Consider a logical address space of 8 pages of 1024 words mapped into memory of 32 frames. How many bits are there in the logical address?

  1. A.

    13 bits

  2. B.

    15 bits

  3. C.

    14 bits

  4. D.

    12 bits

Correct answer: A

To determine the number of bits in the logical address, we calculate the bits required for the page number and the offset. There are 8 pages, so log2(8) = 3 bits for the page number. Each page has 1024 words, so log2(1024) = 10 bits for the offset. The total logical address size is 3 + 10 = 13 bits.
