Git Basics to Advance
Git is an open source version control software created by Linus Torvalds, creator of Linux kernel that allows users to track changes and manage different versions of projects as they change over time. Git users can create a solo project or with teams and quickly identify changes made, especially if issues arise within the code. The git repository behaves a little differently than other version control software. It stores your changes in a series of snapshots instead of creating sets of files (a system sometimes known as delta-based version control). Git needs only local files, so the speed of use is a considerable improvement over other systems that have network latency. Using Git gives you access to every version, but it doesn't feel like every version loaded into your system.
Git allows each git user to host a full repository directly on the individual computer. Git commands give each user full access to their local repository even when offline, synching with the larger remote repository the next time connectivity is available. The repository contains a series of git commit objects and references to those objects (heads). Commits refer to each change in the project with references to the parent commit objects, plus something called SHA1 ( a unique code that identifies each commit). The git log shows file changes and new branches keep everything organized. Learning Git allows you to manage large scale projects and track changes from a vastly efficient network that's housed on each computer. Users execute git pulls to integrate their newest changes with the remote repository. Versions are under control and teams can work on parallel projects through git branches.
