This resource will explain how operating systems work, and note the differences between the Microsoft Windows, Mac and Linux operating systems. An operating system is a program that acts as an interface between the computer user and computer hardware, and controls the execution of programs. 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. 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. In the image above the User interfaces with the System & Application software. The System & Application software interfaces with the Operating System. The Operating system interfaces with the Hardware. Each of these interfaces are two way transactions with each sending and receiving data. Types of operating systemsOperating systems usually come pre-loaded on any computer you buy. Most individuals use the operating system that already comes with their computer however it is possible to upgrade or change the initial operating system to suit your preference. Different operating systems will work in different ways. They may appear visually different, have different terms for common functions and organise programs in different ways. Do not be alarmed if you find yourself using a computer at university that you are unfamiliar with – a bit of practice and you’ll be well on your way! There are many operating systems that are available however the three most common operating systems are Microsoft’s Windows, Apple’s macOS and Linux. In the table below, we will outline a few of the key differences between each system.
