Main function of Operating System in a computer system and how they works ( Part 1 )

As we all know , Operating system of a computer is that powerful application that enables one to run some certain program on our computer system and also has the function of performing some additional task.

The operating system is the most important program that is on a computer. The operating system basically runs the computer and allows other programs to run as well. The operating system does all the basic things that a computer needs to do, such as recognizing inputs from the mouse or the keyboard. It keeps track of where all the files are on the computer. It allocates resources to the various programs that are running and it prevents unauthorized access to the computer.

The most popular operating system today is Microsoft's Windows operating system. Macintosh computers have their own operating system, the most recent of which is called Mac OS X. There are also open source operating systems such as Linux.

Operating system is a platform between hardware and user which is responsible for the management and coordination of activities and the sharing of the resources of a computer. It hosts the several applications that run on a computer and handles the operations of computer hardware. There are different types of operating systems. These are as follows:
1. Real-time Operating System: It is a multitasking operating system that aims at executing real-time applications.
2. Multi-user and Single-user Operating Systems: The operating systems of this type allow a multiple users to access a computer system concurrently.
3. Multi-tasking and Single-tasking Operating Systems: When a single program is allowed to run at a time, the system is grouped under a single-tasking system, while in case the operating system allows the execution of multiple tasks at one time, it is classified as a multi-tasking operating system.
4. Distributed Operating System: An operating system that manages a group of independent computers and makes them appear to be a single computer is known as a distributed operating system.
5. Embedded System: The operating systems designed for being used in embedded computer systems are known as embedded operating systems.

Operating System is a software program that acts as an interface between the user and the computer. It is a software package which allows the computer to function.
