What is a VCS (Version Control System)?

Version Control is a software management system that allows the developers to work together and track all the changes related to the software project. It becomes more essential when the software project grows.

When you have multiple developers are working on the same project as well as on the same file. It will create problems when they merge the files back together. The reason behind this, it is unknown which version of the file is the correct one. So the concept of the Version Control System (VCS) is to reduce the complexity of developers and help to make the solutions relatively painless.

A VCS manages all the changes regarding projects like documents, computer programs, large websites, collection of information, and many more. The changes can be anything; it may be the addition of new files, modification of existing files, or deletion of a file. We can assume a version control system as a kind of database.

It helps the developers to take screenshots of the complete projects when needed. Along with this, Version Control allows you to safely work with the help of branching and merging. The developer copies the part of the source code to make safe changes without affecting the rest of the project. After the changes, if the code is working properly then merge the code back into the main source code to make it official.

Introduction to GitHub for beginners

Github is an online platform that offers a cloud-based Git repository hosting service. Essentially, it provides an easier way for both local and distributed teams to track the changes made by developers and collaborations. It is a user-friendly interface; so it can be used and take advantage of by anyone. If you are using Git, so you need to have more technical knowledge and use of the command lines.

Github is an American Company that was launched in April 2008 by Tom Preston-Werner, Chris Warnstrath, P.J. Hyett, and Scott Chacon. It hosts the source code in the various programming languages as well as tracks all the changes made by developers.

Github allows the developers to synchronize the source code or project store locally into the web. Additionally, it can be used to browse other people’s repositories and download the documents of the projects seamlessly. It provides backups of what you have done and allowing you to share with others. The developers can create a public and private repository.

By using GitHub, you can get the best features like bug tracking, feature requests, task management, and repository hosting for every software project.

Important components of GitHub are:-

  • Repositories
  • Branches
  • Commits
  • Pull Requests
  • Git

How GitHub Works?

GitHub offers many features such as forking, pull request, merging, and so on. Forking creates copy for your project where you can experiment freely without affecting the original project. After the changes, you have made in the code and you are happy with this. Then you can send the pull request to the project owner to review the changes. Moreover, you can also ask for any follow-up questions. If the project owners love your changes, they will merge your pull request. Then it will apply to the changes from your forked project to the original one.
