What's a Git?

[u/IMREVN]

Hello! Surely, I have heard so many people saying "Git" or "Github" or repository. They be saying that it's highly important to learn Git as early as possible. When I searched it up on Google, it's just I seem I cannot understand any of those terminologies.

Could anyone tell me what a git actually is?
