In this session: Main parts of the CPU, control unit, arithmetic and logic unit, cache, levels of cache, Von Neumann Architecture, CPU registers & their purpose

Chapters:
0:00 Intro
0:16 What are the three main parts of the CPU?
0:25 Control unit
1:04 Arithmetic Logic Unit
2:09 Cache
3:07 Von Neumann Architecture
5:06 Von Neumann Architecture exam questions

__________________________________________________________

I'd recommend pausing the video on the questions at the end to test yourself on this topic - additionally, make yourself flash cards to test yourself, example:

On the front: what affects the CPU performance?
On the back: The CPU clock speed will determine how many FDE cycles can be performed in one second. The CPU can execute more instructions with additional cores as each core works independently.
