Linux Distributions

A Linux distribution (distro) is a curated combination: Linux kernel, init system, C library (usually glibc or musl), package manager, default services, and often a desktop environment. Distros differ by release model (rolling vs fixed), default packaging format, security updates, and target audience.

Beginners often start with Ubuntu LTS or Linux Mint for hardware support and documentation. If you want production-parity skills for enterprise Linux, practice on Fedora or an Alma/Rocky VM. For learning fundamentals, any mainstream distro with bash and coreutils is enough — concepts of users, packages, and services transfer.
