Learning Source Control systems – GIT

Source control systems, also known as version control systems, are a type of software tool used in program development to manage changes to the source code and other software artefacts.

Source control system track and manage change to files and directories, recording who made the changes, when they were made, and what was changed. They allow developers to

• Collaborate on code changes
• Work on multiple versions of the code simultaneously – using branches
• Merge changes from multiple developers into a single code base.
• Roll back changes
• Recover lost code
• Maintain a complete history of all changes to the code base.

Some popular source control systems include Git, Subversion, Mercurial, and Perforce. The source code system is regarded as a best practice in software development, as it helps teams collaborate more effectively, maintain code quality, and reduce the risk of errors and bugs in the code base.

In this blog, we share some basics of Git. Git is the most commonly used source control system. If you are an aspiring developer, it is important that you have a good understanding of GIT.
