The size of a computerʹs memory is measured by the number of bytes that it can store. The following table lists the
number of bytes in commonly used storage units. $$\begin{array} { l | l }
1 \text { kilobyte } ( \mathrm { KB } ) & 2 ^ { 10 } \text { bytes } \
\hline \text { 1 megabyte (MB) } & 2 ^ { 20 } \text { bytes } \
\hline 1 \text { gigabyte (GB) } & 2 ^ { 30 } \text { bytes } \
\hline 1 \text { terabyte (TB) } & 2 ^ { 40 } \text { bytes }
\end{array}$$ Calculate the number of bytes in the following.
-1 kilobyte
A) 1,048,576
B) 1,000,000
C) 1000
D) 1024
