Question 1

Access time

Answer 1

The time it takes a storage device to locate it’s stored data.

Question 2

Cache Memory

Answer 2

Small blocks of memory, located directly on and next to the central processing unit (cpu) chip that act as holding places for recently or frequently used instructions or data that CPU accesses the most. When these instructions or data are stored in cache memory, the CPU can more
quickly retrieve them than if it had to
access the instructions or data from
random access memory (RAM).

Question 3

Answer 7

A complete processing section from a central processing unit embedded into one physical chip

Question 8

CPU benchmarks

Answer 8

Measurements use to compare performance between processors

Question 9

CPU usage

Answer 9

The percentage of time to central processing unit CPU is working

Question 10

CPU usage graph

Answer 10

Records your central processing unit CPU usage for the past several seconds

Question 11
