Course description

Linux is an open-source, Unix-like operating system kernel that serves as the foundation for many operating systems, collectively called Linux distributions. Originally developed by Linus Torvalds in 1991, Linux has grown to become a powerful and versatile platform used in everything from servers and desktops to embedded systems and mobile devices.

Linux distributions, such as Ubuntu, Fedora, and Debian, cater to different user needs, offering various combinations of user interfaces, software packages, and support. Linux is known for its stability, security, and flexibility, making it a popular choice for developers, system administrators, and tech enthusiasts.

The operating system supports a variety of file systems, scripting languages, and development tools, fostering a robust environment for programming and system management. Users can interact with Linux through graphical user interfaces (GUIs) or the command line, which provides powerful control over system functions.

Linux is widely adopted in the server industry due to its performance and low cost, being the backbone of web servers, cloud infrastructure, and supercomputers. The open-source nature of Linux encourages community collaboration and customization, giving users the freedom to modify and share code.

Key features of Linux include multitasking, multi-user capabilities, and extensive hardware support. With a strong focus on security, Linux provides tools for permissions, firewalls, and encryption. The ecosystem is enriched by a vast array of distributions tailored for various purposes, from lightweight versions for older hardware to robust ones for enterprise environments.
