Managing hardware on the computer
Controlling the access that application program has to the CPU
Provides an interface for user to interact with computer
Answer is Wrong!
Answer is Right!
The correct answer is D.
An operating system (OS) is a system software that manages computer hardware and software resources and provides common services for computer programs. The operating system is a vital part of the system software in a computer system.
The operating system performs the following tasks:
- Manages hardware on the computer. The operating system manages the computer’s hardware resources, such as the CPU, memory, disk, and network. It allocates these resources to programs as needed.
- Controls the access that application program has to the CPU. The operating system ensures that only one program is using the CPU at a time. This prevents programs from interfering with each other.
- Performs housekeeping task like file compression and disk defragmentation. The operating system performs tasks that keep the computer running smoothly, such as file compression and disk defragmentation.
- Provides an interface for user to interact with computer. The operating system provides a user interface that allows users to interact with the computer. This interface can be a command-line interface, a graphical user interface, or a touch-screen interface.
Option D is incorrect because it is not a task performed by the operating system. The operating system does not provide an interface for users to interact with the computer. This interface is provided by a program called a shell. The shell is a program that allows users to run commands and interact with the operating system.
