Git stands for Global information tracker and it is a version control system. Picture 1.0 shows the working principle of Git. Here data1 is a file that contains some code and data2 is the modified file of data1. By using version control that code was modified. In this example, we can also go to the older file(data1) and new file(data2) to do some version control operations i.e. edit information, retrieve information, delete files, and repository, etc. version control means we can edit, recover the deleted files or data, and access the older version code by entering some commands in the local system's(PC) terminal. Git stores the version control history. it helps us to secure the data, collaboration, and code management.
What is the difference Between Main Branch and Master Branch?
The main branch was created in the remote repository of GitHub(by default) whereas the master branch was created in the local repository.

Step4-:Push your local changes to GitHub:
git push origin master
Push your local commits to the repository on GitHub
