System Software: System software is a type of computer program that is designed to run a computer’s hardware and application programs it controls a computer’s internal functioning, chiefly through an operating system. It also controls peripherals devices such as monitors, printers, and storage devices. 2. Operating System: An operating system or OS is system software that manages computer hardware, and software resources, and provides common services for computer programs. All operating systems are system software. Every desktop computer, tablet, and smartphone includes an operating system that provides basic functionality for the device. Difference between System Software and Operating System :
An operating system acts as an intermediary between the user of a computer and computer hardware. The purpose of an operating system is to provide an environment in which a user can execute programs conveniently and efficiently. An operating system is a software that manages computer hardware. The hardware must provide appropriate mechanisms to ensure the correct operation of the computer system and to prevent user programs from interfering with the proper operation of the system. Operating System – Definition:
Functions of Operating system – Operating system performs four functions:
Major Functionalities of Operating System:
The process operating system as User Interface:
Every general-purpose computer consists of the hardware, operating system, system programs, and application programs. The hardware consists of memory, CPU, ALU, and I/O devices, peripheral devices, and storage devices. System program consists of compilers, loaders, editors, OS, etc. The application program consists of business programs, database programs. Fig1: Conceptual view of a computer system Every computer must have an operating system to run other programs. The operating system coordinates the use of the hardware among the various system programs and application programs for various users. It simply provides an environment within which other programs can do useful work. The operating system is a set of special programs that run on a computer system that allows it to work properly. It performs basic tasks such as recognizing input from the keyboard, keeping track of files and directories on the disk, sending output to the display screen, and controlling peripheral devices.
The Operating system must support the following tasks. The tasks are:
I/O System Management –
Drivers for specific hardware devices. Assembler – Compiler – Loader – History of Operating system –
Types of Operating System –
Examples of Operating System are –
