Storage Device Applications
Watch and follow the YouTube video, the lesson contains three parts:
Key Information and content - all you need to do here is watch and listen. We recommend you take some notes for this one!
Learning activity - You are to complete the matching exercise and then justify the most appropriate storage device for each scenario.
Consolidation - these are past exam question and are for deliberate practice to check your understanding.
Task - Storage Device Scenarios Activity
Task - Exam Questions - Deliberate Practice
Question 1 (a)(i)
Question 1 (a)(ii)
...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
...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.
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.
