Operating system

Operating system is the first program that is loaded into the computer. The process of loading the operating system is called booting. Operating system manages computer's hardware and software resources. It acts a link between the software and the hardware. It controls and keeps a record of the execution of all other programs that are present in the computer, including application programs and other system software.

 

Need for an Operating System

 

The operating system helps you to communicate with the computer. Without OS you cannot use any computer or mobile device or any software like word-processing software, spreadsheet software or any other application software. It makes computer user friendly. It allows computer to use resources efficiently and effectively. It is designed in a way to permit effective development, testing and introduction of new functions without interfering with the service.

 

The operating system is the backbone of any computer system as it performs the following basic tasks.

·      Recognizing input from the keyboard

 

·      Sending output to the monitor

 

·      Keeping track of files on the hard disk
