Question 2 • 110 CCHS Introduction to Computer Science (Virtual)

Which of the following statements about version control are true? Select 3 options.

Answer

With distributed version control, multiple copies of the entire project are maintained on the developers’ computers.

Early version control systems needed to use locks to keep files synchronized, but newer version control systems do not use locks at all.

In a centralized version control system, the project files are stored in a repository or database on a server.

Git and Mercurial are examples of distributed version control systems.

Version control systems can only be used by teams of developers, rather than individuals.

Explanation

In distributed version control, each developer typically has a full copy of the project and its history, so A is true. A centralized system keeps the project repository on a server, making C true; Git and Mercurial are distributed systems, so D is true. B is false because some newer systems still support file locking, and version control is useful to individuals as well as teams, so E is false.
