- Basic function
THE PRIMARY FUNCTION OF AN OPERATING SYSTEM ARE
1. Translator, 2. manager, 3. organizer
OPERATING SYSTEM
1. As translator: it interpret what is typed on the keyboard to the computer. Or it interprets user command usually inhuman languages to machine code.
2. As a manager: it manages the operation of all the component attached to CPU e.g the printer, mouse, scanner, CD etc it scheduled operation among all the resources.
3. As organizer: it organized the files and the program in the computer system. Or it keeps what you stored on diskette.
BASIC FUNCTION OF AN OPERATING SYSTEM
The function may include;
- It protects the hardware, software and data from improper use
- Provision of error correction routine. (carry out correction).
- The scheduling and loading of program or subprogram in other to provide continue sequence of process, or to provide appropriate responses to events.
- Control over hardware resource e.g. control over the selecting and operation of devices used for input or output storage.
- Communication between computer and operator usually by means of the console or typewriters. The operators communicates with the operating system by means of a JCL (job control language) which is executed by an interactive command interpreter.
- Passing of control from one storage (one program) to another under a system priority, when more the one application program occupies the main storage.
