2. Why is Git Around?
Git is a distributed version control system used in software development.
It allows multiple developers to collaborate on a project by tracking
changes to the codebase, managing different branches, and facilitating
efficient teamwork.
The history of version control systems (VCS) is closely tied to the
evolution of software development practices. Here is a brief overview of
the key milestones in the history of version control.
1. Local Version Control Systems (LVCS)(1970s)
2. Centralized Version Control Systems (CVCS)(1980s)
3. Distributed Version Control Systems (DVCS)(2000s)
4. Git's Emergence(Mid-2000s Onward)
3. Here's a brief overview…..
1. Local Version Control System (LVCS): Developers manually kept
different versions of files on their local machines.
2. Centralized Version Control System (CVCS): Introduced a central
server to store versioned files, but had a single point of failure and
required constant network connection.
3. Distributed Version Control System (DVCS): Each developer has a
complete copy of the repository, allowing decentralized and offline work;
exemplified by Git.
4. Git's Emergence (2005): Created by Linus Torvalds, Git became popular
for its speed, efficiency, and distributed nature.
5. GitHub's Influence: GitHub, introduced in 2008, became a widely used
platform for hosting Git repositories, enhancing collaboration and code-
sharing.
4. Introduction
Git & GitHub
Git is used to tracking changes in
the source code, enabling multiple
developers to work together on non-
linear development.

5. Important Git Commands
git init: is used to create an empty Git repository.
git add:Makes sure that the changes are saved to the local repository
git status:Tells the current state of the repository.
git config:Configure the user.name and user.email.
git branch:Determine in what branch the local repository is on.
6. Continue
git checkout:Switch branches, whenever the work is to be started on a
different branch.
git merge:The command combines the changes from one branch to another
branch.
git remote :The git remote command is used to create, view, and delete
connections to other repositories.
git clone :The git clone command is used to create a local working copy of
an existing remote repository.
git pull :Fetch and merge changes from the remote repository to the local
repository.
