Sockets are the main component that allows us to take advantage of the operating system's capabilities to interact with the network. You can think of sockets as a point-to-point communication channel between a client and a server.

Network sockets are an easy way to establish a communication between processes that are on the same or different machines. The concept of a socket is very similar to that of UNIX file descriptors. Commands such as read() and write() ( to work with the file system ) work in a similar way to sockets.

A network socket address consists of an IP address and port number. The goal of a socket is to communicate processes through the network.
