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.

Answer:</h2>
Option A: Both POP3 and IMAP keep email on an email server by default.
is the correct answer.
<h2>
Explanation:</h2>
Following points will make the idea of POP3 and IMAP clear:
<h3>POP3:</h3>
- POP3 is the acronym for Post Office Protocol 3.
- POP3 is the method of receiving emails in which the emails received on the app can be downloaded on to the computer by having an internet connection.
- These downloaded emails can be viewed offline whenever needed and managed as well.
- POP3 makes it possible that the storage space of the default server do not run short as the downloaded emails are deleted from the server.
<h3>IMAP:</h3>
- IMAP stands for Internet Message Access Protocol.
- It is the method in which the mails are viewed and managed directly on the internet server instead of downloading them on the computer.
- IMAP makes sure to manage the mails so carefully and timely so that unimportant mails are deleted to make sure that the storage space does not run short.
<h3>
Conclusion:</h3>
So from these points we can make sure that both ways keep emails on email server but POP3 have option to download mails from server while IMAP dont have.
