Git Interview Question: Difference between a Commit and a Branch in Git

In Git, a commit represents a snapshot of your repository at a specific point in time. It is like a save point that records the changes made to your files. Each commit has a unique identifier and includes the author, timestamp, and a message describing the changes.

On the other hand, a branch in Git is a pointer to a specific commit. It allows you to work on different versions of your code in parallel. When you create a branch, you are essentially creating a new path for your commits to follow without affecting the main codebase.

So, the main difference between a commit and a branch in Git is that a commit represents a specific change to your codebase, while a branch is a separate line of development that may contain multiple commits.
