Before I wasn’t familiar with regards to computer networking, I don’t even know what it means. On our first week we tackled about computer networking fundamentals and I have learned that it is a collection of individual networks, connected by intermediate networking devices, that functions as a single large network. The networking devices are the vital tools for communication. Whenever you have a set of computers or networking devices to be connected, you make the connections, depending on the physical layout and your requirements Depending on the physical layout or topology of the network, there are three types of networks. LAN stands for Local Area Network. These networks evolved around the PC revolution. LAN s enabled multiple users in a relatively small geographical area to exchange files and messages, as well as access shared resources such as file servers.WAN stands for Wide Area Network. The interconnection of various LAN’s through telephone network, which unites geographically distributed users is achieved through WAN. In short when we log on to the internet, we become a part of a WAN. MAN stands for Metropolitan Area Network. It is usually the interconnection between various LAN’s in a particular geographical area like a metropolitan city like Bombay.
