If you've ever saved a file as "report_final.docx," then "report_final_v2.docx," then "report_final_REALLY_final.docx" — you've already felt the problem version control solves, just without the tooling to do it properly.
Without a real system, tracking changes to code means either working alone or manually coordinating who's editing what. One accidental overwrite, and hours of work can vanish.
Git was originally created by Linus Torvalds, the creator of Linux, specifically to manage the Linux kernel's massive, fast-moving codebase.
Git records a complete history of every change as a series of "commits." At any point, you can see what changed, revert to a previous version, work on an isolated "branch," and merge changes together, with Git flagging real conflicts.
Git is the actual version control software, running locally. GitHub (and GitLab, Bitbucket) is a website that hosts Git repositories online, adding code review and issue tracking on top.
Every NOXEL360 product is built and tracked in Git — every fix, feature, and rollback fully recorded, with nothing lost even when things break.
The underlying idea — track every change, allow safe experimentation, always be able to go back — shows up everywhere: Google Docs' version history, WordPress revisions, design tools with undo history.
Git is the version control software running on your computer. GitHub hosts Git repositories online, adding collaboration features on top.
It's most common among developers, but the same idea shows up in simpler forms like Google Docs' version history.
Git detects the conflict and asks a person to manually decide how to combine the changes — it won't silently overwrite work.
A saved snapshot of changes at a specific point in time, with a message describing what changed and why.
An isolated copy of the codebase where you can make changes without affecting the main version until you're ready to merge.
Yes, Git itself is free and open source. Hosting platforms like GitHub offer free tiers with paid plans for advanced features.
Yes — this is one of Git's core strengths. You can revert to any previous commit if something goes wrong.
Not necessarily. Many tools offer graphical interfaces for Git, though the command line remains the most common way to use it.
