GIT Basics -1

  Git is a version control system used to track changes in software development projects. It is a powerful tool that allows developers to collaborate, share code, and manage changes to their codebase. Here are some basic concepts and commands to get started with Git: Git Repository : A Git repository is a collection of files and folders that are managed by Git. It can be stored locally on your computer or remotely on a Git server such as GitHub, GitLab, or Bitbucket. Git Commit : A Git commit is a snapshot of changes made to your codebase. It is a way to save your work and document what has been changed. When you make a commit, you are creating a new version of your code.

If you’re not sure if your touchpad supports gestures, open the Settings app and go to  Devices > Mouse & touchpad . Under the “Touchpad” heading it will say “Your PC has a precision touchpad” if you can swipe and tap in...
