Operating systems are the underlying software that allows your computer to carry out its basic functions – from handling basic tasks like opening and closing files, to controlling the flow of information between programs. To keep your computer running smoothly, you need to keep your operating system up-to-date with the latest security patches and features.

What is an Operating System?

Operating systems are the foundation of modern computer systems. They provide an interface between the computer hardware and software, manage resources, and provide a platform for applications to run. The three most common types are:

Windows operating system: Windows is the most popular type of operating system. It is used on personal computers, laptops, tablet computers, smartphones, and other electronic devices.

Mac OS X: MacOS X is used on Apple products such as the iPhone, iPad, MacBooks, and iMacs.

Linux: Linux is used on servers, desktops, laptops, netbooks, embedded systems (such as automobiles), and many other devices.

Functions of an Operating System

An operating system is a software program that allows computer users to access their computers. This software helps users organize their files and programs, keep track of their online activity, and protect their data. Additionally, an operating system provides a platform for other applications to run.

The functions of an operating system include the following:

1. Registration and management of devices: An operating system registers devices (such as printers) with the computer, assigns them drivers, and manages access permissions. It also notifies the user when a new device is installed or when the driver for a device has been updated.

2. Storage allocation and management: An operating system allocates disk space to individual files and folders and manages how much space is available on the hard drive. It also moves files between disks if needed.

3. Management of software: An operating system notifies the user when new software is installed or when updated software is available for download. It also oversees allocating resources (such as CPU time) to individual programs.

4. Security: An operating system protects users’ information by verifying user identification, encrypting data, and blocking unauthorized access to files and folders.

Comparison of Different Operating Systems

An operating system is the set of software instructions that allow a computer to interact with its user. It manages the resources of the computer system, such as memory, storage, and CPU time, and provides a graphical interface and a means for users to access these resources. Operating systems are found on many devices including personal computers, phones, tablets, game consoles and embedded systems.


Operating system (OS) is the software that helps your computer to function. It’s responsible for handling all of the basic tasks of your computer, like starting up and shutdown, managing files, and running applications. Most importantly, an OS controls how your computer interacts with hardware. This means that it decides what actions your hardware can take and how it should respond.
