GIT
What is Git?
Git is a distributed version control system (VCS) that helps track changes to files (usually source code). It enables multiple developers to work on the same project simultaneously without overwriting each other’s changes. Each user has their own local copy of the repository, which can be synchronized with a remote repository when necessary.
Key Features and Benefits
- Version Control: Git keeps the history of your project, allowing you to see who changed what, when, and why. This is invaluable for debugging and understanding the evolution of your code.
- Branching and Merging: Git allows you to create separate branches of your project, each representing a different line of development. This is essential for working on new features or bug fixes without affecting the main codebase. Once a branch is ready, it can be merged back into the main branch.
- Distributed Nature: Unlike centralized version control systems, Git doesn’t rely on a single central server. Each developer has a complete copy of the project’s history on their local machine. This makes it more easy to recover from failures and allows for offline work.
- Collaboration: Git is designed for collaboration. Multiple developers can work on the same project simultaneously, and Git helps to manage conflicts and keep everyone on the same page.
Version Control Systems (VCS)
A VCS (version control system) is a tool that helps manage changes to files over time and allowing you to roll back (undo) to previous versions if needed. It is essential for collaborative work, especially in software development, where many developers contribute to the same codebase.
Types of VCS:
- Local Version Control: Version control systems that track changes on a local machine, like simple file backups.
-
Centralized Version Control is like a central library for your code. Everyone who works on the project needs to go to this one library to check out the latest version or make changes. This can be a problem because if the library is busy or down, everyone else has to wait.
- Distributed Version Control (e.g., Git): Each user has a full copy of the repository on their local machine. This allows more flexible workflows and undo, as changes can be made offline and synced later.
