EDEXCEL GCSE (1CP2) Common CPU components and their function

What is the primary function of the Arithmetic Logic Unit (ALU) within the CPU?

• Sending signals to control data movement

• Providing fast access to frequently used instructions

• Performing arithmetic calculations and logical decisions

• Holding the address of the next instruction to be executed

Which CPU component is responsible for sending signals to control how data moves around the CPU and coordinating its operations?

• Arithmetic Logic Unit (ALU)

• Cache

• Control Unit (CU)

• Registers

What is the main purpose of the cache in a CPU?

• To store the address of the next instruction

• To perform arithmetic and logical operations

• To provide fast access to frequently used instructions and data

• To synchronize related components by generating pulses

Which type of bus is unidirectional and carries the addresses where data needs to be written to or read from?

• Data bus

• Control bus

• Address bus

• Register bus
