COMPUTER FUNDAMENTALS

Detailed explanation-1: -The operating system (OS) manages all of the software and hardware on the computer. It performs basic tasks such as file, memory and process management, handling input and output, and controlling peripheral devices such as disk drives and printers.

Detailed explanation-2: -operating system (OS), program that manages a computer’s resources, especially the allocation of those resources among other programs. Typical resources include the central processing unit (CPU), computer memory, file storage, input/output (I/O) devices, and network connections.

Detailed explanation-3: -The operating system must manage the use of hardware resources so that software can complete its tasks. Each program running on a computer is known as a process. The OS manages how software processes share the system’s resources. For example, most software needs to save data to a storage device, such as a hard disk.

Detailed explanation-4: -An operating system provides three essential capabilities: It offers a UI through a CLI or GUI; it launches and manages the application execution; and it identifies and exposes system hardware resources to those applications–typically, through a standardized API.
