2. VERSION CONTROL SYSTEM - DEFINATION
What is version control, and why should we care?
● Version control is a system that records changes to a file or set of files
over time so that you can recall specific versions later.
● The files may be text file to graphic design files.
● It allows you to revert files back to a previous state, revert the entire
project back to a previous state, compare changes over time, see who last
modified something that might be causing a problem, who introduced an
issue and when, and more.
● Since most software projects are done collabratively by a group, it is
necessory to learn and use version control system.

3. TYPES OF VERSION CONTROL SYSTEMS
● LOCAL VERSION CONTROL SYSTEMS
● CENTRALISED VERSION CONTROL SYSTEMS
● DISTRIBUTED VERSION CONTROL SYSTEMS

4. LOCAL VERSION CONTROL SYSTEMS

5. CENTRALISED VERSION CONTROL SYSTEM

6. DISTRIBUTED VERSION CONTROL SYSTEM

7. VERSION CONTROL SYSTEM – GLOSSARY
Repository
The repository is where files' current and historical data are stored, often
on a server
Checkout
To check out is to create a local working copy from the repository. A user
may specify a specific revision or obtain the latest.
Change
A change (or diff, or delta) represents a specific modification to a
document under version control.
Revision
Also version: is the state at a point in time (of the entire tree) in the
repository.
