Question

q3) how many bits are there in a terabyte? * 1 point
2^30
2^40
2^43

Explanation:

Step1: Recall storage - unit conversion

1 byte = 8 bits. 1 Terabyte (TB) = $2^{40}$ bytes.

Step2: Calculate bits in a Terabyte

Number of bits in 1 TB = $8\times2^{40}=2^{3}\times2^{40}$.
Using the rule of exponents $a^{m}\times a^{n}=a^{m + n}$, we have $2^{3}\times2^{40}=2^{43}$.

Answer:

$2^{43}$
