Answer:
Cell.
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.
In the field of telecommunication, all telecommunication setup are designed and developed to make use of two network devices: one device is typically used for the transmission of data while the other device is used to receive data that are sent on the network.
Generally, cell towers are tall poles that are used to transmit frequencies to mobile phones.

400*2*1.5
1.5 is another way to say 1 1/2
Answer:
Process - centered technique
Explanation:
Process - centered technique -
It is the method , where the useless or waste data is converted to some useful information , is referred to as process - centered technique .
This conversion process requires some activities , like maintenance/support , implementation , design , analysis and planning .
Hence , from the given information of the question,
The correct option is Process - centered technique .
