Heart of computer

Question

All of us must have read in our primary class that CPU is the brain of computer but did you ever wondered what could be the heart of computer?

This question was asked by me during my today's 12 computer practicle .

This made me wonder what other body parts could be compared to . Can you help me in this comparison .

In my opinion

Sole ~ OS
Heart ~ UPS
Blood ~ electricity
Ears ~ microphone
Mouth ~ speaker

Answer 1

(you mean "Soul"?)

Answer 2

Methinks blood would be the system interconnections/bus, and since heart controls blood flow, the control unit would be the heart.

... But CU is part of the CPU, which would be weird if your heart is placed inside your brain.

Answer 3

"Sole"

Answer 4

yes soul
