Network Protocols

Once connected to a network through a NIC , a computer also must be able to use that connection. That is for two computers on a network to communicate with one another successfully, they must share a common set of rules about how to communicate.

At a minimum, such rules must include how to interpret signals, how to identify "one self " and other computers on a network, how to initiate and end networked communications, and how to manage information exchange across the network medium. Such collections of agreed-upon rules are network protocols, or more simply, protocols.

Protocols are:- TCP/IP, NetBEUI & IPX/SPX or NWLink.
