It is a set of communication mechanisms that have made it possible for the local, remote, small or big computer networks to communicate with each other. TCP/IP is based on two communication protocols TCP and IP.
TCP is responsible for processing and handling the data from the different applications and IP is a network oriented protocol that is used for transmission of the data. Transmission control protocol and Internet protocol make it possible for different networks to share data with each other in a variety of ways. Today every network application relies on the TCP/IP.
Some of the major functionalities of the TCP/IP are the following. Today there are several client/server applications use TCP/IP suite.
