2 E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is D. There are two types of storage loops in magnetic bubble memory: single-layer and double-layer.
In single-layer magnetic bubble memory, the bubbles are stored on a single layer of magnetic material. This type of memory is less expensive than double-layer memory, but it has a lower storage capacity.
In double-layer magnetic bubble memory, the bubbles are stored on two layers of magnetic material. This type of memory has a higher storage capacity than single-layer memory, but it is more expensive.
The following are the brief explanations of each option:
- Option A: There are 8 types of storage loops in magnetic bubble memory. This is incorrect. There are only two types of storage loops in magnetic bubble memory: single-layer and double-layer.
- Option B: There are 4 types of storage loops in magnetic bubble memory. This is incorrect. There are only two types of storage loops in magnetic bubble memory: single-layer and double-layer.
- Option C: There are 16 types of storage loops in magnetic bubble memory. This is incorrect. There are only two types of storage loops in magnetic bubble memory: single-layer and double-layer.
- Option E: None of the above. This is the correct answer. There are only two types of storage loops in magnetic bubble memory: single-layer and double-layer.
