How Git Actually Works

How does Git actually work under the hood? See what Git really saves when you commit: blobs, trees, commits, hashes and branches. ⏺︎ Related video ▶︎ What Really Happens When You Run Python Code? 🔗    • What Really Happens When You Run a Code?   This is not a Git commands tutorial. We type only a few commands and watch what each one does inside the hidden .git folder, using real hashes from a real repository. No Git experience needed. ⏺︎ What you'll learn • What a hash is, and why changing one letter changes the whole fingerprint • How Git stores files by their hash, and why identical content is stored once • What blobs, trees and commits are • What the staging area really does • Why Git stores snapshots, not changes, without copying unchanged files • Why changing old history changes every later commit ID • Why a Git branch is a tiny 41-byte file • What HEAD is, and what happens when you switch branches • A final challenge: how many objects does one commit create? ⏺︎ Chapters 00:00 How does Git keep every version? 00:26 How Git actually works under the hood 01:13 Part 1: what a hash is 02:50 How Git stores files by their hash 04:51 Part 2: Git blobs, trees and commits 06:15 Why Git stores snapshots, not changes 07:57 Part 3: what a Git branch really is 09:05 What is Git HEAD? 09:57 What does one Git commit create? 10:56 Blob vs tree vs commit vs branch 11:29 Thanks for watching ⊙ About Brain Link ⏺︎ Brain Link is an educational platform dedicated to exploring the science, mathematics, and engineering behind Artificial Intelligence and modern computing. ⏺︎ We believe in understanding, not memorizing.
