This article mainly introduces to you What is git and The role of git.
For a qualified programmer, the git tool is certainly no stranger. But for some novice programmers, it is a bit confusing. (Related recommendation: "How to use Git")
So what exactly is GIT?
GIT, the full name is Distributed version control system, git is usually used in programming, and git supports distributed deployment, which can effectively and quickly process everything from small to large to very large project version management. The biggest difference between distributed and centralized is that developers can submit locally, and each developer copies a complete Git repository on the local machine through cloning (git clone).
I think everyone is still confused after seeing this official explanation!
Below we can give an easy-to-understand example.
For example, when you write a programming document locally and find that some places need to be modified or deleted, some people may modify it directly in the current file, and some people will make a copy and modify it. , and then delete useless files. But when you find that the original file or another version is better, you may be at a loss.
Using the git tool at this time is a smart move. We can build a local version library, and whenever we need to modify it, we can submit the previous version and indicate the characteristics of this version. In this way, there will be only one programming document in the folder. When you need a version, just restore it in the repository.
You may not know what a version library is here?
The version library, also known as repository , can be simply understood as a directory (a directory that stores many versions). All files in the directory are managed by Git, and modifications to each file , deletions, and Git will all be tracked so that the history can be tracked at any time or the modifications can be restored at some point in the future.
With this introduction, I believe everyone already has a certain understanding of git.
So what does git look like?
Below we can open a folder directory and click the right mouse button. Git GUI Here (a graphic user interface for Git) and Git Bash Here (Git command line interface) appear as shown in the figure below.
Here we have already installed Git. The Git command line interface is as follows, which is a tool for us to submit code to the warehouse.
This article is a brief introduction to Git. I believe everyone has a little understanding of it. I hope it will be helpful to those who are interested!

Git and GitHub are different tools: Git is a distributed version control system for managing code versions and collaborative development; GitHub is an online platform based on Git, providing code hosting and collaboration tools. Git's main features include version management, branch management, and collaborative development, while GitHub provides code hosting, collaboration tools and social networking capabilities.

GitHub is a Git-based version control system hosting platform that provides version control, collaborative development and community communication functions. Using GitHub can improve development efficiency and code quality.

Git and GitHub are different tools: Git is software for version control, and GitHub is an online platform based on Git. 1.Git allows you to track file changes and collaborative development. 2. GitHub provides code hosting and collaboration tools to enhance team development efficiency.

The core features of GitHub include version control, branch management, code review, issue tracking and project management. 1. Version control and branch management are based on Git, allowing tracking of code changes and experimental development. 2. Code review is implemented through PullRequest to improve code quality and team collaboration. 3. Issues tracking and project management are carried out through Issues and the project management board to improve project transparency and traceability.

GitHub is a powerful tool to improve the efficiency and quality of software development. 1) Version control: manage code changes through Git. 2) PullRequests: Conduct code review and improve code quality. 3) Issues: Track bugs and project progress. 4) GitHubActions: Automate the construction, testing and deployment process.

Git is a version control system, and GitHub is a Git-based code hosting platform. Git is used to manage code versions and supports local operations; GitHub provides online collaboration tools such as Issue tracking and PullRequest.

Git is an open source distributed version control system that helps developers track file changes, work together and manage code versions. Its core functions include: 1) record code modifications, 2) fallback to previous versions, 3) collaborative development, and 4) create and manage branches for parallel development.

Git and GitHub are not the same thing. Git is a version control system, and GitHub is a Git-based code hosting platform. Git is used to manage code versions, and GitHub provides an online collaboration environment.
