Answer:
Towers and satellite.
Explanation:
Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.
Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.
Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.
Basically, as a result of radio waves having long wavelengths, they are mainly used in long-distance communications such as the carriage and transmission of data.
The distance from one peak to the next peak is called wavelength. This distance is also equal to the distance from one trough of a wave to another.
Also, microwave is a form of radio waves which typically has short wavelengths and frequency ranging from 300 MHz and 300 GHz.
Hence, microwave transmits information between network nodes using towers and satellite.

The Correct Answer is B.) Ctrl+Alt+C
VPESR is an acronym (a word composed of the first letters of a phrase) that stands for Valence Shell Electron Pair Repulsion.
It's a scientific theory in the field of chemisty, and it predicts the shape of a molecule based on what atoms form this molecule.
If you want to understand the meaning of the name, you can devide it into
Valence shell electron
-electrons that are on the "outside" of the atom and can form bonds with other atoms
and it's the repulsion of these electrons that is being predicted.
