Answer:
b: short term
Step-by-step explanation:
A hard drive or solid state drive stores long-term data. RAM (Random access memory) is like an extremely fast HDD/SSD that temporarily stores a small amount of data that the CPU needs immediate access to.
You can think of this sort of like baking. When you are baking, you have a limited amount of space on the counter where you can immediately use items you place on it. This space on your counter would be like your RAM. Then you have your fridge. Your fridge is where you can place lots of items for longer periods of time that you don't need immediate access to. The fridge would be like your HDD/SSD.
