for listening to MP3 files.
One of the world's leading manufacturers of mobile phones is also embracing the design of Blue Tooth headsets, Nokia. With three new Nokia headsets soon to be released we can see that the major companies are investing their own dollars in the production of these wireless devices that give users greater freedom and mobility. The world is pulling the wires on many of their devices and now we can see that Blue Tooth headsets are winning the race in mobile technology, with hands waving freely at the finish line.

How The Advancements In Wireless Technology Have Totally Changed Our Lives
Autor: teahupoo
Wireless technology has literally changed our lives. This up and coming method of communication has literally changed the way we live. Many of us cannot imagine a day without using a wireless device. In fact, we use them so much, that we barely recognize them as wireless anymore.
Telephone lines were originally designed to send news reports. Ever heard of getting something over the wire? Journalists still refer to their Associated Press reports as coming over the AP wire, though they most likely travel through the air like all other pieces of information. The invention of the radio demolished the idea of news sent over a wire. In fact, it completely destroyed the concept of the telegraph and eventually the landline telephone.
Computer networking works in a similar manner. Who would choose an immobile stationary system over a wireless one? Why would you choose to actually be chained to a desk when you could move freely about, accessing the internet and other files on a network from the comfort of a couch, a recliner, or a coffee shop. Additionally, while many believe that wireless costs more, this price too is going down, and soon anyone will be able to afford a wireless connection.
WiMAX, short for Worldwide Interoperability for Microwave Access, is steadily making its way unto the wireless market. Its biggest advantage lies in the distance that it spans. Instead of a wireless connection reaching a few meters, it will reach kilometers. Currently some of the strongest WiMAX network reach over 30 miles. It literally spans the length of metropolitan areas, and thus with WiMax, you'll no longer have to search for hot spot sign. Check out wimax.weblongsinc.com for more information about this up and coming form of wireless technology.
Bluetooth has become a mysterious wireless term to non-geeks, but its quickly becoming a household word thanks to its technology in cellular phones. Bluetooth basically is a way to connect hardware. The hope is that instead of seeing a mass of cords behind your television, you'll just have the necessary blue tooth hardware, a wireless connection that connects your DVD player to your television. Everyone hates those mass of wires, or any mass of wires that threatens to ruin the aesthetics of a room, and Bluetooth has the potential to improve the look of just about any system.
Eventually wireless technology will make life simpler. We'll be able to do things in places that we never imagined before. After all, who would think that you could contact a person from across the globe while sitting in a cafe across town, with no cost to either of you. Grandparents in California can talk to their grandkids in Florida while soaking in the rays on the beach. I predict that not only will wireless make life simpler in the future, but that we'll function with it so smoothly, that we won't even notice the wireless technology.

Set Up A Wireless Network And Unchain Yourself From Your Desk
Autor: teahupoo
You no longer have to go to Starbucks to enjoy wireless Internet connections. That's right, you can enjoy your coffee from the privacy of your home and access the Internet. Wireless Internet has come home as well, and Internet connections can now be shared among family members without stringing wires through the living room. On the negative side, however, setting this up can be quite a chore.
With a wireless network, not only can you share Internet connectivity, but you can share files. You can put a file on a shared drive, and then anyone on any computer in your house can access it.
Additionally, you can share a printer. You can literally press "print" while working on your laptop in the bedroom, and the printer in your office will start spewing out your latest reports.
To start out with, you need a gateway the Internet. Any computer can serve as your gateway. This system must be directly plugged into the Internet in order for other users to be truly wireless. Thus one computer is stationary, you cannot move it.
To connect your wireless systems to the Internet, set up your gateway. Click on the Start menu and scroll up to the Control Panel. Then double click the Network Connections icon. At this point you can run through the series of steps in the Network Set up Wizard. Make sure to select "set up a home or small office network."
Continue moving through the wizard until you reach the "select a connection method" page. You'll need to select the option that states that your computer is directly connected to the Internet. Keep moving through the steps until you arrive on the final page with your reward: the finish button.
At this point you only have one computer hooked up to the Internet, and you can't move it around the house. To gain mobility, you'll need to go through the same steps with each of your other computers, only this time, you should select the option that states you're your computer is connected to the Internet through a network and not directly connected to the Internet.
Unfortunately this sort of network does have a downside: the wireless connection relies on the gateway. When you turn your gateway off, the rest of your systems drop their Internet connection too. You might also want to consider purchasing a wireless router. Check out our article configure a network that always stays on.
Overall a wireless connection offers the freedom that no other Internet service does. You can even sit outside your home within a reasonable distance and access the Internet. Imagine that: shopping online from your deck. You could work from the kitchen, the bedroom, and even the bathroom. And while no one wants to become a workaholic, some people need the variety of setting to stay productive. So take the necessary steps to get hooked up and go wireless today.

Extending The Range Of Wireless Networks
Autor: kensnow
Although a wireless transmitter is limited in its range, wireless extension points can be installed to boost its signal and make the range of the network much larger. These wireless extension points are commonly known as repeaters.
Several companies have started to manufacture wireless repeaters, despite the fact that these devices are not part of the wireless standard. Wireless repeaters are designed to resolve certain problems with wireless coverage. The further away you are from where the wireless signal originates, the weaker the signal becomes. Eventually, you can't receive the signal at all, regardless of what equipment you have. The problem is sometimes addressed by running wires out as far as the network coverage is desired, and then have it 'break out' into wireless every now and then using a wireless access point. This is generally more trouble that it is worth, since the idea behind a wireless network is to avoid installing wires! Wireless repeaters resolve the problem in a much better way.
Wireless repeaters work as a relay, taking existing wireless signals and making them stronger. This makes the range of a signal bigger each time. If the repeaters are placed correctly, you can move computers a considerable distance from the wired portion of the network, the router or access point, for example, without failure. The single requirement of this arrangement is that the extension points must overlap; a repeater can't repeat signals that it doesn't receive. Since wireless networking signals are essentially radio signals, repeaters take all the radio signals they receive on a specific frequency and use their power to amplify the signals and rebroadcast them. The signal is not degraded in this process, so it can be repeated as many time as required.
Theoretically, wireless repeaters could be placed in a line for several miles, extending the network out that far, and because these extension points don't need complicated computer technology to operate, they are much cheaper than routers or access points. Some companies combine repeaters and direction antennas to link to LANs that are several miles apart. This is a cheaper method than worrying about connecting over the Internet or installing their own underground lines. In the future, repeater technology could create wireless networks that cover entire cities.
As a consumer, you are currently limited to getting your repeater from large manufacturing firms such as Linksys and D-Link. These companies call their repeaters by different names, including Linksys' Range Expander and D-Link's Range Extender. There are several issues to consider when buying a wireless extension point. The most important is to make sure that it is compatible with the equipment you have. Because there is no standard for wireless extension points, you're better off staying with the same company that makes the rest of your equipment or at least investigate whether any new equipment will work with your system. You should also find out whether an extension point has any Ethernet ports. While it isn't necessary that this is included, it is useful if you want to connect the extension to a wired network. This issue arises basically if you want to connect two LANs in a wireless manner.

Why You Shouldn't Be Afraid Of Wireless Routers And Networks
Autor: teahupoo
Many people are afraid to consider a wireless router because wireless routers are relatively new technology. But wireless routers can really simplify Internet access in your home, small business, or large company.
With a regular Windows Internet network you are easily able to access the Internet from any of your computers that are connected to the Network. Most small businesses are extremely happy with this type of set up. The problem that many businesses run into is that the modem has to be on before any of the other computers are able to get Internet.
For businesses that are use to turning off all their equipment in the evenings, remembering to turn the modem on in the mornings can become an ongoing issue.
Sometimes employees may even spend hours with technical support trying to figure out why their Internet is not working, when the problem is simply that the modem was never turned on. A wireless router can solve this dilemma very inexpensively.
With a wireless Internet router all your computers can have Internet accesses easily without worrying about the modem computer being turned on first. Plus employee laptops can easily access reports and other business material without first having to save information to a disk and transfer it to their office computer.
When looking for a wireless router you need to look for both price and quality. You definitely do not want to skimp on this piece of equipment. Look at the speed of the router as well as its range. You want to make sure that you choose a router that will be able to handle the Internet access for all your office computers, this means finding a router that has enough speed to comfortably keep all your employees connected to the Internet at the same time.
Residential customers and very small businesses are all finding the convenience of wireless Internet a great thing. The easy of use that a wireless router provides is perfect for almost any person or business. Plus you don't have to be a technical genius to install a wireless router at home or in a business.
Most wireless routers simply get plugged into a hi-speed Internet line and you go through a basic step by step computer set up. Some computers don't even need a set up process and they will automatically recognize the wireless router and connect to it.
After plugging in your wireless router you might need to have a brief conversation with your Internet provider to register your device and confirm your set up. But after that, you are really off and running. You can connect as many computers as you would like to your system and easily use laptops throughout the office. Plus you will no longer be wasting man hours trying to figure out why your Internet is not working, when the problems was simply that the main modem computer had not been turned on yet.

Wireless Networking: What It Is, What It Does, And How To Use It
Autor: adrianadams
Wireless networking involves a computer network that transmits data. It is commonly called WiFi. Wireless networking is used to transmit internet service to a large number of customers from a central internet service provider. This is the result of technology advancing to meet the demands of the consumer when it comes to computers and communications. Wireless networking has dramatically changed the way we access the internet, and the impact it has on our lines.
Everything plugged into the network can work together, such as your printer working with your computer to print something you accessed on the internet. Wireless networking relies on a router to receive the transmitted materials and read them. The same router brings information in and sends it back out. A wireless router can handle large volumes of data in just a few seconds, allowing everything to operate very quickly for you.
Wireless networking has lead to millions of individuals relying on their computer for work and for organizing their life. Many of us turn to the internet for everything. We read the news, shop, check the weather, get directions, compare prices, read reviews, even watch movies and listen to music. Wireless networking has allowed the internet to grow and to give us this access to this type of information anytime we want it.
The most common type of wireless networking is the Local Area Network, known as LAN. This involves using radio waves to transmit the data between computers on the same network. Global System for Mobile Communication, or GSM, has three systems - the base station, operational station, and support system. They one you will use is going to depend on your wireless networking needs as well as what is available from service providers in your area. It is likely you with have a LAN server. Both types are effective.
Setting up a wireless network is very simple as well as inexpensive. They are well received because they allow you more mobility with your computer or laptop as there are no wires or cables to be concerned with. With so many of us being on the go in our society, this is the perfect solution for getting everything accomplished. Especially when you consider how many of us use a computer for our personal activities as well as for work on a daily basis.
A wireless network is the perfect solution for sharing resources including internet connections, data storage, printers, and software. It is also enabling more individuals in the work force to operate out of their homes instead of having to commute to an office.
There are some disadvantages of wireless networking that you should be aware of as well. The connection is often slower. You won't notice it for most of you internet activities, but you will be able to tell a difference when it comes to downloading videos. Due to the limited amount of bandwidth, you may not be able to get online when you need to.
Wireless networks are also easier for hackers to access because they can get into the signal. Security has been a huge issue with wireless networking, and one that the service providers are striving to improve upon.
Compatibility issues are another area of frustration for consumers. Third party certification has been working well to eliminate some of these compatibility issues, but many things still have to be improved upon. You may find the troubleshooting process very difficult with wireless networking because there are too many variables to contend with.
Each individual will have to decide if what wireless networking has to offer them out weighs the disadvantages. Many people find wireless networking to be a viable solution for them, and they make it work. Expect to see many changes to the area of wireless networking as providers continue to improve their wireless networking services.

Wireless Networking: The Cutting Edge Of Technology
Autor: adrianadams
One of the fastest growing and most exciting technologies these days is devices that use some sort of wireless network. Wireless networking has allowed almost anyone to use many different devices in a way that not too long ago was unheard of. The most exciting thing about wireless networking is that the development of new technologies is only just beginning.
A new wireless protocol, 802.11N, should be released later this year, which will allow wireless networks to connect over longer distances, and at faster speeds. With this new advancement companies will be able to allow all of their users to connect to the network wirelessly.
This new protocol, coupled with recent advancements in secure connections to wireless networks, will allow businesses to perform tasks wirelessly that they have never been able to do before. Companies utilizing this new protocol will also be able to save quite a bit of money trying to hard wire their offices, by using less wireless routers to do the same task that wired routers did in the past.
Wireless networks have become a very important part of many businesses, because you can construct a wireless network that is separate from your main network that only allows visitors access to the internet and not to any of your precious information. This will also allow you to setup places for visitors to connect to the internet that do not require a desk to be setup or a dedicated computer setup for their access. Instead you can utilize a sitting area and a laptop to achieve the same functionality, without the security risks of someone connecting directly into your network.
Many of the reasons why wireless networks were a faux pas in the past have been addressed and now wireless networks are looked at more and more as a viable alternative to a hard wired network. The best thing about wireless networks is that many new technologies are being released every year that extend the functionality and availability of this fascinating new technology.
The new technologies that are available to construct, and connect to wireless networks is unbelievable. You can connect to a wireless network with a laptop through Wi-Fi, GSM, and even through satellite data cards. Many businesses are creating free hotspots that allow their patrons access to the internet to conduct business, or just send a friend an email.
Many car manufacturers are now offering satellite broadband internet access from within a certain distance of the car, so that people can get an internet connection while they are traveling. Many new types of cell phones and PDAs will allow you to check your email, get your contacts, your calendar, and even access certain web pages right from the phone.
Right now many web pages are not easily viewed, or fully functional on a cell phone or PDA, but many programmers and web designers are working on making their web sites more accessible from all forms of wireless devices.
Many other forms of wireless devices are now being developed that will allow information to be obtained in real-time over great distances. RFID has revolutionized process chain management, because now businesses can track their product from manufacturing to delivery, and everywhere in between. New technologies have been developed recently that allow RFID wireless networks to be formed that can calculate distances between the different devices contained within the network. This will allow a sort of "smart" network to be formed that will allow the devices to "know" when one is on the move, or if one has been lost.
Another very important development in recent years is the use of GPS tracking and navigation. Now we have the ability to know exactly where our products are, and where they are going so we can ensure shipment delivery in a timely manner. When all of these wireless networks are tied together an efficient and productive business can be sure to follow. Wireless networks are a must in this new on-demand world that we live in. If you do not keep up with the times, then you will be quickly left behind.

Network Training for Successful Network and System Management
Autor: hunter
Big companies often have a large network that they need to manage and maintain. This type of system management requires staff that has a computer technical education as well as network training. Without this type of extensive system management large companies would be unable to function as a working whole. Network training gives someone the skills and training that they need to manage and control a large network, as well as make decisions regarding the network that can affect the entire company.
Many of the details pertaining to network management have to do with the security issues surrounding the computer network of a company. There are many issues that have to do with the security of a company that uses computers as one of their main forms of communication with the outside world. This communication via the Internet means that individual computers, as well as the entire network, are at risk when ports to the outside computer world are opened. Network training gives people the skills that they need to maintain a secure system and keep track of the computer network. With secure network management the communication network of a company can be managed and maintained.
The number of network management positions within a company will be determined by the size of the company. The larger the network of computers the more system administration will be needed to keep track of all the system tools and computers. Studies show that companies without any type of network management in place will soon be plagued with issues of down time as their computer system fails to run efficiently. Studies also show that hiring a computer technician without proper network training can lead to an inefficient system as well. As more companies rely on their computer system for communication with their clients and customers, the importance of adequate and superior network management will increase.
Many of the details pertaining to network management have to do with the security issues surrounding the computer network of a company. There are many issues that have to do with the security of a company that uses computers as one of their main forms of communication with the outside world. This communication via the Internet means that individual computers, as well as the entire network, are at risk when ports to the outside computer world are opened. Network training gives people the skills that they need to maintain a secure system and keep track of the computer network. With secure network management the communication network of a company can be managed and maintained.
The number of network management positions within a company will be determined by the size of the company. The larger the network of computers the more system administration will be needed to keep track of all the system tools and computers. Studies show that companies without any type of network management in place will soon be plagued with issues of down time as their computer system fails to run efficiently. Studies also show that hiring a computer technician without proper network training can lead to an inefficient system as well.

How A Router Works
Autor: ricbrajack
In the past when you referred to a router you were talking about a tool that was used to design and shape wood. The internet has changed that.
In its simplest form a router is defined as a device or setup that finds the best route between any two networks. A router is the most important part of a computer network in that it helps data get where it is supposed to be. When it is given the choice of where to make it's delivery one of the tools a router uses to decide where information should go is a configuration table. A configuration table is a collection of information, including:
- Information on which connections lead to particular groups of addresses
- Priorities for connections to be used
- Rules for handling both routine and special cases of traffic
The internet is really an unbelievable invention. Think about this. You can send an email to someone anywhere in the world and they receive your message in a matter of seconds. You can download a file or surf from web page to web page very easily today. All of this because of routers.
An easy way to understand a router is like this. You send a letter to a friend in Australia. They read it and send it back to you. This might take several days or weeks with snail mail. On the internet routers are the mailman that gets your letter to your friend and then their letter back to you.
Routers are very versatile. For example they allow two computers to receive the internet under one IP address simultaneously. An IP address is what allows your computer to connect to the internet. If you have a network of computers a router will allow them to use the Internet with the same access.
In many households today a cable modem is the router. The internet is accessed through the modem directly into a computer. If you have more than one computer you can purchase a router and connect it to the cable modem. The internet is passed through the router and delivered to the computers either through a wire or more commonly today now through wireless technology.
Wireless routers allow you to connect computers, portable computers, personal desk assistants, and printers without using wiring. Wireless routers are excellent for connecting notebook computers to the Internet and networks.
As you are running more computers on your network you may experience a slight drop in speed, but today many broadband routers are able to deliver the internet without much of a slowdown. You probably will not even notice it.

Creating a Fool Proof Data Archive System with a Magnetic Tape Library
Autor: trycmcw
Most businesses have laws and regulations for how long specific data must be stored, but still many companies don't have a tape drive, tape libraries, secondary storage or any plan for archiving data. Even if your industry doesn't have specific requirements, keeping a well documented business information library is a safe bet. Recently, the residential building company Urban Renaissance Agency realized that it had lost archived building plan data for 555 (31%) of its condos due to "insufficient storage measures."
The mistake not only made the news, but will cost the company millions to recover. Data storage tends to be one of those problems that many individuals and businesses don't act on until a loss happens. Most people agree that backing up data is important, but feel the process will be too difficult and the issue stays below the radar until a crisis occurs. On the contrary, it's surprisingly simple to back up, store, and recover data using a tape backup drive and magnetic tape libraries to build a foolproof information archive system.
A tape drive is a very reliable method of recording and archiving data. Using a magnetic tape cartridge, the tape drive scans all of your computer's files and copies them onto the tape. Businesses might choose to backup files daily, weekly, or monthly. The process can be set up to be manually run or to automatically update at a certain time of the day.
The most important functionality of a tape library is that you have a record of 'snapshots' as data appeared at regular intervals throughout history. This means if a customer has a dispute over a contract or a policy from last year, you can pull a tape from your tape library and find the piece of data exactly as it looked one year ago.
Another benefit to storing your data on tape is that cartridges can be stored off site and/or in fire and flood proof containers. More often than not, secondary storage is usually found in the same building as the original data, and often in the same location as the server. With a tape backup drive, once the tape is made the tape cartridge can then be stored anywhere. Because the tapes are there for reference and not part of daily use, they can easily be locked away and stored in disaster and theft resistant safes.
Tape drives come with a variety of options including file cataloging features; a comparison feature that will check the data on the drive against a current document, and are available in a variety of speeds. The tapes you'll use to build your tape libraries will vary as well. It's recommended to discuss your options with a data storage specialist who can help you build a system around your budget and your unique business needs.

What are Homemade Batteries?
Author: mildredvptl
The homemade batteries as the name suggests are made up of the items that can be easily found in the house. The electrolyte of the cell is made up of the fluid that contains charged particles. Smaller units of electricity can be generated from the glass of soft drink, lemon or potato by inserting two electrodes in this liquid. In this way, homemade batteries can be developed. There is a clock named “two-potato clock” which contains a pair of cells and two electrodes connected to each potato or lemon. They are wired in series in order to form a battery through which sufficient current can be passed to generate a digital clock.
Remember that the acids when present in the water will form ions which serve as the charged particles in the electric current. One of the examples of homemade batteries is the lemon battery. The citric acid is present in the lemon juice. The batteries made of lemon are formed by placing two electrodes of zinc as anode and copper as cathode in the electrolyte which is the lemon juice. Make sure that they do not touch each other. Another example of homemade batteries is the potato battery which works very similar to the lemon battery. The only difference is the electrolyte in the potato battery is the phosphoric acid. You can also make homemade batteries from the fruits and vegetables.
The homemade batteries can be used much in the real time because the power generated by them is extremely low as compared to the commercial batteries.

Computer Networking Fundamentals
Autor: secmit
A computer network is a collection of two or more computers with communication between them through a medium. The communication medium can be through radio waves, wires, infrared, optical fibers etc.
Computer network is an integral part of our daily lives, with the most important reason being that of communication. The use of computer networking is to share resources like fax machines, printers, modems, files etc., and its other uses are database server, computer server, email, chat, internet etc. The computer to which the resources are attached is called the server and the other computers that access the resource are called clients. In peer-to-peer computer networks there are no servers.
The sharing of fax machines, printers, and modems amongst many computers and users reduce the operational cost. A database on a computer network is a very important application as it stores and runs many important data and jobs. Emails and chats can be used for instantaneous communication and sending of files on a computer network.
The computer networks are classified, depending upon the size, as Local Area Networks (LAN), Wide Area Networks (WAN), Metropolitan Area Networks (MAN) and Personal Area Networks (PAN). The topology (topology is the way the computer networks and network resources are connected) of the networking can be classified as Bus Network, Ring Network and Star Network.
The networking hardware basically consists of wiring, network cards and a hub. Computer network cards are required so that one computer can understand what the other computer is "talking". Network cards have a unique MAC address to identify computers on a computer network. Hubs connect all the computers in the network. Hubs can also be used to connect to other hubs to increase the size of the computer network. Two computers can be connected using Ethernet cards or phone lines or power lines for communication, with hardware kits available at roughly a cost of $100.
As the number of computers in an office or a home increases, so do the number of cables, so wireless networking is a viable solution. In wireless networking radio transreceivers or infrared signals are used to communicate between computers and devices. Examples of wireless networking include Wi-fi and Bluetooth technology, though there may be security issues involved in wireless networking. However there definitely is a stronger preference towards wireless networking nowadays among consumers.
Computer networks have added a new dimension to the 21st century. Today the cyber world is much faster and wider than the real world. This has all been made possible due to computer networks. Computer networks have revolutionized business, communication, travel, research, defense, society and almost all human endeavors. The evolution of computer networks has helped the technological revolution take a big leap forward.
