Match the component with its description:

Stavka koja se može prevući		Odgovarajuća stavka
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.
