There are several protocols including NetBeui,
IPX and TCP/IP.
NetBeui (NetBios Extended User Interface) is a protocol that Microsoft has used heavily. It is designed for use on small networks.
IPX is Novell's networking protocol. Like NetBeui is is small and fast and can run with larger networks.
TCP/IP is the standard for internetworking.
TCP/IP runs around multimultiple networks is has become the standard for
networking. We will therefore concentrate on this prorocol, although
all three potocols are similiar in many respects.
TCP/IP is involved with four of the seven layers that make up the OSI 7-layer Reference Model:
Network Layer Handles movement of packets around the network.
Transport Layer Provides flow of information
between hosts, TCP/IP
protocol and UDP protocol
Application Layer Implements the application
