Computer Science Paper 1

What is the job of the ALU?

• To cease all CPU operations

• To hold the result from the accumulator

• To operate virtual memory

• To do the maths required by the insructiosn e.g  $\overrightarrow{xy}_{\left|\lceil332434x\rceil^{\left|\frac{\lceil54545x\rceil\int342345236547632_x^y}{352632764}\right|}\right|}\sqrt{43342}$

When Elizabeth opens alot of programs her computer seems to slow up. Why is this?

• Too much RAM

• too much CPU

• the hard drive is full

• Not enough RAM

Why would expanding her RAM capacity improve Elizabeth's computer speeds

• It would mean that virtual memory is less likely to be used as fast as it was

• It actually wouldn't it would slow it down more

• The CPU would now be at optimal efficiency

• She would no longer need a hard drive

Which of these are registers within the CPU?

• ALU

• PCU

• MDR

• AUL
