What is Git ?
Git is a distributed Revision Control System. Such systems helps developers safely manage, track, and restore changes in code during software development. When more than one developer is involved, revision control systems provide a workflow for cooperative development and reconciliation of conflicting contributions.
Revision System Control
Revision System Control (also called Version Control) is a tool that helps developers track changes in their code over time.
Why it is needed
- When working on a project, code changes often:
- Bugs are fixed
- New features are added
- Code is improved
- Sometimes a change breaks the program
- Revision control lets you go back to an earlier working version and fix the problem
Problems without revision control
- You may not know when or where a bug was introduced
- Manual backups (copy-paste folders) are messy and hard to manage
- Comparing old and new code becomes difficult
- Tracking who changed what is almost impossible
What revision control does
- Saves a history of changes instead of full copies
- Allows you to:
- See what changed
- See who made the change
- Restore older versions of code
-Saves disk space and time
-Makes debugging easier
Importance in teamwork and open-source projects
- Shows who contributed each part of the code
- Helps identify experts for specific features
- Tracks legal ownership of code to avoid license problems
- Makes collaboration safer and more organized
