Linux is commonly used to refer to an operating system distribution based on the Linux kernel, the kernel being the core interface between the hardware and software. Similar but different to Unix, the Linux kernel is open source and free software (but the distributions which package it are not always). Linux has traditionally been the OS of choice for Open Source software such as C, perl, php, python.
Popular Linux distributions include:
- AlmaLinux – a project which intends to act as a continuation of CentOS
- Arch Linux – a minimalist distribution which results in high efficiency, ideal for server
