Arrange the following digital storage units in ascending order of capacity:…

Concept

Storage-unit prefixes represent increasing orders of magnitude. Moving from kilo to giga to tera to peta increases capacity at every step; decimal and binary conventions differ in exact factors but preserve this order.

Application

1. Identify kilo as the smallest prefix among the four, so Kilobyte comes first.

2. The next larger prefixes are giga, tera, and peta, in that order.

3. Combining the steps gives Kilobyte → Gigabyte → Terabyte → Petabyte.

Cross-check

Using decimal definitions, the capacities are 103, 109, 1012, and 1015 bytes respectively. Their exponents increase as 3 < 9 < 12 < 15, confirming the same order.

Result

Kilobyte → Gigabyte → Terabyte → Petabyte
