Network speeds are measured in bits per second.
Identify the number of bits in one kilobit.
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
Example answers and how they were marked
Full marks1/1
B 1000
Why: Correct option: one kilobit is 1000 bits (1).
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
A 8
Why: Confuses bits with bytes: 8 bits make one byte, not one kilobit.
