RRB Technician Grade 1 Model Paper 1

Concept:A nibble equals $4$ bits, and a byte equals $8$ bits, so one byte contains $2$ nibbles.Explanation:$1$ Kilobyte ($\mathrm{KB}$) is equal to $1024$ bytes.$1$ byte $= 8$ bits.$1$ nibble $= 4$ bits.Therefore, $1$ byte $= 8/4 = 2$ nibbles.So, $1$ Kilobyte $= 1024 \times 2 = 2048$ nibbles.This is because data is stored in bits, and nibbles represent half a byte.A byte can store one ASCII character, while a nibble holds only half of that data unit.Answer:$1$ Kilobyte is equivalent to $2048$ nibbles.Hence, the correct option is D. $2048$.
