Answer Key
Kibibyte (KiB)
Section A: Quick Questions
Q1
A — 1024 bytes
Q2
A — Kibibyte (KiB)
Q3
B — 1024
Q4
B — 1 KiB = 1024 bytes
Q5
A — KiB
Section B: Match the Pairs
Q1
1 KiB = 1024 bytes → One kibibyte is made up of 1024 bytes
Q2
KiB → The symbol for kibibyte, the first unit above the byte
Q3
The kibi prefix means 1024, so a kibibyte is 1024 bytes → 1 KiB = 1024 B
Q4
To change kibibytes into bytes, multiply by 1024 → bytes = KiB x 1024
Q5
1 KiB = 1000 bytes → A kibibyte is 1024 bytes, not 1000 bytes. The value 1000 belongs to the decimal kilobyte, not the kibibyte.
Q6
byte -> MiB -> KiB → The order is wrong: KiB is the first unit above the byte, so it must come before MiB.
Section C: Definitions
Q1
KiB — A kibibyte (KiB) is a unit of data storage equal to 1024 bytes. The kibi prefix means 1024, and KiB is the first unit above the byte.Section D: Fill in the Blanks
Q1
1 KiB = 1024 bytesQ2
1 KiB = 1024 bytesQ3
sizeBytes = sizeKib * 1024Q4
sizeKib = sizeBytes / 1024Q5

Q1
B — To convert KiB to bytes you multiply by 1024, not add. It should be size_bytes = 5 * KiB.
Q2
B — Going from bytes to the larger unit KiB means dividing by 1024, not multiplying. It should be size_bytes / 1024.
Q3
C — A kibibyte is 1024 bytes, not 1024 bits. The label should be 'bytes'.
Q4
C — 1024 bytes is one kibibyte (KiB), not a mebibyte. MiB is the next unit up, equal to 1024 KiB. It should print '1 KiB'.
Q5
A — One KiB is exactly 1024 bytes, but the digits have been mixed up. It should be bytes_in_kib = 1024.
