Computer Tutorials: How an OS works

The Operating System of a computer plays an integral role in carrying out different computing tasks simultaneously. If the CPU is referred as the “brain of the computer” then, the OS is definitely the “soul of the system”. It integrates the hardware and software parts of your computer to be able to establish a smooth flow in performing computer applications and user interactions. Advanced OS now even have the capability to adapt to the needs of the users that change over time. But how does it do all of these?

Basically, an OS is assigned to do two tasks. First, it controls and manages the computer resources (e.g. memory, CPU, storage, hardware, device drivers, applications and input and output devices) and designates it to the applications that need it to run properly. It does this without compromising other ongoing applications. It also makes sure that the computer has fully achieved its best performing capacity by utilizing the hardware and software resources efficiently. Its second task is to ensure stability in the system’s total operations despite hardware changes and computer upgrades. It provides API (Application Program Interface) stability and consistency. This allows users to modify or write programs on a computer without having to trouble themselves from the problem of being able to run it on a separate desktop or laptop. So that even though the computer hardware undergoes modifications and updates, there is an assurance that the applications would continually to run.

Understanding how the Operating system works is a key element in modifying its behavior so as to meet your varied computing needs and be able to use this to your advantage.
