The type of programs enable a user to perform his or job.
Operating System
Main collection of programs that manage and control a computer’s activities.
GUI
An environment in which users issue commands by selection icons, buttons, and other images.
Command-line-interface
An environment in which users issue commands by typing them on the keyboard.

Techniques that increase system efficiency.
Multiprogramming
Multitasking with a multiuser operating system.
Multithreading
A type of operating system with the ability to process multiple sequences of instructions within a program at one time.
Thread
A sequence of instructions within a program.
Coprocessing
Utilizes special-purpose processors to assist the CPU with specialized chores.
Parallel processing
Involves using two or more CPUs in a computer system to work more efficiently.
