Spent some time messing with a CH341A programmer and SOIC8 clip today.
Read a BIOS chip directly from the board, dumped the firmware, extracted .efi / .bin files, and browsed through some assembly.
Nothing huge, just fun low-level curiosity.
๐ง TL;DR
Directory = technical term (used in terminal, programming)
Folder = friendly visual term (used in GUI)
๐ฌ They refer to the same thing, just in different contexts.
๐น LTS (Long Term Support)
Released every 2 years (e.g. 20.04, 22.04, 24.04)
Supported for 5 years (or up to 10 with Extended Security Maintenance)
Best for servers and long-term setups
Ubuntu uses a version format like:
YY.MM โ Year.Month of release
Examples:
22.04 โ April 2022
24.04 โ April 2024
Ubuntu releases twice a year:
1. April (.04)
2. October (.10)
๐ง 1. What Are Linux Distros?
A Linux distribution (distro) = Linux kernel + tools + package manager + user interface.
Each distro is a complete OS tailored for different users.
Examples:
Ubuntu โ beginner-friendly
Arch โ minimal and DIY
Fedora โ cutting-edge devs
Debian โ stability
Kali โ ethical hacking
๐ก Distros share the Linux base but differ in goals, tools, and community.
