Version Control System:

So what does version control system mean? It is a software which is used by many software developers and this software help developer to track the changes developers make in code over time. It is used to take a backup or snapshot of your code that you can recall later if you need it.

VCS provides a way to the developer to work with different version of the code so that we can save different features and make notes as we progress and have a different version that we can retrieve and through time. Version control system also helps the developer to collaborate with other developers and incorporate with the different version of any project or piece of code that different developers wrote.

What is Github?

There is a misconception that Git and Github is the same thing but they are not. Git is the technology while the Github is a website or an application that works with Git.

Why should we care about Git?

Git is used to tracking the changes in code, it is used widely by many developers and currently have more than 30 million repositories on GitHub. So if you will work in the team, so you need Git to track the changes that you make in code or your coworker make in code. It still one of the best tool to keep the changes even if you are working as an individual. It will help you to retrieve the previous code and keep the track of every single change that you make in your code and then these tracks will help you later in understanding the code and recovering the project.

Git is not just only for software development project or just only to keep the record of code it is also used to manage the process of writing novel, books or screenplay. So let’s suppose you are the writer and you have some Amazing story in your head, so you write that story and save it in your PC. After some time you want to change some part of your story then you will make a copy of your story. In copy version, you will make changes and then save it as a new file. Now if you want to make changes again then you will have to repeat the same process. So you have to keep track of every file and the changes you make. It is very hard for any individual to deal with many files. So that’s a problem, and to tackle this problem you will use Git. Just create a file and in that file, you will write the story and make changes. Git will track every change you make in your story and will help you to restore that changes later.
