Answer Key
Mebibyte (MiB)
Section A: Quick Questions
Q1
A — 1024 KiB
Q2
A — Mebibyte (MiB)
Q3
B — 3 × 1024 = 3072 KiB
Q4
A — A few MiB
Q5
B — 1 MiB is bigger than 1 KiB
Section B: Match the Pairs
Q1
1 MiB = 1024 KiB → One mebibyte is made of 1024 kibibytes, so going up from KiB to MiB means dividing by 1024.
Q2
MiB → The symbol for mebibyte, a unit often used for the size of a photo or a song.
Q3
The mebi prefix means 1024 squared, so 1 MiB is 1024 x 1024 bytes. → 1 MiB = 1024 * 1024 bytes
Q4
To change a size in KiB into MiB, divide by 1024. → MiB = KiB / 1024
Q5
1 MiB = 1000 KiB → Storage units go up in steps of 1024, not 1000, so 1 MiB is 1024 KiB.
Q6
2048 KiB = 2048 * 1024 MiB → Converting from KiB to the larger unit MiB needs a division by 1024, not a multiplication. The correct answer is 2 MiB.
Section C: Definitions
Q1
mebibyte (MiB) — A unit of data storage equal to 1024 kibibytes (KiB). The mebi prefix means 1024 squared. A typical photo or song is a few MiB in size.Section D: Fill in the Blanks
Q1
1 MiB = 1024 KiBQ2
1 MiB = 1024 KiBQ3
1 MiB = 1024 KiBQ4
3 MiB = 3 x 1024 = 3072 KiBQ5
2048 KiB / 1024 = 2 MiBSection E: Spot the Error
Q1
B — Going from KiB to MiB means going to a larger unit, so you divide by 1024. It should be mib ← kib / 1024. Multiplying makes the number bigger instead of smaller.
Q2
D — The variable kib holds a value in kibibytes, so the label must be KiB, not MiB. It should be OUTPUT kib & " KiB".
Q3
B — 1 MiB is 1024 KiB, not 1000 KiB. Storage units use 1024, so it should be photoMiB * 1024.
Q4
D — The variable bytes holds a number of bytes, so the label must say bytes, not KiB. It should be OUTPUT bytes & " bytes".
Q5
C — photo_mib was found by dividing KiB by 1024, so it is measured in MiB. The label should be 'MiB', not 'KiB'.
