A file has a size of 2 kibibytes.
State the number of bytes in the file.
Mark scheme
Award one mark for:
- 2048 (1)
- 2 × 1024 (1)
- 2^11 (1)
Allow 2048 bytes.
Do not accept 2000, which is the number of bytes in two decimal kilobytes.
Do not accept 1024, which is the number of bytes in one kibibyte.
Do not accept 16, which is the number of bits in two bytes.
Example answers and how they were marked
Full marks1/1
2048
Why: 2048 is 2 × 1024, the number of bytes in 2 kibibytes (1).
No marks0/1
2000
Why: 2000 uses the decimal kilobyte, not the binary kibibyte; the mark scheme does not accept it.
No marks0/1
16
Why: 16 is the number of bits in two bytes, confusing bits with bytes; the mark scheme does not accept it.
