Tracks changes, enables branching and collaboration.
Git is a distributed version control system recording snapshots (commits). Commands: init, add, commit, branch, merge, rebase, pull, push, log, diff. Branching supports parallel work; remote hosts like GitHub enable collaboration and pull requests. Good commits are small and described clearly.
git switch -c feature creates a branch to develop safely.
Version control records every change to code, so teams can work in parallel and recover from mistakes.

A snapshot of the changed files with a message describing the change and a link to the previous version.
A situation where two branches change the same lines, so the person merging must choose the correct result.
Typical applications include tracking changes to a control program used by several engineers, creating a branch to test a new feature safely and reverting to a working version after a faulty update.
Study "Pseudocode and flowcharts" first (topic 12 of 104 in Software & Computing). It covers the groundwork this topic builds on.

The next topic is "Command line basics", which builds directly on this one.
It is classed as Beginner in Software & Computing (topic 13 of 104). It is an entry-level topic. It relies only on basic school mathematics and the ideas introduced earlier in this discipline.
