A unit for processing data in the form of programs, the computer is one of the tools at the heart of computing. This machine consists of two main parts: software and hardware. The latter includes all the internal and external hardware components that participate in the proper functioning of the device. For example, you have the processor, keyboard, RAM, or mouse.



Software is considered the brain of the computer and therefore constitutes the set of codes and programs that the machine contains. In more technical language, it can be defined as the various instructions that must be followed and executed for a computer to function optimally. There are several forms of software that are distinguished by their various specificities. You have, for example, programming applications that make it possible to develop other programs through languages specific to computers. In addition, you should know that not all software is free to use. Some of them are subject to copyright and require you to pay to have them.
