Final answer:
Donna engages in 'zipping,' which is the act of fast-forwarding through commercials on recorded programs. This is different from 'zapping,' which refers to changing channels to avoid commercials.
Step-by-step explanation:
When Donna records shows and fast-forwards through the commercials, she engages in a behavior known as zipping. This term describes the action of fast-forwarding through commercial breaks on a prerecorded program. The other options listed, such as pulsing, zooming, encoding, and zapping do not correctly describe this specific behavior. Zapping refers to changing the channel to avoid commercials, whereas zipping is specific to moving past them on recorded content.
- Zipping is specifically the action of fast-forwarding through commercials on recorded shows.
- Zapping would be changing channels to avoid commercials, which is not what Donna is doing.
- Donna's behavior indicates a common practice among viewers who prefer to watch content without interruption.
It's important to distinguish between these terms in the context of television viewer behavior, as they have implications for marketers and advertisers who seek to capture audience attention during breaks.
