socket programming in UNIX

Socket programming or client-server programming, involves writing the computer program that communicates with other programs across acomputer network. The program or process initiating the communication is called a client process, and the program waiting for the communication to be initiated is the server process. The client and server processes together form a distributed system. The communication between the client and server process may either be connection-oriented (such as an established TCP virtual circuit or session), or connectionless (based on UDP datagrams).
