Match the component with its description:

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

What are CPU registers?

b. Short-term storage components 

c. Input devices 

a. Long-term storage components 

d. Output devices

In the context of the syllabus, what is the role of the Accumulator, and how many general-purpose registers are assumed to be present?

a. The Accumulator is used for gaming. 

b. The Accumulator is the main storage for all data. 

c. The Accumulator is used to store a single value, and there's typically only one general-purpose register. 

d. The Accumulator is used for handling network communications.

When using the Accumulator, what type of value is typically stored in it, and what purpose does it serve during instruction execution?

a. Text data is stored in the Accumulator, and it's used for printing.

b. It can store multiple values at once. 

c. The Accumulator stores a single value used by the ALU for instruction execution.
