Main Branch: The primary branch of a repository, holding the stable, accepted code. Usually named main (older projects use master).
Example
Your team protects the main branch, so changes can only reach it through an approved Pull Request.
Why Main Branch matters for IT interns
Never push untested work directly to main — most teams don’t allow it anyway.
Where you will hear it
You will use this term almost daily when working on code with a team, through Git, GitHub, or a similar tool. If someone uses it and you are not sure what they mean in your project, it is completely fine to ask; every team uses terms a little differently.
