To determine the correct ASCII code representation for the word "NOT," we first need to understand how ASCII (American Standard Code for Information Interchange) works. ASCII assigns a unique binary number to each character, which can be represented in decimal or binary format. Step-by-Step Explanation

1. Identify the ASCII Values:
2. Each character in the word "NOT" corresponds to a specific ASCII value:
   • 'N' has an ASCII value of 78.
   • 'O' has an ASCII value of 79.
   • 'T' has an ASCII value of 84.
3. Convert ASCII Values to Binary:
4. Next, we convert these decimal ASCII values into binary:
   • 'N' (78):
   • Decimal 78 in binary is calculated as follows:
     • 78 divided by 2 gives 39 remainder 0
     • 39 divided by 2 gives 19 remainder 1
     • 19 divided by 2 gives 9 remainder 1
     • 9 divided by 2 gives 4 remainder 1
     • 4 divided by 2 gives 2 remainder 0
     • 2 divided by 2 gives 1 remainder 0
     • 1 divided by 2 gives 0 remainder 1
   • Reading the remainders from bottom to top, we get: 1001110 (7 bits).
   • 'O' (79):
   • Decimal 79 in binary:
     • 79 divided by 2 gives 39 remainder 1
     • 39 divided by 2 gives 19 remainder 1
     • 19 divided by 2 gives 9 remainder 1
     • 9 divided by 2 gives 4 remainder 1
     • 4 divided by 2 gives 2 remainder 0
     • 2 divided by 2 gives 1 remainder 0
     • 1 divided by 2 gives 0 remainder 1
   • Reading the remainders from bottom to top, we get: 1001111 (7 bits).
   • 'T' (84):
   • Decimal 84 in binary:
     • 84 divided by 2 gives 42 remainder 0
     • 42 divided by 2 gives 21 remainder 0
     • 21 divided by 2 gives 10 remainder 1
     • 10 divided by 2 gives 5 remainder 0
     • 5 divided by 2 gives 2 remainder 1
     • 2 divided by 2 gives 1 remainder 0
     • 1 divided by 2 gives 0 remainder 1
   • Reading the remainders from bottom to top, we get: 1010100 (7 bits).
5. Combine the Binary Values:
6. Now, we combine the binary representations of 'N', 'O', and 'T':
   • 'N' = 1001110
   • 'O' = 1001111
   • 'T' = 1010100
7. Therefore, the complete binary representation for "NOT" is:
   • 1001110 1001111 1010100
8. Match with Given Options:
9. Now, we need to check which of the provided options matches this binary representation:
   • A. 101010010011111001110
   • B. 100111010011111010100
   • C. 100111110101001001110
   • D. 100111010101001111
10. None of the options directly match the combined binary representation of "NOT" (100111010011111010100). However, if we analyze option B, it appears to be a misrepresentation of the binary values, as it contains the correct binary for 'O' and 'T' but incorrectly represents 'N'.

Why Other Options Are Incorrect:

• Option A (101010010011111001110): This does not match any of the ASCII values for 'N', 'O', or 'T'.
• Option C (100111110101001001110): This also does not correspond to any of the ASCII values for the characters in "NOT".
• Option D (100111010101001111): This is a mix of binary values that do not correspond to the ASCII values of 'N', 'O', or 'T'.

Conclusion The correct binary representation for the word "NOT" is 1001110 1001111 1010100. However, the closest option provided is B, which contains parts of the correct binary but is not entirely accurate. Revision Summary

• ASCII assigns unique binary values to characters.
• The ASCII values for 'N', 'O', and 'T' are 78, 79, and 84, respectively.
• Their binary representations are 1001110, 1001111, and 1010100.
• The combined binary for "NOT" is 1001110 1001111 1010100, with option B being the closest but still incorrect.
