Explain the concept of memory depth in the context of memory organization.
Memory depth refers to the number of addressable locations in memory.
What are the typical word lengths used to express memory capacity?
Common word lengths used to express memory capacity are 8, 16, and 32 bits.
Describe the physical characteristics used to classify memory.
Physical characteristics of memory include volatile/non-volatile and erasable/non-erasable properties.
How can memory be organized as an array of locations? Explain.
Memory can be organized as an array of locations, with each location holding n bits and having an address.
What is the main characteristic used to describe memory capacity, and how is it typically expressed?
The main characteristic used to describe memory capacity is its capacity in terms of bytes or words, typically expressed using word lengths such as 8, 16, and 32 bits.
