Reorder the following into size from smallest to largest (Left to Right)

• byte

• bit

• mebibyte

• kibibyte

• nibble

Reorder the following so the FDE cycle makes sense (Left to Right)...

• Decode the instruction and prepare to execute it

• Return instruction and or data down the data bus

• Fetch instruction from RAM

• Control Unit works out what to do next

• Execute either load, store, arithmetic or logic on the instruction

• PC is incremented

• address is copied to the Memory Address Register

• fetching data from memory, performing calculations in the ALU, or storing the result in the Acc

• MAR sends a signal to the main memory

• Control Unit decodes the instruction from its binary form

• instruction is then copied to the Memory Data Register

• Control Unit determines what actions are required for the instruction

• cycle then restarts from the 'Fetch' stage to process the next instruction

• Control Unit sends control signals to the appropriate parts of the computer to carry out the ins
