Difference Between Git and GitHub:
Git:
1. Version control system: Git is a distributed version control system that runs on your local machine.
2. Manages code changes: Git tracks changes, manages branches, and enables rollbacks.
3. Local repository: Git stores your code repository locally on your machine.
GitHub:
1. Web-based platform: GitHub is a web-based platform that hosts Git repositories.
2. Collaboration and sharing: GitHub enables collaboration, sharing, and management of code with others.
3. Remote repository: GitHub stores your code repository remotely, accessible via the web.
Git is the tool that manages your code changes locally, while GitHub is the platform that hosts your code repository online, facilitating collaboration and sharing.
Git is like a local file cabinet that stores and manages your documents.
GitHub is like a cloud-based file storage service that allows you to share and collaborate on those documents with others.
