.
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. Striped set with dedicated parity at the byte level - data at the byte level is striped across multiple disks - but an additional disk is leveraged for storage of parity information - which is used for recovery in the event of a failure. allows for d
