What type of data representation does NOT fall under hard copy?

The correct answer is based on the distinction between hard copy and soft copy forms of data representation. Hard copy refers to any physical printed output of data that can be seen and touched, such as documents, photographs, and tape printouts.

In this context, diskettes do not fit the category of hard copy because they represent data in a digital format stored on magnetic media. Diskettes are physical items but do not display data visually in a printed form. Instead, they require a computer or a compatible device to read and interpret the data they contain.

On the other hand, the other choices, such as radiophoto prints, continuous printed tapes, and teletypewriter pages, all describe forms of hard copy output where data is physically printed and available to be read without needing any electronic device. Thus, diskettes are the only option that falls outside the definition of hard copy due to their nature as a storage medium rather than a printed representation of data.
