3. Version Control System
“A version control system (sometimes called revision
control) is a tool that lets you track the history and
attribution of your project files over time (stored in a
repository), and which helps the developers in the team to
work together. Modern version control systems help them
work simultaneously, in a non-blocking way, by giving
each developer his or her own sandbox, preventing their
work in progress from conflicting, and all the while
providing a mechanism to merge changes and
synchronize work.”
“Mastering Git.”

5. What is GIT?
Git is Distributed Version Control System
“Distributed means that there is no main server and all
of the full history of the project is available once you
cloned the project”

6. A Brief History
• In 2002, the Linux kernel project bega using a DVCS
calld BitKeeper.
• In 2005, the commercial company that developed
BitKeeper broke down, and the tool’s free-of-charge
status was revoked.
• This prompted the Linux development community
(and in particular Linux Trovalds, the creator of Linux)
to develop their own tool - GIT

7. First of all, definitions
• Working tree
A directory in your filesystem that is
associated with a repository, containing files &
sub-directories
• Repository
A collection of commits & branches, saved
in the .git directory
• Commit
A Snapshot of your working tree at a certain
point in time, identified by a revision number.
• HEAD
The name for the commit thats currently
checked out in.

8. GIT
• You can imagine git as something that
sits on top of your file system and
manipulates files.
• This “something” is a tree structure
where each commit creates a new
node in that tree.
• Nearly all git commands actually serve
to navigate on this tree and to
manipulate it accordingly.
