What are the three network media and the signals they transmit?
The three main types of network media are twisted pair cables, coaxial cables, and fiber optic cables. Twisted pair cables, commonly used in Ethernet networks, transmit electrical signals. Coaxial cables also carry electrical signals and are often used in cable television and internet connections. Fiber optic cables transmit data as light signals, allowing for high-speed and long-distance communication.
What types of signals are used to transmit data on a wireless network?

What devices can have a wireless amplifier?
There are many different devices that have the capability of using wireless amplifiers. Any device, or network of devices, that produces radio signals, such as a WIFI network or a VHF radio system, can use wireless amplifiers or repeaters. These repeaters transmit signals further then the source transmitter can transmit. There are also numerous wireless amplifiers on the market to use with guitars.
What are characteristics of broadband?
each channel can only transmit signals in one direction signals are transmitted as rf waves can be used to transmit multiple signals at once
How would you describe broadband?
each channel can only transmit signals in one direction signals are transmitted as rf waves can be used to transmit multiple signals at once
Why must a modem to be used to transmit binary data through a PSTN?
A modem is necessary for transmitting binary data over a Public Switched Telephone Network (PSTN) because it converts digital signals from a computer into analog signals that can travel over the telephone lines. The PSTN is designed for voice communication, which uses analog signals, so the modem acts as a translator between the digital data and the analog format required by the network. Additionally, the modem ensures that the data can be reliably sent and received, handling modulation and demodulation processes effectively.
Why are the 802.11b and 802.11g wirless transmission technologies more commonly used on business LANs than Bluetooth?
802.11 signals travel farther than Bluetooth signals, and 802.11 technologies transmit data at higher throughputs than Bluetooth.
Do cellphones use microwaves?
Yes, cellphones use microwaves to transmit and receive signals to and from cell towers. Microwaves are a type of electromagnetic radiation that allows for wireless communication between cellphones and the network infrastructure.
What is neurons transmit signals across a?
the nucleus.
How the nerves transmit signals to the brain?
Nerves use electrical impulses to transmit signals to the brain. The gaps between the nerve endings are called synapses.
