Front

What is an advantage of digital storage over analog storage?

Back

A copy of an analog file is never as good as its original.

Front

What characteristic of a transverse wave can be doubled?

Back

Amplitude.

Front

What are digital signals composed of?

Back

Digital signals are composed of precise values that do not vary over time.

Front

What is an advantage of using radio waves in computer technology?

Back

Computers can be wireless.

Front

Define a wave.

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is the difference between analog and digital signals?

Back

Analog signals are continuous and can vary over time, while digital signals are discrete and consist of precise values.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum extent of a wave's oscillation, measured from its rest position.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is wavelength?

Back

Wavelength is the distance between successive crests (or troughs) of a wave.
