Linux

Linux is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released in 1991 by Linus Torvalds. It is widely used in servers, embedded systems, supercomputers, and increasingly in desktop environments, known for its stability, security, and flexibility.

Also known as: GNU/Linux, Linux OS, Linux Distro, Linux Kernel, Unix-like OS

Why learn Linux?
