Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. 'A drive that uses the same kind of memory that flash drives use - but can reach data in only a tenth of the time a flash drive requires.'






2. 'A utility that regroups related pieces of files on the hard drive - enabling faster retrieval of the data.'






3. The maximum speed at which data can be transmitted between two nodes on a network; usually measured in megabits per second (Mbps).






4. A drive that plugs into a universal serial bus(USB) port on a computer and stores data digitally. Also called USB drive - jump drive - or thumb drive.






5. A program for editing digital video.
