Unit 1: Version Control Basics

Learn what version control is and why it's essential for development.

What is Version Control?

Understand the fundamental concept of version control systems.

Tracking History Collaboration Backup
Version control is a system that records changes to files over time so you can recall specific versions later. It allows multiple people to work on the same project without conflicts and provides a complete history of all changes.
Version 1 → Version 2 → Version 3 → Current
Each version is saved with timestamp and description
# Without version control:
project_final.doc
project_final_v2.doc
project_final_FINAL.doc
project_final_FINAL_FIXED.doc

# With version control:
project.doc (with complete history)

Benefits of Version Control

Discover why version control is crucial for any development project.

Key Benefits:
• Track every change with who, what, when, and why
• Easily revert to previous versions when bugs occur
• Enable multiple developers to work simultaneously
• Maintain backup copies automatically
• Branch for experimental features safely
• Merge changes from different contributors
Real-world Impact:
Version control eliminates the fear of breaking code, enables confident experimentation, and provides accountability for all changes. It's essential for any serious development work.

Centralized vs Distributed

Learn the difference between centralized and distributed version control systems.

Centralized VCS:
• Single central server stores all versions
• Developers check out files from central location
• Examples: SVN, CVS, Perforce
• Requires network connection for most operations
Distributed VCS:
• Every developer has complete project history
• Can work offline and sync later
• Examples: Git, Mercurial, Bazaar
• More flexible branching and merging

Unit 2: Git Installation and Setup

Install Git and configure your development environment.

Installing Git

Get Git installed on your operating system.

Windows macOS Linux
Git is available for all major operating systems. The installation process varies by platform, but the end result is the same - a powerful command-line tool for version control.
$
git --version
git version 2.40.1
Installation Options:
• Windows: Download from git-scm.com or use package managers
• macOS: Xcode Command Line Tools or Homebrew
• Linux: Use your distribution's package manager
• Always verify installation with git --version

Initial Configuration

Configure Git with your identity and preferences.

Essential Configuration:
Set your name and email address that will be associated with your commits. This information is included in every commit you make.
# Set your identity
git config --global user.name "Your Name"
git config
