📋 Mark Scheme (b):
1 mark for choice either magnetic or solid state
1 mark per bullet to max 3 for justification e.g.
Magnetic:
• Large storage capacity
• … for storing software/videos/HD
• Television unlikely to be moved
• … therefore durability/portability not required
• Cost to purchase is low
• … so the TV will be cheaper to
manufacture/purchase
• Device will fit in a tv // device is small
• Longevity // reliable
Solid state:
• Large storage capacity
• … for storing software/videos/HD
• Television may be moved
• …therefore durable/robust/portable
• Fast data access
• … television will be more responsive
• Cost to purchase is low
• …so the TV is not too expensive to
manufacture/purchase
• Run quieter
• Produce less heat
• Use less energy
• Compact // lightweight
• …so tv can be made smaller / lighter

📋 Mark Scheme (a):
Primary
• to store (active) data/instructions/software/OS that the processor needs to access
// without primary the computer won't be able to start up/work
// (ROM) so the start-up instructions are not deleted when the computer turns off
// (RAM) to store the currently running data/software/instructions
// (Cache) to store frequently used data/instructions
Secondary
• to store data/files long-term/permanently
// without secondary the user's files will not be stored when the power is turned off
// store data not currently being used
/ 2
b) Give one example of a secondary storage device that the artist’s computer will have and an example of the data that will be stored on it
