PCAD involves which types of information into the device?

• A. Drawing and tying
• B. Pictures and calendars
• C. Words and sounds
• D. Numbers and symbols

Answer: (A)

The key idea is how information is put into a PCAD—the input methods you use to feed data into the device. Drawing and typing are the primary ways a user can input messages: drawing lets someone create a visual representation or icon, while typing allows composing text directly. These two modes cover different abilities and together enable flexible communication with the device. The other options describe things the device might display or handle (pictures and calendars), or outputs that the device can produce (words and sounds), or alternative data formats (numbers and symbols). They aren’t about how you enter information into the device, making drawing and typing the best fit for input into PCAD.
