Most people are familiar with a few different types of application software, commonly known as “applications” or “apps.” For example, you may already know how to use Instagram WhatsApp, WPS, CamScanner, etc. on your phone.
But the app you use depends on the system software you have. System software for a personal computer is called the operating system (OS).

Operating system is the set of coded instructions that makes a computer operate or function. The operating system is the most important software installed on a computer, because it controls the computer’s most basic functions.
An operating system is the middleman between the user and the computer, and also between the applications and the hardware. It helps the computer start up when you turn it on and shut down when you turn it off.

The commonly used operating system is Microsoft Windows.
Functions of operating systems.
1. Running software programs
The operating system allows multiple kinds of programs, or software applications that perform specific functions, to run at the same time. It gives each program (also known as an application), its own area of memory and makes sure that each one has the resources it needs to run properly.
2. Communicating with users
The operating system translates what a user wants to do—the input data into a form the computer can understand. The operating system can also relay information from hardware or software back to the user.
3. Maintaining security
Operating systems are the gatekeepers of computing resources, keeping programs from accessing the memory of other programs without permission. They also restrict access to files and programs, often by requiring passwords so that only authorized users can access data stored on the computer.
4. Starting the computer
5. Providing a user interface
The operating system provides the user interface, which can be thought of as the things you see on the screen and interact with, such as icons, buttons, and menus.
Note: The Android operating system was designed exclusively for mobile devices.
