A network socket is one endpoint in a communication flow between two programs running over a network. Sockets are created and used with a set of programming requests or "function calls" sometimes called the sockets application programming interface (API).
Besides, why do we use socket programming?
Sockets provide the communication mechanism between two computers using TCP. A client program creates a socket on its end of the communication and attempts to connect that socket to a server. When the connection is made, the server creates a socket object on its end of the communication.
What is socket programming in computer networks?
Sockets programming is the fundamental technology behind communications on TCP/IP networks. A socket is one endpoint of a two-way link between two programs running on a network. The socket provides a bidirectional communication endpoint for sending and receiving data with another socket.
Why sockets are used?
A Unix Socket is used in a client-server application framework. A server is a process that performs some functions on request from a client. Most of the application-level protocols like FTP, SMTP, and POP3 make use of sockets to establish connection between client and server and then for exchanging data.
