KS3 Von Neumann Architecture

Match the definition to the component.

The brain of the computer, it processes instructions before directing the computer to execute any tasks it has been given.

• Central Processing Unit

• Random Access Memory (RAM)

• Control Unit

• Read Only Memory (ROM)

Match the definition to the component.

Controls the CPU by sending signals around that tells each part what it needs to do.

• Read Only Memory (ROM)

Match the definition to the component.

Small pieces of memory that store key pieces of information during the FDE Cycle.

• Registers

• Secondary Storage

• Read Only Memory (ROM)

Match the definition to the component.

Handles any mathematical tasks that the CPU is asked to complete.

• Registers

• Arithmetic Logic Unit (ALU)

• Read Only Memory (ROM)

Match the definition to the component.

Used to store files for long amounts of time, until they are needed in RAM when they are opened.

• Registers

• Secondary Storage
