2.arithmetic logic unit
3.cache - 2what is the purpose of the control unit?has overall controll of the CPU , controls flow of data to registers and ALU.
- 3what is the purpose of the ALUdoes all the calculations, binary shifts logic operations and
- 4what is the purpose of the cachevery fast memory, stores frequently used memory so it is availible quickly.(low storage, faster than RAM)

then copies the instruction from MAR to MDR - 6what is decode in fetch decode execute cycle?instruction from the MDR is decoded by the control unit then prepares for next step.
