An operating system is the most important software that runs on a computer.
It manages the computer’s memory and processes, as well as all of its software and hardware.
It also allows you to communicate with the computer without knowing how to speak the computer’s language.
What is the main purpose of operating system?
An operating system has three main functions: (1) manage the computer’s resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software.
How does an operating system work?
An Operating System (OS) is a collection of software that manages computer hardware and provides services for programs. Specifically, it hides hardware complexity, manages computational resources, and provides isolation and protection. Most importantly, it directly has privilege access to the underlying hardware.
What are the types of operating system?
Following are some of the most widely used types of Operating system.
- Simple Batch System.
- Multiprogramming Batch System.
- Multiprocessor System.
- Desktop System.
- Distributed Operating System.
- Clustered System.
- Realtime Operating System.
- Handheld System.
Why do we require an operating system?
There was no operating system. This is why an operating system is needed. It allows a program to run on multiple different types of hardware. An operating system provides a layer between the program and hardware to enable a program to use a standard interface no matter what hardware is used.
