Mark Scheme

Question 1 (a)(i)

Solid state

Question 1 (a)(ii)

Fast access...
...less delays when turning the device on / turning pages etc

No moveable parts / robust
...can be handled / manipulated / moved without damaging it

Small / light enough...
...to fit within a hand held device

Low power
...to extend battery life of reader

Candidates need to identify a relevant characteristics of solid state storage for the first mark, and expand by explaining why this is an advantage in an e-book reader for the second mark.

Note: portable / capacity are not acceptable answers here (as solid state storage is not particularly more portable / larger than other forms of storage for this application)

Question 2 (a)

1 mark for identifying the reason why solid state was chosen, 1 mark for explanation.

e.g.

Is durable/robust // no moving parts
Less likely to be damaged // by example e.g. dropped

Faster read/write speed
Fats to boot // faster to load maps // more responsive

Small in size / light in weight
Reduces size of the sat nav // fit inside the sat nav

Lower power requirements
More suitable for running off batteries

Do not accept portability / reliability

Do not accept "faster" without clarification of what is faster.
