  • C1024
  • D8000
Mark scheme
  • B 1000 (1)
  • The only correct answer is B. The correct answer is 1000.
  • A is not correct because 8 is the number of bits in one byte, not in one kilobit
  • C is not correct because 1024 is the number of bits in one kibibit, not in one kilobit
  • D is not correct because 8000 is the number of bits in one kilobyte (1000 bytes), not in one kilobit

No marks0/1

C 1024

Why: Near miss: 1024 is the number of bits in a kibibit, not a kilobit, so no mark.

No marks0/1
