What is the main difference between tags and branches in the Git version control system?.

The main difference between tags and branches in Git lies in their purpose and behavior:

• Branches are movable pointers to commits. A branch changes as you add new commits. Branches are used for developing new features, fixing bugs, etc.

• Tags are fixed pointers to specific commits. Tags are usually used to mark releases or important points in the project's history. They do not change after creation.

Example:

• The develop branch will move forward with each new commit.
• The v1.0 tag always points to a specific commit corresponding to version 1.0.

Thus, branches are dynamic lines of development, while tags are static labels.
