Definition of Operating System
Operating system is a set of programs that coordinates all the activities among computer hardware devices. It also contains instructions that allow users to run application software. When a user starts a computer, portions of the operating system (OS) load into memory from the computer’s hard disk. It remains in memory while the computer is on. The operating system provides a means for users to communicate with other software. It is the operating system that makes the computer understand the user’s instructions and commands. It is the life-wire of a computer system. It does the loading and schedule of all activities going on in a computer system.
For users to be able to interact with the computer machine, the operating system provides the user with what is called user interface (UI)
The Meaning of User Interface
What is user interface (UI)? This is the space through which interactions between humans and machines occur. The goal of UI is to allow effective operation of the computer machine.
Types of User Interface
(i) Command based interface: In command-based interface, lines of command are used to instruct or communicate with the computer system.
(ii) Graphical User Interface (GUI): With graphical user interface, you interact with the software using text, graphics, and visual images such as icons. An icon is a small image that represents a program, an instruction, or some other object on the computer screen.
