======Questions======

1. **What is a version control system?**

A version control system(VCS) can be thought of as a "bookkeeping" system that keeps track of any changes to files over time. 

2. **Why is it useful?**

A VCS is useful to recall previous versions, compare different versions, and keep track of who contributed what. So if anything goes wrong, a VCS allows you too easily revert your files to an previous version.  

3. **What is git?**

Git is a command line tool that manages and stores different versions of files. It also allows you copy an entire project to your system so you can edit it locally before sending your modifications to a central server.

4. **What is Github?**

GitHub is a repository hosting service for Git that provides access control and allows for a higher level of collaboration.

5. **How are git and Github different from each other?**

Git is the VCS while Github hosts it and allows users to connect their work.

6. **Why do you think git or any other version control system can be useful?**

Git and other VCSs can be useful to keep track of changes and collaborate with other people to get a project done. It is also useful since it gets rid of having to manually keep and save all of your own versions. Lastly, if any errors have been made or you want to revise something entirely, Git and VCSs allow you to revert your files back to an older version.
