Internetworkin involves connecting tow or more distinct nodes or computer networks segments together to form an internetwork (often shortened to Internet} using internetworking devices, such as bridges, switches, router and gateways which operate at the various levels of the OSI Reference Model to connect them together to allow free flow of packets back and both between them . The network can further be divided into various brances or categories, namely LAN, MAN or WAN depending upon specific context of use.
Local Area Network: The network whose coverage falls within the range of 10 m to 1km, that is form small room to the campus of offices is called as Local Area Network.
Metropolitan Area Network : The network whose coverage falls within the range of 1 km, that is, within the vicinity of the city limits is called as Metropolitan Area Network.
Wide Area Network: The network whose coverage falls within the range of 10 km to 1000 km, that is, spanning from one city to another city or may be to another county altogether is called as Wide Area Network.
Today, the Internet is largely and loosely based on the OSI Reference Model that provides us the seven layers as decribed below. gives the comparative schedule used, address supported and lenth of the address.
