Here is a general outline of the key concepts and commands (arranged by topic) that you should know for the final.

The exam will have the following format:

1. Definitions: Briefly define terms using one or two sentences. (10 Points)

2. Short Answers: Briefly answer questions about:

   • Hardware (5 Points)

   • Data Structures / Algorithms (5 Points)

   • Code Evaluation (5 Points)

   • Networking (5 Points)

   • Web Programming (10 Points)

   • Data & Information (5 Points)

   • Privacy & Security (5 Points)

3. Programming: Write a Python involving requests and write a HTML document. (10 Points)

Parts 1 and 2 is to be done first on paper. However, part 3 can be done with the aid of your laptop and the Internet (but not other people).
