Understanding the socket package for network requests

Sockets are the main components that allow us to leverage the capabilities of an operating system to interact with a network. You may regard sockets as a point-to-point channel of communication between a client and a server.

The socket concept is very similar to the use of file descriptors for UNIX operating systems. Commands such as read() and write() for working with files have similar behavior to dealing with sockets. A socket address for a network consists of an IP address and port number. A socket’s aim is to communicate processes over the network.
