In network communication, a socket is a point of connection between two programs. TCP layers can identify the application that data will be sent to by using a port number attached to a socket. Endpoints are IP addresses and port numbers that are combined.

What Is Socket And Port In Networking?

In order for network processes to be identified within the system, a port is assigned. In a socket, both ports and IP addresses are present. In this case, “Socket” refers to the combination of port and IP address. Software that uses the word “Port” refers to a port number.

What Is Socket And Its Types?

Socket type



Transmission Control Protocol (TCP)


User Datagram Protocol (UDP)



What Is The Network Socket Called?

As a result of the proliferation of TCP/IP protocols on the Internet, the term network socket is usually used to refer to the Internet Protocol (IP) and the TCP/IP protocols. In this sense, it is also known as the Internet socket.

Why Are Sockets Used?

The sockets allow two different processes to communicate with each other on the same or different machines. The term “standard Unix file descriptors” refers to the way it is used to communicate with other computers. Client server applications are built on a Unix socket.

How Do Sockets Work?

Client and server interactions are commonly handled using sockets. Client-to-server connections involve the socket on the server process waiting for requests from clients. In order to do this, the server first establishes (binds) an address that clients can use to locate the server.

What Is The Purpose Of Socket?

Stand-alone and network applications can both benefit from sockets. The sockets allow you to exchange information between processes on the same machine or across a network, distribute work to the most efficient machine, and make it easy to access centralized data from anywhere.
