What are version control systems and why are they important?

Version control systems (VCS) are tools that help manage changes to source code over time. They allow multiple developers to work on a project simultaneously without conflicts, track changes, and revert to previous versions if needed.

Can you explain the difference between Git and SVN?

Git is a distributed version control system, meaning every developer has a full copy of the repository, while SVN (Subversion) is centralized, requiring a connection to a central server for most operations. This makes Git more flexible and faster for many workflows.

What are some common commands used in Git?

Some common Git commands include 'git init' to create a new repository, 'git clone' to copy an existing repository, 'git add' to stage changes, 'git commit' to save changes, and 'git push' to upload changes to a remote repository.

How do I resolve merge conflicts in Git?

To resolve merge conflicts in Git, you need to manually edit the files with conflicts, choose which changes to keep, and then stage the resolved files using 'git add'. Finally, commit the changes to complete the merge.
