The main functions of an operating system

What are the main components of OS? 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. 5 functions of operating system explained What are the main functions of operating systems? Image: Source: UGC. Computers and portable devices like tablets or smartphones work with the help of different types of OS. Windows, Linux, Mac OS, Android are the most widely spread and popular types. They are different in certain details but, in general, they perform 5 main functions. 1.4. Basic Operating System Concepts - Understanding the The operating system must fulfill two main objectives: Interact with the hardware components, servicing all low-level programmable elements included in the hardware platform. Provide an execution environment to the applications that run on the computer system (the so-called user programs). Operating Systems

In simplest terms, an operating system is a collection of programs that manage a computer system's internal workings— its memory, processors, devices, and file system. Mainframe operating systems are sophisticated products with substantially different characteristics and purposes. Operating systems are designed to make the best use of the computer's various resources, and ensure that the

Computer Basics: Understanding Operating Systems The operating system's job. Your computer's operating system (OS) manages all of the software and hardware on the computer.Most of the time, there are several different computer programs running at the same time, and they all need to access your computer's central processing unit (CPU), memory, and storage.The operating system coordinates all of this to make sure each program gets what it needs.

3.4.1 Shared-Memory Systems. In general the memory to be shared in a shared-memory system is initially within the address space of a particular process, which needs to make system calls in order to make that memory publicly available to one or more other processes.
