Computer Fundamentals Or Terminologies

Step 1: Recall the hierarchy of digital storage units.
The units are based on powers of 2 (or 10 in some contexts), with each major unit being approximately 1000 (or 1024) times larger than the previous one.

Step 2: List the prefixes in increasing order.
Kilo (K) < Mega (M) < Giga (G) < Tera (T)

Step 3: Apply the order to the given units. - Smallest: 1 KB (Kilobyte) (D) - Next: 1 MB (Megabyte) (B) - Next: 1 GB (Gigabyte) (A) - Largest: 1 TB (Terabyte) (C)

Step 4: Form the correct sequence. The order from smallest to largest is D, B, A, C.
