A fan
29
True Or False: CPU are single, dual, or quad cores?
True
30
4 cores allows how many tasks at a time
4
31
True Or False: More cores means the system is usually faster?
False
32
Finish the sentence "It’s not about how many cores you are running,"
"t’s about which software you are running on them."
33
Programs have to be specifically developed to take advantage of multiple core processors. This is called?
Multi-Threaded Software
34
Identify & explain the 3 components that make up the CPU?
- Control Unit = directs or coordinates the operations of the processor - Arithmetic Logic Unit = performs the arithmetic and logic operation for the CPU - Register = random access memory used by the processor for fast access to instructions or calculations
35
What is RAM what does it do?
Is Random Access Memory it is very fast memory, used for quick access. Programs currently in use are stored on the RAM

True Or False: RAM is primary memory?
True
38
RAM has a low capacity usually how small?
4-16 GB
39
True Or False: RAM is permanent storage?
False
40
What is HDD & what does it do?
Hard Disk Drive it is very slower memory, because it is mechanical (moving parts)
41
True Or False: HDD is non-volatile?
True
