What is Git?

Git is a Distributed Version Control System (DVCS) used to:

• Track changes in source code
• Collaborate with multiple developers
• Maintain complete history of a project
• Work offline and merge changes later

Each developer has:

• A full copy of the repository
• Full history (not dependent on a central server)

Why Git is Needed

Problems without version control:

• Code overwritten by others
• No history of changes
• Hard to rollback bugs
• Manual backups

Git solves:

• Version tracking
• Collaboration
• Branching and merging
• Rollback and recovery
