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.
Table tool? i think because it gives more info
Answer:
USB cables.
Explanation:
Think of what would happen if you started walking to a friend's house that is 3 houses away from yours. You have a cell and there are no others that you can see. Your friend calls you.
Could you hear what he says with a blue tooth earphone? Likely.
If you are connected by a wifi device. Again likely.
What about a broad band. That would be possible too.
So what about a USB cable. Now there's a problem. The cable would have to be at least 75 feet long (city plots are usually somewhere in the neighborhood of 25 feet wide). You would need an awfully long cable. And that's only 3 houses away.
Answer:
the recycle bin?
Explanation:
usually when you overwrite something or delete it, it doesn't get entirely deleted rather stored in the recycle bin on your desktop i believe, and so you could retrieve applications through there
