In this final assignment, the topic of version control is addressed. Version control or source control is a method of developing computer programs and applications but is not necessarily used solely for that purpose. This method has enabled the development of many of today's systems and computer programs. In addition to version control itself, systems and tools that make this method easier to use are explained. The importance of these systems and their tools, as well as their classification, their applications, and their capabilities, are also explained in the assignment. Although there are several listed versioning tools and systems in the assignment, Git was chosen as an example of the system. Git was chosen as an example because it has one of the widest application capabilities and is one of the most robust version control tools available. Git as a system has by far the largest community, the largest number of active users and projects, and is the most common choice of version control tools over the last few years. Git is almost considered the standard of versioning control.
