The os is a number of special applications that run on the computer that allow it to function properly. Their responsibilities incorporate recognizing input from the keyboard, keeping track of files and websites on the disk, sending output to the display screen, and handling input and output units like ink jet printers.

It manages the main memory, deciding what portion of it is in use and who is using it at any given moment. It uses methods just like paging and segmentation to permit programs to access a lot of mind by deceiving them into thinking that all of the memory on a hard disk or perhaps RAM is one continuous block, raising memory consumption without requiring the computer to be restarted when a program needs more.
It deals with the output and input of components devices, including keyboards and mouses, and makes them suitable for the computer. Additionally, it creates a file directory framework for the computer and deals the storage area of data on long-term non-volatile storage space devices. Additionally, it helps to control the computer’s memory, making certain it is shared among all operations, and that programs have no more than processing power at any point with time.
