Answer Key
Gibibyte (GiB)
Section A: Quick Questions
Q1
A — 1024 MiB
Q2
A — GiB
Q3
B — Gibibyte (GiB)
Q4
A — 1 GiB = 1024 MiB
Q5
B — A few GiB
Section B: Match the Pairs
Q1
1 GiB = 1024 MiB → One gibibyte is made up of 1024 mebibytes
Q2
GiB → The symbol for gibibyte, a unit of storage that a film or memory stick often measures in
Q3
To change gibibytes into mebibytes, multiply by 1024 → 3 GiB * 1024 = 3072 MiB
Q4
The gibi prefix means 1024 cubed bytes → 1 GiB = 1024 * 1024 * 1024 bytes
Q5
1 GiB = 1000 MiB → Storage units go up in steps of 1024, not 1000. A gibibyte is 1024 MiB.
Q6
8 GiB = 8 / 1024 MiB → Converting to a smaller unit means multiplying by 1024, not dividing.
Section C: Definitions
Q1
gibibyte — A gibibyte (GiB) is a unit of data storage equal to 1024 mebibytes (MiB). A film or memory stick is often a few GiB. The gibi prefix means 1024 cubed bytes.Section D: Fill in the Blanks

Q1
C — The value in gib is a number of gibibytes (3072 MiB DIV 1024 = 3), so the label must be " GiB", not " MiB".
Q2
A — A gibibyte is 1024 mebibytes, not 1000. Storage units in this system use 1024, so the line should be mibPerGib ← 1024.
Q3
B — Going from MiB to the larger unit GiB means dividing by 1024, not multiplying. It should be gib ← mib DIV 1024.
Q4
C — Going from MiB to the smaller unit KiB means multiplying by 1024, not dividing. It should be kib ← mib * 1024.
Q5
D — The number of films that fit is stored in count (16 GiB DIV 4 GiB = 4). The program should output count, not stick.
