Explain why having cache memory can improve the performance of the central PROCESSING unit?
Because cache memory holds the frequently used instructions so it can be accessed quicker than it would be from RAM.
state two characteristics, other than the size of cach
e memory that improve the performance of the cpu's.Increasing the clock speed so it can do more calculations per second.
Number of cores so it has more cores doing the task at hand.

state three other built in physical devices that allow data to be input to a typical tablet COMPUTER.
Camera to input video
Microphone to input audio
GPS device so it knows where you are

State and explain two differences, other than cost and storage capacity, that make solid state media a better choice than magnetic media for tablet computers.
No moving parts. No moving parts so it is much quicker than magnetic storage.
Size. It is much smaller physically.
