Why do we use sockets?
Sockets allow you to exchange information between processes on the same machine or across a network, distribute work to the most efficient machine, and they easily allow access to centralized data. Socket application program interfaces (APIs) are the network standard for TCP/IP.
How socket plays an important role in connecting to server?
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.
Who uses socket programming?
Socket Programming using TCP/IP | HackerEarth. Socket programs are used to communicate between various processes usually running on different systems. It is mostly used to create a client-server environment. This post provides the various functions used to create the server and client program and an example program.
What are the applications of socket programming?
How does a socket work in a network?
A socket is a pseudo-file that represents a network connection. Once a socket has been created (identifying the other host and port), writes to that socket are turned into network packets that get sent out, and data received from the network can be read from the socket. Sockets are similar to pipes. Both look like files to the programs using them.
What is the definition of a socket in Java?
Definition: A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.
What is the difference between a socket and a port?
A socket is effectively an application ID as it is the combination of port and IP address that the application is using. Both end of the connection will use a socket regardless of whether they are streaming data or sending datagrams (UDP).

How is a socket bound to a port number?
A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to. An endpoint is a combination of an IP address and a port number.
