If an unsigned integer contain 2 bytes then what will be the range of numbers?Options :-32768 to +327670 to 65535-128 to +128none of the above

Break Down the Problem

1. Identify the size of the unsigned integer.
2. Calculate the range of an unsigned integer using the formula.

Relevant Concepts

• An unsigned integer does not include negative values.
• The range of an unsigned integer can be calculated with the formula:
  $0 \text{ to } (2^n - 1)$ where $n$ is the number of bits.

Analysis and Detail

1. Determine the number of bits for the 2 bytes:

   • Since 1 byte = 8 bits, then 2 bytes = $2 \times 8 = 16$ bits.

2. Calculate the maximum value:

   • Using the formula for unsigned integers:
     $0 \text{ to } (2^{16} - 1)$
   • Calculating $2^{16}$:
     $2^{16} = 65536$
   • So the maximum value is:
     $65536 - 1 = 65535$

Verify and Summarize

• The range of an unsigned integer that contains 2 bytes is from 0 to 65535. This means the total range is:
  • Lower Bound: 0
  • Upper Bound: 65535

Final Answer

The correct option is: 0 to 65535.
