What is the Operating System?

If we see the history of the computer then we found that the computer is not working like today. It does not perform the basic function. It cannot get the character from the keyboard and not display the information as today. The computer cannot perform Logical and mathematical descriptions easily because in those days there is no relationship between computer and User. Computers only understand the machine language so first every code is written in machine language and then process.

Then software (Computer Program) developed which removes the entire problem is called an operating system.

The most important program that runs on a computer is O/S. Every computer must have an O/S to run other programs. Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers.

For large systems, the operating system has even greater responsibilities and powers. It is like a traffic cop — it makes sure those different programs and users running at the same time do not interfere with each other. The O/S is also responsible for security, ensuring that unauthorized users do not access the system

O/S is not a single program. It’s a collection of a group of some programs. The operating system creates a relationship between computer and user. The operating system provides an environment in which the user may execute the program. The primary goal of an operating system is that make the computer system easy to use and the secondary goal of an operating system is to use the computer hardware inefficient manner.
