This article shows you what Git means. It is concise and easy to understand. It will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

What is version control?

Version control is a system that records changes in the contents of one or more files in order to consult specific version revisions in the future. For example, we version control the files that hold the software source code, but in fact, you can version any type of file. If you are a graphic or web designer and may need to save all revised versions of a picture or page layout file (which may be a feature you are eager to have), using a version control system (VCS) is a wise choice. With it, you can go back to the previous state of a file, or even the entire project to its previous state at a certain point in time, and you can compare the details of the changes in the file and find out who changed which place in the end. in order to find out the cause of the weird problem, who reported a functional defect and so on.

What is the version control system?

A version control system is a system or an application that automatically helps us to complete the above operations. (the system here does not refer to the operating system, but an application system. For example, when we do web projects, we often name the project: shopping mall system, ERP system, and so on, are they operating systems? No, it's just a program.

Third, how can the version control system help us control the version?

All the files we need for version control have to be submitted to a warehouse (actually a hidden folder), and all the changes we make to the files will be detected by this version control system. If we want to keep this version of the files, we should submit the files to the warehouse through the commands provided by the version control system, and then the version control system will automatically mark the version number for the documents we submit.

How many kinds of warehouses are there?

Local warehouse: set up a local folder.

Remote warehouse: a folder built on a server on the Internet.

5. How many version control systems are there?

1. Distributed version control system

Equipped with the above two warehouses, there is a local warehouse on your computer and a remote warehouse on a remote server. When we submit the document, we will first submit it to the local warehouse, and then, if there is a network, from the local warehouse to the remote warehouse on the network. Git is a typical distributed version control system.

2. Centralized version control system

Only equipped with the above remote warehouse, of course, if your computer acts as a remote server, then the remote warehouse is actually on your computer. When we submit the document, we submit it directly to the remote warehouse. SVN is a typical centralized version control system.

What is Git?

Git is a program that helps us manage file versions. The professional name is: distributed version Control system. And GitHub plays the role of the remote warehouse mentioned above, which is a folder stored on the extranet server. Of course, in addition to GitHub, remote warehouse also has Gitee (Code Cloud).
