Introduction to Operating Systems
An Operating System (OS) is essential system software that manages hardware resources, memory, files, and applications, while providing an interface between the user and the computer.
Two of the most widely used operating systems are Linux and Windows. While both serve similar purposes, they differ significantly in terms of architecture, security, performance, customization, and licensing.
Linux vs Windows – Overview
What is Linux?
Linux is an open-source operating system based on Unix. It is developed by a global community and distributed through versions known as distributions (distros) like Ubuntu, Debian, Fedora, and Red Hat.
What is Windows?
Windows is a proprietary operating system developed by Microsoft. It is widely used for personal computing, enterprise environments, and gaming, with versions like Windows 10, Windows 11, and Windows Server.
