Answer Key
Tebibyte (TiB)
Section A: Quick Questions
Q1
A — 1024 GiB
Q2
A — TiB is the abbreviation for tebibyte
Q3
B — Tebibyte (TiB)
Q4
A — 4
Q5
B — 1 TiB
Section B: Match the Pairs
Q1
1 TiB = 1024 GiB → One tebibyte is made up of 1024 gibibytes, the next unit up from the GiB
Q2
2 TiB hard drive → A typical hard drive size, enough to store a very large amount of data
Q3
The tebi prefix means 1024 to the power 4, so a tebibyte is 1024^4 bytes → 1 TiB = 1024^4 bytes
Q4
To change 3 TiB into gibibytes, multiply by 1024 because each TiB holds 1024 GiB → 3 * 1024 = 3072 GiB
Q5
1 TiB = 1000 GiB → Storage units go up in steps of 1024, not 1000, so 1 TiB is 1024 GiB
Q6
1 TiB = 1024 MiB → 1024 MiB is only 1 GiB. A TiB is 1024 GiB, the unit below it is the gibibyte, not the mebibyte
Section C: Definitions
Q1
TiB — Tebibyte: a unit of data storage equal to 1024 GiB. The tebi prefix means 1024 to the power 4. A typical hard drive might hold 1 or 2 TiB.Section D: Fill in the Blanks

Q1
C — The value was divided by 1024 to convert GiB into TiB, so the label must be TiB, not GiB.
Q2
B — 1 TiB is 1024 GiB, not 1000 GiB. Storage units use 1024, so the line should be gib ← tib * 1024.
Q3
A — There are 1024 GiB in 1 TiB. The constant should be 1024, otherwise every conversion that uses it is wrong.
Q4
B — Going from a smaller unit (GiB) to a larger unit (TiB) means dividing by 1024, not multiplying. It should be tib = gib / 1024.
Q5
C — A file fits when its size is less than or equal to the drive size in GiB (2 TiB = 2048 GiB). The comparison should be <=, not >=.
