Question

How many bytes are there in 1011 1001 0110 1110 numbers?

• A. 1
• B. 2
• C. 4
• D. 8

Hint:

Always remember: 1 byte = 8 bits. To find bytes, divide total bits by 8. Binary numbers are often grouped into 4 bits (nibbles) for readability.

Answer 1

The Correct Option is B

A byte is defined as a group of 8 bits (binary digits).
The given binary number is: \[ 1011\ 1001\ 0110\ 1110 \] First, count the total number of bits:
Each group shown here has 4 bits (because of the spacing).
There are 4 groups: $4 \times 4 = 16$ bits in total.
Now, divide the total bits by 8 (since 1 byte = 8 bits):
\[ \frac16\ \textbits8\ \textbits per byte = 2\ \textbytes \] Therefore, the binary number given contains $\mathbf2\ bytes$.
This means the binary string can be stored in exactly two memory locations of size 1 byte each.
