somewhat slower than magnetic core memory
a volatile memory
somewhat larger than the magnetic core memory
All of the above E. None of the above
Answer is Wrong!
Answer is Right!
The correct answer is: B. a volatile memory.
Semiconductor memory is a type of computer memory that uses semiconductor technology to store and retrieve data. It is a volatile memory, which means that it loses its contents when

the power is turned off. Semiconductor memory is much faster and smaller than magnetic core memory, which was the main type of memory used in computers before semiconductor memory was developed.
Magnetic core memory is a type of computer memory that uses magnetic cores to store data. It is a non-volatile memory, which means that it does not lose its contents when the power is turned off. Magnetic core memory was the main type of memory used in computers before semiconductor memory was developed. However, it is much slower and larger than semiconductor memory, and it is no longer used in modern computers.
Here is a brief explanation of each option:
- Option A: Semiconductor memory is somewhat slower than magnetic core memory. This is not true. Semiconductor memory is much faster than magnetic core memory.
- Option B: Semiconductor memory is a volatile memory. This is true. Semiconductor memory loses its contents when the power is turned off.
- Option C: Semiconductor memory is somewhat larger than the magnetic core memory. This is not true. Semiconductor memory is much smaller than magnetic core memory.
- Option D: All of the above. This is not true. Only option B is true.
- Option E: None of the above. This is the correct answer.
