3. Analysis and Detail

   • Calculate the total number of characters: $2^7 = 128$
   • Therefore, ASCII can represent 128 different characters.

4. Verify and Summarize

   • Reviewing the options provided:
     • 512 different characters
     • 256 different characters
     • 128 different characters (correct answer)
     • 1024 different characters
   • The correct option that matches our calculation is 128.

Final Answer
