Software

For average users, the first two groups of software are important, being operating systems (like Microsoft Windows, Linux, etc.) and application softwares (other programs and applications used - office applications , graphics software , antivirus programs , computer games, or Internet browsers ...). The operating system is the basic software of each computer and it runs from when the PC  starts until when it's shut down completely. It consists of kernel and auxiliary system tools. Its main task is to ensure that the user can work, set up and control the computer (with the help of graphical user interface - called GUI - or simply the desktop and windows in Microsoft Windows) and create a stable environment for application software to run. Generally speaking, the operating system is much more complex than normal programs, and its development is also much more challenging.

Application software consists of programs and applications that are designed to directly communicate and interact with the user. By default, these programs have a graphic control interface for easy and organized handling that also takes care of processing individual tasks and requests the user enters. We can include all of the programs we regularly use in the application software group, but also computer games or navigation software for GPS navigation, etc.
