What is it called when a user makes a change to the master code in a Git repository?

Pull
Clone
Branch
Commit

The correct answer is: Commit

When a user makes a change to the master code in a Git repository, this process is referred to as a "commit." A commit in Git represents a snapshot of the changes made to files in the repository at a specific point in time. It allows the user to save their work, along with a message describing what changes were made. This serves both as a record of the project's evolution and as a way to provide a checkpoint to which the user can return if needed. Each commit is linked to a unique identifier (hash) and allows for tracking of changes over time. When a commit is made, the state of the repository is updated to include the new changes, enabling collaboration among multiple users and maintaining the integrity of the history of changes made to the codebase. In contrast, actions such as pulling, cloning, and branching serve different purposes in version control. Pulling is the process of fetching and integrating changes from a remote repository into the local repository. Cloning creates a copy of an entire repository, including its history, on a local machine. Branching involves creating a separate line of development from the main code, which allows for experimentation without affecting the master branch until those changes are ready to be merged.
