What Is Version Control? How does it work?

Today we will learn what is version control and how it works. Version control refers to a system that records changes to a single or set of files over a period of time to enable the user to remember specific versions later. As a web or graphic designer who wants to save every version of a layout or image, it’s best to use a version control system. It enables users to restore selected files to their previous state and compare changes over time.

You can also tell who made the last change which can interfere with your file or even restore an entire project to its original state. Version control includes version control tools, systems, or software. It is part of software configuration management, also known as VCS programming.

The whole premise of VCS is that it can be undone even if you lose important files or make a mistake. On top of that, you can enjoy all this with little overhead.

How does Version Control work?

It is important to understand how different version control systems work. The system allows multiple designers, developers, and other team members to work on a project together. This forces teams to work faster and smarter, and everyone can track changes as well

A greater need to manage components and versions of products, even as teams grow and develop becomes more complex.

Type of version control system

  1. Local Version Control System
  2. Distributed Version Control System
  3. Centralized Version Control System

1. Local Version Control System

It is a local database located on a local computer where every single file change is stored as a patch. Each set only contains adjustments to that particular file from the last version. If you actually want to see what this film looked like over a period of time, you need to add all the relevant patches to the file up to that period of time.

The primary problem with this system is that all data is stored locally. This is problematic because you lose all patches if something happens to this local database. Furthermore, if a version of a file is affected, subsequent changes will be lost.

Collaboration using a local version control system is particularly difficult, almost impossible.

2. Distributed version control system

With this system, you can view the latest snapshot of your files from the server and fully mirror them with the entire repository history. Each collaborator within a project will own a local copy of the entire project (local database and full history). If a server dies or becomes unavailable, multiple clients can send a copy of that version of any project in the repository to other clients.

It can send this copy to the server when it becomes available again. This model is ideal because a client needs to have an exact copy. Best of all, it can be distributed more.

3. Centralized version control system

This type of VCS consists of a single server containing all available file versions. Therefore, clients can simultaneously pull files to the local computer, access the server, and push files from their local computer to the server. That way, everyone can tell what other collaborators are doing.

In a centralized version control system, administrators control what each collaborator can do, increasing collaboration efforts. The main problem with this VCS is that everything is stored in a centralized server. If something happens to this, no one will be able to collaborate, save their changes or pull files.

As with local VCS, your entire project history will be lost if your central database crashes and is not backed up. The only thing you’ll be able to restore is snapshots still on people’s local machines.

Popular VCS jargon


These are central defined locations, where all programmers or developers work and store code. This is the heart of any VCS. Repositories play the role of storing files as well as maintaining history. You can access the repository through network and version control software in version control systems. The former works as a server while the latter is a client. Once a successful connection is established, clients can save or restore any changes.


Branches of treasure are like trees. Branching helps create other developments. This is ideal when the development process takes two directions.


This is the directory where all development takes place. Developers check out every single one.

Commit to change

Committed code means saving all changes from a working copy to a central server. After committing changes successfully, they are available to team members. Other developers can later pull the changes, thus updating the working copy. Since commit is an atomic operation, it rolls back or succeeds. Developers can’t see a half-finished promise.

Working Copy

A working copy is a snapshot that the developer is actively working on. Any changes to the working copy are merged into the original repository. The former is considered a private work environment. Here, developers can systematically maintain their work in isolation from other developers.

Benefits of using version control

  1. Traceability
  2. Identity


Version control is a process that provides evidence of all changes and revisions made over a period of time. It allows users to view the file at different developmental stages and track the contributions of developers. You can track the changes from the original copy, the improved version, and finally the final version

When a developer works on the latest draft of a file, having an easily accessible history allows them to understand the purpose of the dataset.


Thanks to version control, current teams can analyze the creation, editing, and deletion of datasets from the first copy. This brings much-needed clarity to the software development process, ensuring that each version of a file is distinguishable from another. Hence, developers can easily identify the latest version of the document.


Version control represents a secure and practical method for managing software configurations. Companies and developers can work with high efficiency, which improves the quality of their products. At the same time, they can record and evaluate a comprehensive history of these improvements, eventually leading to a successful end product.
