Linux
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
- CentOS Linux – a non-commercial derivative of RHEL, ideal for servers
- CloudLinux – a commercial derivative of RHEL, ideal for servers
- Debian – an open source distribution which can use either Linux of FreeBSD kernel
- RHEL – a business focused commercial distribution ideal for business and enterprise support
- Lenix – a project which intends to act as a continuation of CentOS
- Rocky Linux – a project which intends to act as a continuation of CentOS
- Ubuntu Linux – a mostly-free distribution based around Debian with popularity on desktop and amongst developers
