Understanding Computer Science Concepts

The video is a final review session for the APCS Principles exam, led by Sandy Chaka. It covers topics such as problems computers cannot solve, distributed computing, internet protocols, data structures, and procedures. The session provides resources, feedback opportunities, and exam strategies. It includes sample questions and an interactive Kahoot session to reinforce learning. The video emphasizes understanding vocabulary and using the exam reference sheet effectively.
