Multiple Select
Which of the following are functions of the CPU?
Perform calculations
Communicating with main memory

Storing all the commands of a loaded app while being used
3
The factors of CPU performance
Clock Speed - measured in Hertz - amount of instructions handled in one second (like all kinds of frequency)
Cache Memory - stores those commands frequently used - caching avoids data transfer between RAM and CPU
Word Length - how many bits can the CPU send/receive at once (32-bit, 64-bit, 128-bit
