Explain these Git operations and their purpose: commit, branch, merge. How do they support team collaboration?

Solution

  1. 1
    Step 1: Commit: saves a snapshot of your changes with a message describing what you changed and why. Creates a checkpoint you can return to.
  2. 2
    Step 2: Branch: creates a separate line of development. A developer can work on a new feature without affecting the main codebase.
  3. 3
    Step 3: Merge: combines changes from one branch into another. Once a feature is complete and tested, it is merged into the main branch. This allows multiple developers to work simultaneously without conflicts.

Answer

Commit: save changes. Branch: work independently. Merge: combine changes. Together they enable parallel development without interference.
Branching and merging are the core of team collaboration in version control. They allow multiple features to be developed in parallel and integrated when ready.

About Version Control

A system that records changes to files over time so you can recall specific versions, compare changes, and collaborate without overwriting each other's work. Git is the most widely used version control system, using concepts like commits (snapshots), branches (parallel lines of development), and merges (combining changes).
