Git Intro and Installation on Ubuntu in 2 simple steps

What is a version control system? 

VCS or Version Control System is similar to history which records events happened on a particular date (June 29, 2007 - First iPhone launch) where as VCS record events happened on a particular revision/commit (commit id - files updated).

VCS Tools:

• Git
• Subversion (SVN)
• Concurrent Versions System (CVS)

Distributed VCS

When you checkout a repository  instead of getting only the tip of the source it actually clones the entire repository.

So basically each copy of repo itself a backup of central repository.

In case of failure of central repo you can create a new repo a push your copy to the central repo. (which is considering you are in sync with central repo)

What is Git ?

Git is

• Distributed version control system
