What is Operating System? Types of OS, Features

Without the operating system, the computer has no existence in itself. No device works without it. Generally, we can say that the operating system is a program that performs operations of other programs since computer hardware does not understand our language. It understands the binary number or the language of 0,1 or the machinery language. Therefore, the operating system hardware acts as a medium between the application system and the users. The operating system manages all application programs with excellent efficiency and simplicity. The operating system works as a medium by keeping the computer running and capable of functioning and converting our instructions in the machine language and our language, such as -MS-DOS, Windows 95, Windows 98, Windows 2000, Windows XP, Windows 7, Windows 8, Windows 10, Unix, Linux, Android OS, iOS, etc.

Due to the operating system, the user does not have to keep information about different parts of the computer, and at the same time, the user can do all his work without any stress. It distributes and arranges the means of the system. There are many other useful departments of the operating system, many of which are performed by the central processor. For example, when printing is done, the central processor leaves the operating system’s work by giving necessary instructions and starts doing its next task.
