This document is a brief introduction to the version control system. The main purpose of this topic is to elaborate on version controlling in software system development.
In General aspects, There are two kinds of version control one is centralized and another one is distributed.
Distributed version control is more modern, runs faster and has more features.
In centralized version control, each user gets a working copy, but there is just one central repository. One user can commit and update their changes at once. As soon as you commit, then only it will be available for others to update and to view your updates.
Every change made to the files by any of the users is tracked, along with who made the change, why they made it.
Benefits of Version Control System:
It is the solution to the long-term changes history of maintaining the file backup versioning. Every change made by the individuals if working in parallel in the team for the same project, you do not need to worry about the backup or merging their work.
Branching and merging make the benefit to a team member that provides the ability to work on an independent stream without having the affection of others, making changes in the same file. It provides the facility to merge that work back together, enabling developers to verify that the changes on each branch do not conflict.
Top Version Control Systems Git is free of cost and open source distributed version control (DVC) system for software programming advancement.
Git is a costless and open-source Distributed Version Control (DVC) system for software improvement. Git is a version control system that allows the user to manage their repositories in the product life cycle.
Git is particularly adept at organizing, branching, and dissemination of code. Git is a Version Control System (VCS) and that to be distributed system which was developed by Linus Torvalds

A version control system or VCS is a source of technics that tracks and manages changes to files by using a single repository within the team. A VCS also offers collective and collaborative utilities to share and integrate the file changes to other users.
Version control software monitors each alteration modification to the. If any pointless changes are made, a user can see back the history logs and analyze prior versions of the file with assistance to fix the mistake while limiting disturbance to all team members.
