22.-+Operative+Systems

‍The most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs. Operating systems perform basic tasks, such as recognizing input from the keybboard, sending output to the display screen, keeping tracj of files and directories on the disk, and controllong peripheral devices such as disk drives and printers. ‍An operative system, or OS, is a software program that enables the computer hardware to communicate and operate with the computer software. Without a computer operating system, a computer would be useless. ‍Operative systrm types: As computers have progressed and developed so have the operating system. Below is a basic list of the diferent operating systems and a few examples of operating systems that fall into each of the categories. GUI: Short for graphival user interface, a GUI operating system contains graphics and icons and is commonly navigated by using a computer mouse. ‍Multiuser: alowws for multiple users to use the same computer at the same time and different times. ‍Multiprocessing: capabl e of supporting and utilizing more than one computer processor. ‍Multitasking :An operating system that is capable of allowing multiple software processes to run at the same time.

The application programs must be written to run on top of a particular operating system. Your choice of operating system, therefore, determines to a great extent the applications you can run. For [|PCs], the most popular operating systems are DOS, [|OS/2] , and [|Windows] , but others are available, such as [|Linux] .For large systems, the operating system has even greater responsibilities and powers. It is like a traffic cop -- it makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system.  [][] [[image:operative_system]]
