Which item will stand FOURTH if the following are rearranged in ascending…

Concept

Data-storage units form a fixed size hierarchy: 8 Bits make 1 Byte, and from Byte upward each higher unit equals 1024 units of the one directly below it: Byte -> Kilobyte -> Megabyte -> Gigabyte -> Terabyte, with Bit remaining the smallest unit of all. To find which item occupies a stated position (for example, "fourth") once a set of units is rearranged in ascending order, list the given units from smallest to largest and read off the item sitting at that position.

Application

1. List the five given units: Terabyte, Bit, Megabyte, Gigabyte, Byte.

2. Arrange them from smallest to largest using the standard hierarchy: Bit < Byte < Megabyte < Gigabyte < Terabyte.

3. Count positions from the smallest unit: 1st = Bit, 2nd = Byte, 3rd = Megabyte, 4th = Gigabyte, 5th = Terabyte.

4. The item asked for is the one occupying the fourth position, which is Gigabyte (item 4 in the original numbering).

Cross-check

Cross-check using the hierarchy itself: 1024 Megabyte make one Gigabyte, and 1024 Gigabyte make one Terabyte, so Gigabyte sits directly between Megabyte and Terabyte -- exactly the fourth place when the five units are ordered from smallest to largest.

Result

Hence, the correct answer is Gigabyte (item 4).
