Client server in C using socket in Linux

The example below demonstrates ongoing communication between a client and server on a Linux system, using a Raspberry Pi board for illustration. Embedded Linux systems are commonly utilized due to their adaptability in sockets, enabling communication between two or more programs regardless of whether they are written in the same programming language. In this tutorial, I will be using the C language.
