Answer Key
The unit ladder: byte to exbibyte
Section A: Quick Questions
Q1
A — bit, nibble, byte, KiB, MiB, GiB
Q2
A — GiB
Q3
B — GiB
Q4
A — Each unit is 1024 times the unit before it
Q5
B — EiB (exbibyte)
Section B: Match the Pairs
Q1
1 KiB = 1024 bytes → The kibibyte is the first unit above the byte on the ladder
Q2
1 EiB = 1024 PiB → The exbibyte is the top unit of the ladder, one step above the pebibyte
Q3
The full storage ladder in order from smallest to largest, starting at the bit → bit, nibble, byte, KiB, MiB, GiB, TiB, PiB, EiB
Q4
Above the byte, each unit is 1024 times the unit directly below it → 1 GiB = 1024 MiB
Q5
bit, byte, nibble, KiB, MiB, GiB → The nibble and byte are in the wrong order. A nibble (4 bits) is smaller than a byte (8 bits), so the nibble comes first.
Q6
KiB, MiB, TiB, GiB, PiB, EiB → TiB and GiB are swapped. The GiB comes before the TiB, because the TiB is 1024 times larger than the GiB.
Section C: Definitions
Q1
bit, nibble, byte, KiB, MiB, GiB, TiB, PiB, EiB — The storage unit ladder from smallest to largest. Above the byte, each unit is 1024 times the one before: 1 KiB = 1024 bytes, 1 MiB = 1024 KiB, and so on up to EiB.Section D: Fill in the Blanks

Q1
D — Each binary unit above the byte is 1024 times the one before, not 1000. It should be 1 MiB = 1024 KiB.
Q2
B — The ladder must run from smallest to largest. KiB is smaller than MiB, so the order should be 'byte', 'KiB', 'MiB'.
Q3
B — The unit directly below GiB is MiB, not KiB. KiB is two steps down the ladder.
Q4
C — The unit directly above TiB is PiB. EiB is two steps above TiB, because PiB sits between them.
Q5
C — A GiB is 1024 times the unit directly below it, which is the MiB. It should be 1 GiB = 1024 MiB.
