What are the three levels in the memory hierarchy? How are they different?

What will be an ideal response?


The three levels are the sensory store, short-term memory and long-term memory. The sensory store is an extremely transient repository for data sent to it via the senses. Most of what comes into the sensory store is immediately discarded. The intermediate layer, short-term memory, has severe limitations in capacity and volatility. According to Miller’s article, short-term is capable of storing 7 ± 2 chunks. Long-term memory is virtually unlimited, but unfortunately it takes a great deal of effort and time to transfer data from short-term to long-term memory.
