تعريف işletim dizgesi في التركية الإنجليزية القاموس.

(Bilgisayar) operating system

The software responsible for allocating system resources,including memory, processor time, disk space, and peripheral devices such as printers, modems, and the monitor All application programs use the OS to gain access to these system resources as they are needed The OS is the first program loaded into the computer as it boots, and it remains in memory at all times thereafter DOS,OS/2,Win 9x&2000, Unix and Sun are all operating systems

An operating system (sometimes abbreviated as OS) is the program that, after being initially loaded into the computer, manages all the other programs in a computer The other programs are called applications or application programs Today, most users interact with the operating system through a graphical user interface (GUI)

The program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer The other programs are called applications or application programs The application programs make use of the operating system by making requests for services through a defined application program interface (API) In addition, users can interact directly with the operating system through a user interface such as a command language or a graphical user interface (GUI)

apparatus which enables the operation of a device; main program in a computer which is responsible for the allocation of resources to its various procedures

The special software required to make a computer work It provides the link between the user and the hardware Popular operating systems include DOS, MacOS, VMS, VM, MVS, UNIX, and OS/2 (Note that "Windows 3 x" is not an operating system as such, since it must have DOS to work, while Windows NT and Windows 98 are operating systems )

The program that controls the camera's or computer's hardware

System software that controls a computer and its peripherals Modern operating systems such as Windows 95 and NT handle many of a computer's basic functions /\

Programs which run the computer, and without which the computer would not work The OS allows the programs we use to run The various Windows, Mac System7 and its successors and the various OS2 products may all be considered operating systems

Collection of programs that supervises the execution of other programs and the management of computer resources An operating system provides an orderly input/output environment between the computer and its peripheral devices It enables user-written programs to execute safely An operating system standardizes the use of computer resources for the programs running under it

An operating system (OS) is a matched set of programs (including the kernel) that enable other programs to run on your computer Modern operating systems often include a "window system" to organize graphical images and controls on your screen An OS includes other programs such as "daemons", which monitor the system for interesting events and respond to them, and "utilities" which you can use to control what the OS does

A big complicated computer program that lets multiple simultaneously executing big complicated computer programs coexist peacefully on one physical computer The operating system is also responsible for hiding the details of the computer hardware from the application programmers, e g , letting a programmer say "I want to write ABC into a file named XYZ" without the programmer having to know how many disk drives the computer has or what company manufactured those drives Examples of operating systems are Unix and Windows NT Examples of things that try to be operating systems but mostly fail to fulfill the "coexist peacefully" condition are Windows and the Macintosh OS

Software that shares a computer system's resources (processor, memory, disk space, network bandwidth, and so on) between users and the application programs they run Controls access to the system to provide security See also kernel, system program, application program

The system software that manages a computer's resources, performing basic tasks such as allocating memory and allowing computer components to communicate

A master control program that runs the computer It provides the user interface and routines that let the user load and run software

The operating system of a computer is its most basic program, which it needs in order to function and run other programs. Software designed to control the hardware of a specific data-processing system in order to allow users and application programs to make use of it. a system in a computer that helps all the programs in it to work together. Software that controls the operation of a computer, directs the input and output of data, keeps track of files, and controls the processing of computer programs. Its roles include managing the functioning of the computer hardware, running the applications programs, serving as an interface between the computer and the user, and allocating computer resources to various functions. When several jobs reside in the computer simultaneously and share resources (multitasking), the OS allocates fixed amounts of CPU time and memory in turn or allows one job to read data while another writes to a printer and still another performs computations. Through a process called time-sharing, a large computer can handle interaction with hundreds of users simultaneously, giving each the perception of being the sole user. Modern computer operating systems are becoming increasingly machine-independent, capable of running on any hardware platform; a widely used platform-independent operating system in use today on mainframe computers is UNIX. Most personal computers run on Microsoft's Windows operating system, which grew out of and eventually replaced MS-DOS. See also Linux

A program that manages all other programs in a computer, such as Windows or unix

The operating system is a program specially written to manage the operations of the computer The operating system is the interface between you, the software you use and the computer hardware Windows 98 is an operating system, as is UNIX or MS-DOS Apple Macintosh has its own operating system

A program that provides a user interface and an application interface (which makes it possible for application programs to run) and manages computer system resources

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 keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers For large systems, the operating system has even greater r

A collection of programs which, together, manage all the basic functions of a computer The operating system runs other programs (such as a word processor or graphics editor), manages the storage of your own documents, and coordinates the functions of the computer itself and all the devices connected to the computer Windows Me, Mac OS and Linux are three examples of operating systems A program written to work under one operating system will not work on another operating system (a different version must be written for each operating system - such as Microsoft Office for Windows and Office for the Mac )
