3. Version Control System?
Version control systems are a category of
software tools that help a software team manage
changes to:
 Source code over time
 Track of every modification
 Clock and compare earlier versions
 Minimizing disruption

4. History
The history of version control tools can be divided
into three generations.
Genertaion Networking Operations Concurrency Example
First None One File at a
time
Locks RCS, SCCS
Second Centralized Multi-file Merge

CVS,
SourceSafe,
Subversion
Third Distributed Change sets Commit

5. Types
 Centralized version control system(CVCS)
 Distributed/Decentralized version control
system(DVCS)

7. Centralized version control system?
A centralized version control system means that the
version history is stored in a central server.
Example: SVN

8. Distributed/Decentralized version control system?
This is a form of version control where the complete codebase –
including its full history – is mirrored on every developer's computer.
Example: Git
