Linux Distribution

Definitions

A packaged operating system built around the Linux kernel plus a curated set of userland tools, repositories, defaults, and maintenance policies. Different distributions optimize for different tradeoffs such as stability, bleeding-edge packages, or minimalism.
In plain English: A packaged form of Linux with its own tools, repositories, and release style.
Example: "The product had to support more than one Linux distribution because enterprise customers standardized on different vendor stacks."
