Question 13
13.

How is data transmission over the control bus synchronized?

Question 14
14.

In a computer system, where does the control bus transmit a signal from?

Arithmetic and Logic Unit (ALU)
Manages the flow of data within the processor and the entire computer system, ensuring correct handling of program instructions.
Controls the processor's internal activity cycles, allowing it to synchronize various processes.
Control Unit
Controls activities outside the processor and helps coordinate the operation of the entire computer system.
System Clock
The CPU operates at a specific clock frequency, defining the minimum time period between successive activities within the system.
