Answer Key
Pebibyte (PiB)
Section A: Quick Questions
Q1
A — 1024 TiB
Q2
A — Pebibyte (PiB)
Q3
B — A PiB is larger than a TiB
Q4
B — 2 PiB = 2048 TiB
Q5
A — A very large data centre
Section B: Match the Pairs
Q1
1 PiB = 1024 TiB → One pebibyte is made up of 1024 tebibytes
Q2
PiB → The symbol for pebibyte, a unit used for huge amounts of data
Q3
A pebibyte is 1024 times bigger than a tebibyte, so TiB to PiB means dividing by 1024 → PiB = TiB / 1024
Q4
The pebibyte is the unit above the tebibyte on the storage ladder → GiB -> TiB -> PiB
Q5
1 PiB = 1000 TiB → Storage units use 1024 between steps, not 1000, so 1 PiB is 1024 TiB.
Q6
1 TiB = 1024 PiB → The units are the wrong way round. A PiB is the larger unit, so 1 PiB = 1024 TiB.
Section C: Definitions
Q1
PiB — A pebibyte (PiB) is a unit of data storage equal to 1024 tebibytes (TiB). It is used for very large amounts of data, such as in big data centres.Section D: Fill in the Blanks

GiB -> TiB -> PiB -> EiBSection E: Spot the Error
Q1
C — 1 PiB = 1024 TiB, so the divisor must be 1024, not 1000. It should be pib = tib / 1024.
Q2
D — The variable tib holds a number of tebibytes, so the label must be 'TiB'. It should be print(tib, 'TiB').
Q3
D — The closing bracket of print() is missing. It should be print(to_pib(4096)).
Q4
A — A pebibyte is 1024 tebibytes, not 1000. It should be tib_in_pib = 1024.
Q5
A — The larger unit that equals 1024 TiB is the pebibyte (PiB), not the exbibyte (EiB). It should be big = 'PiB'.
