Introduction To Operating System
Operating System Functions
Important Features Of The Operating System.
Types Of Operating System

Welcome to learn computer science online dot com and in this video we are going to discuss what is an operating systems , functions, types, and, its importance in computer architecture and organization.
Let us start with a simple brief introduction to the operating system.
An operating system is a group of software specially designed to help the user to manage and operate the computer system.
In other words , the operating system is a type of system software that works as an interface between the system user and the computer hardware.
The Operating system is an essential component of every computer system.
It is a type of system software used by the computer system itself to manage and operate the system.
It also helps the computer user to interact with various hardware components that are either connected or part of the computer system.
An operating system performs some of the most important functions that are crucial for the operation , performance, and the safety of the computer system.
The resource management, is one such important function performed by the operating system.

In this video I show the most used Operating Systems on consumer personal computers and mobile devices from 1981 to 2025, reflecting the shift from PCs to mobile platforms.

Windows versions are represented by major updates, while Macintosh operating systems are grouped under Classic Mac OS, OS X, and macOS without subversion names.

Regarding Linux, technically, many operating systems in my chart are based on the Linux kernel, but I have listed them under their original names, as they deserve recognition as standalone brands in the OS landscape. The Linux category aggregates data from widely known distributions such as Ubuntu, Debian, Fedora etc.

For the first 20 years, estimates are based on PC sales by specific manufacturers, combined with survey data on how long users kept their devices before upgrading. More recent years primarily use data from internet providers and web traffic reports. That's why I have included only operating systems on consumer PCs and mobile phones, as personal gadgets, home devices, and web servers have a very small footprint in web traffic data to estimate their popularity.
