what are the two primary functions of an operating system?
1760
An operating system has three main functions: (1) manage the computer's resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software.

System software runs the hardware and computer system. The two main categories of system software are operating systems and utility software. Functions of system software are: The three major functions of system software are allocating system resources, monitoring system activities, and disk and file management.

An operating system is the whole package that manages our computers resources and lets us interact with it. There are two main parts to an operating system, the kernel and the user space. The kernel is the main core of an operating system. It talks directly to our hardware and manages our systems resources.

Kernel functions The main functions of the Kernel are the following: Manage RAM memory, so that all programs and running processes can work. Manage the processor time, which is used by running processes. Manage access and use of the different peripherals connected to the computer.

Answer: An operating system or OS is a software on the hard drive that enables the computer hardware to communicate and operate with the computer software. Without an operating system, a computer and software programs would be useless. It is like an interpreter between user and hardware.
