Computer Networking is referred as connecting computers electronically for the purpose of sharing information. Resources such as files, applications, printers and software are common information shared in a networking. The advantage of networking can be seen clearly in terms of security, efficiency, manageability and cost effectiveness as it permits collaboration among utilizers in a wide range. Basically, network consists of hardware component such as computer, hubs, switches, routers and other devices which form the network infrastructure. These are the devices that play an important role in data transfer from one place to another using dissimilar technology such as radio waves and wires. There are many types of network available in the networking industries and the most common network is Local Area Network (LAN) and Wide Area Network (WAN). LAN network is made up of two or more computers linked together in a short distance usually at home, office buildings or school. WAN is a network that covers wider area than LAN and usually covers cities, countries and the whole world. Numerous major LAN can be connect together to form a WAN. As numerous devices are linked to network, it is important to ensure data collision does not happened when this devices attempt to utilize data channel simultaneously. A set of rules termed Carrier Sense Multiple Access / Collision detection are utilized to detect and prevent collision in networks.
