Git
Git is the most commonly used version control system. Git tracks the changes you make to files, so you have a record of what has been done, and you can revert to specific versions should you ever need to. Git also makes collaboration easier, allowing changes by multiple people to all be merged into one source.
Fork
Fork is the Git GUI client, a tool that allows the developer to work with this version control system in a visual mode. It does not require writing commands manually, offering a convenient graphical interface with the in-built options. This way, one can perform the tasks faster and in a more comfortable manner.
Salesforce DX
The Salesforce CLI is a powerful command line interface that simplifies development and build automation when working with your Salesforce org.
Visual Studio Code
Visual Studio Code is a streamlined code editor with support for development operations like debugging, task running, and version control. It aims to provide just the tools a developer needs for a quick code-build-debug cycle and leaves more complex workflows to fuller featured IDEs, such as Visual Studio IDE.
Architecture
The architecture of a software system is a metaphor, analogous to the architecture of a building. It functions as a blueprint for the system and the developing project, which project management can later use to extrapolate the tasks necessary to be executed by the teams and people involved. [Source]
