Fill in the Blanks

What is the name of the component that loads in data while a program is running and while the CPU is doing calculations?

Open Ended

Explain one difference between RAM and the Hard-drive.

ROM is Read Only Memory

ROM permanently stores the instructions to 'boot up' (start) the computer

(RAM is Random Access Memory - used for running programs)

FDE cycle

In the central processing unit (CPU), the next code instruction is fetched from memory (RAM)

fetch

FDE cycle

In the central processing unit (CPU), the next code instruction is fetched from memory (RAM)

fetch

decode

The control unit (CU) decodes the instruction, so that it knows what task to process

FDE cycle

In the central processing unit (CPU), the next code instruction is fetched from memory (RAM)

fetch

decode

The control unit (CU) decodes the instruction, so that it knows what task to process

execute

The control unit (CU) signals to other parts of the CPU how to execute the task

FDE cycle

In the central processing unit (CPU), the next code instruction is fetched from memory (RAM)

fetch

decode

The control unit (CU) decodes the instruction, so that it knows what task to process

execute

The control unit (CU) signals to other parts of the CPU how to execute the task

Poll

Each step in the FDE cycle is necessary, of course. BUT if one of the steps were the most important -- which would you VOTE for?

• FETCH

• DECODE

• EXECUTE
