In the late 1960's as large college universities and several research labs gained an ever increasing amount of computers, the need for interconnections that worked at high-speed was great, and the pressure was on. It was not until the mid 1970's that an answer to the demand was created, they called it LAN.
LAN stands for Local-Area Network, with the ability to cover small areas, such as a home or office or group of buildings (schools, warehouse, etc.), LANs have higher data-transfer rates, smaller range and do not require licensed telecommunication lines as opposed to WAN (Wide-Area Network). ARCNET and Token Ring were two LANs that were widely used in the past. Ethernet and Wi-Fi are two of today's most common LANs.
A LAN is an important component to gamers. By setting up a LAN, gamers can link together their computers and play with or against their friends. Games, such as "Diablo II" and "S.O.C.O.M.", allows gamers to cooperate together in a team while either on line or while their computers are connected by LAN.Games, such as "Unreal Tournament" and "Starcraft", allow gamers connected by the internet or a LAN to work as a team or to compete against each other.computers are usually linked by what is known as a Cat-5 cable to a HUB; and the HUB acts like a mediator. The Cat-5 cable connects to the back of the computer through the Ethernet port on the Network card, network adapter, LAN adapter or NIC (Network Interface Card). A network card operates on both the physical layer and the data link layer; it allows a low-level addressing system, using Mac Addresses, also known as an IP address, and physical access to the networking medium (the HUB). Not all LANs are the same; some use cables while others are wireless.
While other network technology exists, since the mid 1990's, the Ethernet network card has been leading the crowd, due to low cost and easy integration and use. A unique 48-bit serial number is on every Ethernet network card, stored in the ROM; the serial number is your computers Mac address. The Mac address for every computer must be unique; otherwise only one computer with a given Mac address could be on line and connected to the LAN at a time. The Institute of Electrical and Electronics Engineers is responsible for each unique Mac address getting assigned to vendors of interface controllers; this is so no two network cards share the same Mac address.
At one point network cards were expansion cards that had to be plugged into the motherboard. Most new computers have the network card built into the motherboard; some may even have two ports built in so the computer can be connected to multiple networks. Some companies have started using optical fiber instead of Cat-5 cables or USB cords, because optical fiber is immune to electromagnetic interference. Optical fibers are made of glass or plastic, instead of metal, and carry light along their full length. The electrical signals sent along the optical fiber degrade less during transfer than signals sent along metal wires (Cat-5 cables and USB cords).

Gaming consoles have evolved into a set of complex devices and are as innovative and exciting as imagination can make them. These hand held devices are really a rage with the children of today. They are marketed cleverly as stress busters and increasingly even adults have been bitten by the bug. Both children and adults find them addictive and hard to resist. Some people claim that digital gaming is intellectually stimulating than merely entertaining. Whatever is the justification, game consoles are getting to be more and more complex and composite in order to cater to the tastes of both children and adults.
Most of these devices have the ability to support PAL format and most importantly the online compatibility. One can play these games with friends across the globe if one wished to! The graphical images have a high resolution with a colour compatibility of 17 million. While some consoles have a single screen there are others with two screens, one is used for picture display while the other is used for touch sensitive control. The online gaming devices can also be operated by Wi-Fi connection. In addition to the Wi-Fi connection the wireless controller can allow the user free movement.
There are numerous brands and each brand offers a wide range of games. The games may be categorized as sports games, simulation games, racing games, role play games, plat former games, adventure games and fighting games. There are numerous games to select in each of these categories.
Many of these games need accessories to supplement the game. For example, in order to use voice commands or chat online with the other players, the headset is necessary. The AC Adaptor can be used to recharge the battery. A stylus is useful to manipulate the touch screen and so protect it from damage. There is a gaming case to protect it from being damaged. Some Game Consoles also have add ons like the MP3 player and camera. These sleek machines are available in attractive eye catching colours and the accessories are generally designed to match the gaming device.
Some racing games require steering wheels while the fighting games require boxing gloves and they have special controls embedded into them to make them simulate punching. These gaming consoles also use the latest technology like the Dolby and DTS to provide the best sound effects for the enhancement of the game and to ensure real time game play.
