Lec-01 This is first lecture on Git in this series.in this lecture,i describe all the concept related to git,why we need git,what is distributed management system,what is source code management,how DCVS is different from CVCS.This tutorial will let you know all about Version Control System & Version Control Tools like Git.
Git & GitHub:
what is Git?

Git is a version control system that helps you keep track of changes made to your code over time.

It allows you to collaborate with others on a project, keep track of different versions of your code, and easily revert to previous versions if needed.

what is GitHub?

GitHub is a website that allows you to store your code online and collaborate with others. It uses Git as its version control system, so you can keep track of changes made to your code over time, work with others on the same codebase, and easily share your code with the world.

Why it is important?
Tracking the changes and updates. We can see who made which changes. Git also provides when and why a change was made.

Allowing them to work collaboratively. Software development projects usually require many people to work together. Git provides developers with a systematic way of doing that. Thus, the developers focus on the project instead of extensive communication sessions between the other developers.

Version Control:
Git - About Version Control

In the git version control system if you put anything it will have a version it will have the time it will have an author it will have a hash_id.

Hash - when you delete a file in git and one day you need that file that you have deleted so, in that case, u retrieved the file hash is a number and that number is stored in git that's why you retrieved the file.

Types Of Version Control Systems?
versions controls systems are two types:
Distributed version control system(DVCS)

Git is a Distributed Version Control System.

In DVCS every contributor has a local copy or clone of the main repository i.e everyone maintenance a local repo of their own which containers all the files & metadata present in the main repository.

Centralized version control system(CVCS)

GitHub is a Centralized Version Control System

suppose u have a repository and everybody came and distribute the code and suddenly the server is crash, in that case, everything in your code is gone.
