Question
Which mathematical base forms the underlying structural logic of standard computer memory capacity measurements?
A. Base 2 (Binary)
B. Base 8 (Octal)
C. Base 16 (Hexadecimal)
D. Base 10 (Decimal)
Answer: Option A
Solution (By JKSSB Mock Tests)
Computer systems process binary logic states (0 and 1). Thus, memory capacities naturally scale using powers of 2 (e.g., 2, 4, 8, 16, 32, 64).
