One operating system might be better suited to some computing tasks than others. The most popular are: launch programs, manage files, get help, customize the user interface, and configure equipment.

They are typically accessed by using a GUI, such as the familiar Windows desktop. Many operating systems provide helpful tools, called operating system utilities, that you can use to control and customize your computer equipment and work environment. Other parts of OS, such as customization utilities, are loaded into RAM as they are needed. The kernel always stays in RAM all the time your computer is on. This core part of OS called the kernelprovides the most essential operating system services, such as memory management and file access. The operating system’s small bootstrap program is stored in ROM and supplies the instructions needed to load the operating system’s core into memory when the system boots. A command-line interface requires you to memorize and type commands.įor nearly all PCs, servers, workstations, mainframes, and supercomputers, the operating system program is quite large, so most of it is stored on a hard disk. A graphical user interface (GUI) features menus and icons that you can manipulate with the click of a mouse.

It also includes software elements, such as menus and toolbar buttons. Your computer’s user interface includes a display device, mouse, and keyboard that allow you to view and manipulate your computer environment. A user interface can be definedas the combination of hardware and software that helps people and computers communicate with each other.

Establish basic elements of the user interface. OS uses ‘buffers’ to collect and hold data while the computer is busy with other tasks.

OS communicates with device driver software so that data can travel smoothlybetween the computer and these peripheral resources. Ensure that input and output proceed in an orderly manner. It remembers the names and locations of all your files and keeps track of empty spaces where new files can be stored. OS stores and retrieves files from your disks and CDs. A computer can take advantage of performance-enhancing technologies such as multitasking, multithreading,multiprocessing,dual coreormultiple processors. OS must ensur e that each activity “process” receives its share of microprocessor cycles. Many activities – called “processes” – compete for the attention of your computer’s microprocessor. Every cycle of a computer’s microprocessor is a resource for accomplishing tasks. The operating system also controls the microprocessor – just at a slightly higher level. If an OS falls down on the job and fails to protect each program’s memory area, data can get corrupted, programs can “crash”, and your computer displays error messages. When multiple programs are running, the OS must ensurethat instructions and data from one area of memory do not “leak” into an area allocated to another program. When you want to run more than one program at a time, the OS has to allocate specific areas of memory for each program.

A microprocessor works with data and executes instructions stored in RAM – one of your computer’s most important resources. OS is itself a program, so it requires RAM space too. OS allocates a specific area of RAM for each program that is open and running.

Operating system manages different tasks: RAM, storage space, and peripherals are also resources. For example, the processor is a resource. The term resource refers to any component that is required to perform work. The operating system interactswith application software, device drivers, and hardware to manage a computer’s resources. It is one of the factors that determine your computer compatibilityand platform. An operating system (abbreviated OS) is a type of system software that acts as a mast controller for all the activities that take place within a computer system.
