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:- Major property of a good hash code is that objects which are equal should return the same hash code .
Explanation: Hash codes is a numeric value which is used for identify a object while a equality testing .Hash code can occupy the value of any length and then returns a fixed length value. The value of hash codes are variable.
If two objects are equal then by the method of equal(object) if the hashcode() function is called on both the objects , they produce the same value.

Following actions could you most likely advise the client taking to strengthen the security of their wireless network-
- Change the default SSID to anything different.
- Turn off SSID broadcasting.
<h3>Explain the term wireless network security?</h3>
- Designing, putting into practice, and ensuring security on such a wireless computer network are all parts of wireless network security.
- A wireless computer network is further protected by this subset of network security.
- Wireless security is another name for wireless network security.
For the stated question-
- Disabling SSID broadcast and changing the network name are advised.
- By disabling SSID, the network name won't be displayed on devices looking for a network can connect to, and so by changing the name, it will be impossible for anyone who already knows the old name to connect.
- Both of which significantly boost security.
