In the middle of a high-pressure cybercrime investigation, you stumble upon a cryptic message. It appears to be encoded with the ASCII standard. The encrypted message contains a combination of lower ASCII and higher ASCII codes. Which statement is the most accurate concerning the interpretation of this message?
The lower ASCII codes, which range from 0 to 127, represent alphanumeric characters, punctuation, and control codes, which are essential for basic text processing. The higher ASCII codes, from 128 to 255, extend the standard to include characters used for graphic elements and symbols, which are often used in European languages and various document types.
Graphics files and documents use non-ASCII characters made in word processors, spreadsheet programs, or database programs and sent as email attachments.
