A

4

31
Q

True Or False: More cores means the system is usually faster?

A

False

32
Q

Finish the sentence
“It’s not about how many cores you are running,”

A

“t’s about which software you are running on them.”

33
Q

Programs have to be specifically developed to take advantage of multiple core processors. This is called?

A

Multi-Threaded Software

34
Q

Identify & explain the 3 components that make up the CPU?

A
