The operating system is a collecting special programs that run on a computer that allow it to function properly. The responsibilities contain recognizing input from the keyboard, keeping track of files and directories on the hard drive, sending output to the display screen, and handling input and output equipment like machines. Additionally, it provides a method for users to interact with the computer program by letting them control this through graphical user interfaces or command line line extrémité.

It monitors time and means used by numerous jobs or users. This produces deposits, traces and error information to help debugging or detecting problems. This manages the main memory, identifying what part of it is in use and who might be using it at any given moment. By using methods including paging and segmentation to permit programs to access large amounts of memory by tricking them in thinking that every one of the memory on the hard disk or perhaps RAM is definitely one continuous block, raising memory usage without requiring the computer to be restarted when a program needs more.

It handles the input and output of hardware devices, which include keyboards and mouses, besides making them compatible with the computer. In addition, it creates a data file directory framework for the computer and details the safe-keeping of data on long lasting non-volatile safe-keeping devices. Additionally, it helps to manage the computer’s memory, ensuring that it is shared among all processes, and that courses have no greater than processing power at any point soon enough.
