Linux Distributions Overview
Linux is an open-source operating system kernel, and a Linux distribution (distro) is a complete operating system built around the Linux kernel, including system software, package managers, and desktop environments.
What is a Linux Distribution?
A Linux distribution consists of:
- Linux kernel - Core of the OS
- System utilities - GNU tools and other system software
- Package manager - Software installation/management system
- Desktop environment - Graphical user interface (optional)
- Pre-installed software - Applications and tools

Getting Started
Try Before Installing
Use Live USB to test distributions without installation:
- Download ISO file
- Create bootable USB (use Etcher, Rufus, or dd)
- Boot from USB
- Try distribution without installing
Dual Boot
Keep Windows and Linux on same computer:
- Use separate partitions
- GRUB bootloader lets you choose OS at startup
Virtual Machine
Test in a VM first:
- Use VirtualBox or VMware
- Safe way to learn
- No risk to existing OS
Resources
- DistroWatch - Distribution news and rankings
- Ubuntu Documentation
- Arch Wiki - Excellent resource for all distros
- Linux Journey - Learn Linux basics
- r/linux - Linux community
