802.11a This is an older wireless networking technology which is not commonly found in use today. Operates in the 5 Ghz frequency range, at up to 54 Mbps, with an approximately 50 foot range. 802.11b This protocol is still found in use today and can offer needed support to some older devices. Operates in the 2.4 Ghz frequency range, at up to 11 Mbps, with an approximately 150 foot range. 802.11g An updated wireless network protocol with enhanced speed it operates in the 2.4 Ghz frequency range, at up to 54 Mbps, with an approximately 150 foot range. 802.11n The latest edition to the selection, this technology is not yet wide spread. Able to operate in either the 5 Ghz and/or 2.4 Ghz frequency range, at up to or exceeding 50 Mbps, with an approximately 600 foot range. An ideal implementation of this wireless network protocol can achieve the fastest speeds of all the protocols. Speeds and ranges listed are under optimal conditions. The 2.4 Ghz radio frequency range is arguably more crowded than the 5 GHz range, although it is typically easier to transmit at greater ranges using 2.4 Ghz. Another factor is that the less utilized 5 Ghz range usually encounters greater challenge when interacting with solid objects which can reduce effective range. A common source of competition in the 2.4 Ghz range will include various baby monitors, cordless telephones, Bluetooth devices and microwave ovens. Bluetooth devices are a pretty common companion to the cell phone, such as wireless headsets. When two or more devices communicate on the same frequency they will often interfere with one another. When this happens, communication difficulty will result. It would be to your benefit to avoid radio communication interference whenever possible. Depending on your environment there may be one or more factors to contend with where interference is concerned. Also consider who your neighbors may be and what electronics they may be using. Wireless networking equipment can offer a variety of features. Some devices will support multiple protocols and radio frequencies. There are also authentication, encryption, port triggering, port forwarding, QoS features and other configuration settings that may be deciding factors.
There are some basic learning wireless networking. I will explain several wireless networking protocols. The wireless protocols you want or need to use will both affect, and be affected by, the wireless network hardware you have. We will assume that the TCP/IP network protocol will be used here along with a wireless local area network protocol.

- The Best Motherboard For Gaming
Expansibility Game's requirement for hardware is advanced with times. Currently, motherboard has a strong expansibility which can support all functions of the dominant products, players can add a SLI video card to further its 3D graphics performance or upgrade to ATHLON64 X2 dual-core processors depending on their needs in the future. Multi-channel capability As a motherboard targeting the game market, it should indispensably compose a superior audio system. DOOM3 brings you to a breathing scene that already on a par with home theatre. If you are using a 5.1 audio system, after making full use of it, I believe you will have a fire-new DOOM3: monsters come to you and howl from all directions --- as DOOM3 positions audio extremely accurately, players only need to target where sounds from and fire. It can be said that your game is not a perfect one when the surround sound in DOOMS is disabled! Fortunately, nowadays gaming motherboards are able to support six or eight-channel outputs and High Definition Audio, what we need is to buy a Speaker over the 5.1 standard. Overclocking overloads the CPU and that would make it at risk. Try to nit this sort of risks in the bud, motherboard makers are competing against each other to launch their new technology such as ASUS AI Overclocking and C.P.R overclocking protection tool, etc.
How to Choose the Best Motherboard For Gaming ?
Many gamers wonder how they can get a motherboard that would has a favorable game result. It is no other than 3D games that are so demanding on performance and consumes so much system resource. When purchasing a gaming motherboard we have to take several factors into consideration.
The Printed Circuit Board (PCB) on the motherboard
As the prerequisite for a stable operation of a motherboard, the layout of PCB traces and various types of electronic components is very important. Considering the shield of PCB lines and signals interference, nice traces should let all the lines on the PCB board distribute uniformly.
A best motherboard should use a 6-layer PCB board with steady color, smooth finish as well as neat welding and regular arrays of all parts, or else instability and faults would frequently occurs when overclocking the motherboard.
Supply circuit
A good few gamers prefer high-frequent and high-powered CPU, which would consume lots of energy even when working in the default frequency, let alone overclocking. For example, the maximum current of present Prescott core P4 has already reached 91A, power consumption is close to or over 100W. Thus you need a motherboard that can supply enough power and stable voltage to ensure a smooth system.
Motherboard overclocking
Presently a great many motherboard manufacturers have done quite a lot of user-friendly overclocking researches for their products. Famous brands like Intel, ASUS and GIGABYTE etc, generally will offer hard jumpers, BIOS settings combining with specific overclocking software, which have make your overclocking much simpler.

- Wireless Or Wired LAN
LAN or Local Area Network is a kind of computer network that covers a local area, and in which an office, home, or some buildings, existing near to one another are often included. Usually, local area network is developed by using some devices in local proximity and it has fix distance limitations. Local area network can be wireless or wired but it is only for a single setting or location.
A local area network in which two or more than two computers are connected without wires is known as a wireless LAN. Wireless LAN is also called a WLAN. When it comes to the use of wireless or wired LAN for some business, wireless LAN seems to offer greater portability and flexibility than wired LAN. With WLAN devices, users can easily move their laptops and other devices in their offices and homes. This kind of networking requires no wire, so no fears of losing connectivity.
In traditional LAN, a wire is used to connect computers with each other, while in the WLAN, computers are connected by using an access point devices. The devices, which feature wireless network adapters, communicate with the access point and then connected to some wired Ethernet LAN. Usually, the access point devices work in a coverage area of nearly 100 meters (300ft).
Two types of equipments in a wireless LAN include a wireless station and access points. There is a wireless networks interface card (NIC) in a wireless station, and its access points serve as base station for the networks. They receive as well as transmit radio frequency for wireless devices communication.
These days, wireless local area networking is becoming quite popular in many different businesses, as a large number of businesses are conducting their daily business operations by making the most of this impressive and easy to use technology. These businesses believe that the wireless technology allows them to conduct their daily business operations in a safe and secure way. A large number of retail shops, hotels, universities, and hospitals are widely using wireless technology nowadays.
Besides the safe and secure connectivity, wireless LAN also offers some other benefits that include user mobility, quick installation, lower costs, flexibility and scalability. This kind of networking allows users to access different network resources, files and internet without being connected to a network through wires.
You can quickly install it, as you can develop the network connection without including some wires. Initially, you have to invest a bit higher in the wireless LAN, but you can save installation and wiring charges.
It offers great flexibility, as you can install a WLAN for some timely needs like trade show, conference or for some meetings. With this flexibility, you can also take WLAN in your required location. Results of a recent study indicate that a large number of small and large enterprises prefer wireless infrastructure to wired infrastructure, as they consider it safe, secure and easy for carrying their daily business operations.

- Learn About Wireless Networking Basics
More and more people today have multiple computers in their household. With more than one computer in sharing a printer or transferring needed data between computers is a total pain without the help of a home network. With home networking equipment getting cheaper and cheaper it's really easy and affordable to setup a mini network in your home.
Prior to the boom of home wireless networking setting up a home network was a mess. Wires traversing your entire house, the equipment was expensive and home routers and switches were in their infancy and were much more difficult to setup for the novice. Today's routers and switches are nearly foolproof; the GUIs (graphic user interfaces) almost do all the work for you. Almost.
The first thing you should do is get all of your computers prepared. Make sure they all have a NIC (network interface card) that will handle your type of network. By type I mean will you be running a wireless or wired network?
More and more modern house today are installing Ethernet cable (the cable that your computer connects to your internet providers router) in every room. In a perfect world all networks would be wired. As most routers and switches can handle cable speeds that far surpass any wireless network technology to date. But, most of us don't have Ethernet cable ran into every room of our house so we must use a wireless network.
If you are going wireless you must decide on a wireless standard. A wireless standard defines many things but the thing you are most concerned with is the speed the data will travel. Today's fastest home network is wireless N. Wireless N has a throughput rate of 144 MPS (megabits per second). This is more than double the speed of Wireless G. Also keep in mind that wireless N doesn't only provide more speed, it also provides a much greater range. Wireless N has a range of about 300ft compared to 100ft for wireless G. If you have a small house or apartment wireless G is more than adequate. But if your house is medium to a bit on the larger side you must get wireless N. In my house wireless G barely reaches downstairs. When it does it is much slower. With wireless N however, I have no problem in any part of my house.
So choose your wireless standard and then head over to buy your router. Honestly, the majority of routers perform essentially the same. Even though I work for a competitor I always buy Netgear home equipment. But, do your research. Read reviews and find your own favorite home networking company.
Wireless routers nowadays will setup everything for you. Pop in a CD, go through the basic setup procedures and you will be networked in minutes. quite the breakthrough from the early days.
During the setup you should be asked if you want to setup wireless security on your router. This is a must for many reasons but the two important one are protecting your data and protecting your bandwidth. Obviously if your network is wide open so is your data. I am sure you don't want some strangers going through any personal data you might have on your computer(s). And in an unprotected network anyone in your direct area can freely use your internet connection. What this means to you is, depending on how many people are on your network, is a big slow down in speed. So definitely setup a secure network and do not forget your password(s).

- Difference Between an iPod and an MP3 Player?
While the terms iPod and MP3 player are sometimes used interchangeably, there is a major difference between these two devices. They are different in terms of compatibility, brand, price, and battery needs. Read on to learn more about the difference between MP3 player and iPod products...
- BRAND: iPod is specifically a product of Apple Inc, whereas an MP3 player may be sold under a variety of different brand names. These brands include Sony, SanDisk, and RCA; they are usually brands that also make portable CD players or removable storage devices. You can find them almost anywhere electronic devices are sold. They have both become widely popular, and surprisingly affordable.
- COMPATIBILITY: It is possible to use an iPod with recent versions of Windows or Mac OS. Other brands support Windows and occasionally provide Macintosh drivers. A non-iPod player is more likely to work under Windows 98 or 2000, an important difference for some users.
- CAPABILITIES: Both iPods and MP3 players can play MP3 sound files along with various other formats. If either one of these players don't support a specific format, a simple MP3 conversion software can usually convert files in that format to one that is supported.
- PRICE: An iPod will typically cost more than another player with equivalent music file storage capacity. One or two gigabyte iPod Shuffle units are usually priced at about double the cost of a similar generic player (a difference of approximately $20).
- BATTERIES: iPods come with rechargeable batteries and can be charged via USB, while other players may use regular "AA", "AAA" or other battery types, and don't necessarily have a built-in charger. Some people find one option more convenient than the other; either way has its benefits.
Despite the difference between them, the iPod and regular MP3 player have many similarities. They both play digitized music files, have standard 1/8" earphone jacks, and connect to computers via a USB cable. Keep in mind that the term "MP3 player" may also refer to computer software which plays digital audio files.
