Distribution “Distro” Components
- Linux kernel
- Supporting software and libraries
- Configuration files
Kernel
- Low level computer program which functions as the bridge between the user and the computer’s resources
- Translates software commands into hardware-specific requests

Hardware Comparability List (HCL)
Lists tested, compatible, and sometimes incompatible hardware devices fora particular distribution
Recommended Requirements
Hardware that one should have in order to fully maximize a system’s potential
Minimum System Requirements
Lowest possible hardware spec that your pc should have to boot successfully and use with basic functionality
What OS dominates the server space
- Linux has about 70% of the market share
Cloud Computing
On-demand availability of computer system resources, especially data, storage, and computing power, without direct active management by the user
