The communication media that can carry many voice, data, and video channels simultaneously over multiple frequencies is broadband.
Broadband is a type of communication that uses a wide range of frequencies to transmit data, voice, and video. It is a high-speed transmission technology that can carry a large amount of information simultaneously. The most common examples of broadband communication media are cable, DSL, and fiber-optic communication.
Broadband technology is capable of transmitting multiple channels of data over different frequencies. It uses a technique called frequency division multiplexing (FDM) to divide the available frequency range into multiple smaller frequency bands, each of which can be used to transmit data.
Each frequency band can carry multiple channels of information, such as voice, data, and video. For example, a cable modem can provide internet access, telephone service, and cable television all over the same physical connection.
Baseband communication, on the other hand, uses only a single frequency range to transmit data. It is commonly used in local area networks (LANs) and is limited in the amount of data it can transmit.
An analog modem is a device that converts digital data into analog signals for transmission over telephone lines. It is not capable of carrying multiple channels simultaneously.
CSMA (Carrier Sense Multiple Access) is a networking protocol used to manage access to a shared communication medium. It is not a communication medium itself and does not carry voice, data, or video channels.
