Correct Answer
A. AM radio transmissionExplanation
In AM radio transmission, the amplitude of the carrier wave changes to carry the audio signal. This is achieved by varying the strength of the carrier wave in proportion to the amplitude of the audio signal. As a result, the peaks and troughs of the carrier wave are modulated to match the varying amplitude of the audio signal, allowing the signal to be transmitted over long distances and received by radio receivers.Rate this question:

Correct Answer
A. Video on demandExplanation
Video on demand systems use digital technology to make television interactive. With video on demand, viewers can choose and watch video content whenever they want, rather than being limited to scheduled programming. This technology allows users to pause, rewind, fast-forward, and even interact with the content through features like interactive menus and additional information. By providing a personalized and interactive viewing experience, video on demand systems enhance the traditional television experience and give viewers more control over their entertainment choices.Rate this question:

Correct Answer
A. FM broadcastingExplanation
FM broadcasting is a type of radio broadcasting where the frequency of the carrier wave changes. Unlike AM broadcasting, which varies the amplitude of the carrier wave, FM broadcasting modulates the frequency to transmit audio signals. This modulation technique allows for higher quality sound and less susceptibility to interference. FM broadcasting is commonly used for commercial radio stations and offers a wider range of frequencies, providing more channels for broadcasting.Rate this question:

Correct Answer
A. Digital music playersExplanation
Digital music players work differently than other music players because they have a solid-state memory that has no moveable parts. This means that instead of using a traditional spinning hard drive, digital music players use flash memory to store and play music. This makes them more durable and less prone to damage from physical shocks or drops. Additionally, solid-state memory allows for faster access to music files, resulting in quicker navigation and playback.Rate this question:
