• Hard disk drive

The CPU is made up of several parts. What does ALU stand for?

• Addition Logic Unit
• Arithmetic Logic Unit
• Arithmetical Logical Unit
• Analogue Logic Unit

The CPU is made up of several parts. What does MAR stand for?

• Memory Address Register
• Machine Address Register
• Memory Application Register
• Memory Address Record

A CPU can contain more than one processing unit. What is each unit called?

• A CPU
• A core
• Cache
• A register

What is cache memory?

• Memory that is part of the main memory
• Another word for ROM memory
• Another word for RAM memory
• A very small and fast memory located near the CPU.

• 
• 
• 

What are the tasks that the control unit carries out?

• The control unit controls the flow of data within the system
• Fetches data and instructions, decodes it and sends signals via buses to the hardware component
• To store the address location of the next instruction to be executed
• All of these
