Introduction to Version Control

This lesson introduces the concept of version control and explains why it is important for software development.

What is Version Control?

Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later. It allows you to track changes, collaborate with others, and maintain a history of your work.

Types of Version Control Systems

There are three main types of version control systems:

Local Version Control Systems
  • Local Version Control System: A local version control system stores changes to files in a database on the local machine. It allows you to track changes to files and revert to previous versions.
Centralized Version Control Systems
  • Centralized Version Control System: A centralized version control system stores changes to files in a central server. It allows multiple users to collaborate on a project and maintain a history of changes.
Distributed Version Control Systems
  • Distributed Version Control System: A distributed version control system stores changes to files in a distributed repository. It allows multiple users to work on a project independently and merge changes later.

Benefits of Version Control

Version control provides several benefits for developers and teams:

  • History Tracking: Version control systems maintain a history of changes to files, allowing you to track who made changes and when.

  • Collaboration: Version control systems enable multiple users to work on the same project and merge changes seamlessly.

  • Branching and Merging: Version control systems support branching and merging, allowing you to work on different features independently and merge changes later.

  • Backup and Recovery: Version control systems provide a backup of your work and allow you to recover previous versions of files.

Common Use Cases

Version control is commonly used for the following purposes:

  • Software Development: Version control is essential for software development to track changes, collaborate with others, and maintain a history of code changes.

  • Documentation: Version control is used to manage documentation, track changes to documents, and collaborate on writing projects.

  • Academic Research: Version control is used in academic research to track changes to research papers, collaborate with colleagues, and maintain a history of research projects.
