The Brain of the Computer: A Guide to Operating Systems

An operating system (OS) is the most important software on a computer. It manages all of the computer’s hardware and software resources and provides the basic functions for a user to interact with the device. Without an operating system, a computer is just a collection of electronic parts. It performs a wide range of essential tasks, including managing memory, controlling input and output devices, handling files, and running applications. From the user-friendly interfaces of Windows and macOS to the open-source flexibility of Linux, each operating system provides a unique environment for the user, acting as the crucial link between the hardware and the software.
