If you're talking about electronic communication, both analog and digital communication use a "carrier" frequency to send data. Voice can be across a wire without a carrier, but it's not very efficient. When a carrier frequency is used, the baseline frequency or amplitude can be modulated to transmit the data. In the case of a digital signal, the computer is watching the pulses. any anomaly in the pulses that are expected at a specific time can be converted to data. Data is validated using checksums and parity.

What is the advantages of multiplexing?
Because, the higher the data rate, the more cost effective the transmission facility. That is, for a given application and over a given distance, the cost per kbps decline with an increase in the data rate of the transmission facility.
What is the industrial frequency?
Industrial frequency, as used in Communications, aka the ISM band, is the frequency of signals between 900Mhz to around 2.4Ghz of encoded, compressed, or analog signals... industrial frequency can also refer to the common local power grid frequency (usually 60 or 50 Hz)
Rules that govern the orderly transfer of date within data communications?
FTP... I think...
What is the relationship between frequency and bandwidth in terms of data transmission?
Frequency and bandwidth are closely related in data transmission. Frequency refers to the number of cycles per second that a signal oscillates at, while bandwidth is the range of frequencies that a signal occupies. In data transmission, higher frequencies allow for more data to be transmitted in a given amount of time, resulting in a wider bandwidth. Therefore, a higher frequency signal typically has a larger bandwidth and can carry more information.
What is the purpose of protocols in data communications and how do they facilitate the exchange of information between devices?
Protocols in data communications serve as rules that govern how data is transmitted and received between devices. They facilitate the exchange of information by ensuring that devices can understand and interpret the data being sent, establish connections, and manage the flow of data. In essence, protocols enable devices to communicate effectively and reliably with each other in a standardized manner.
What is RAD Data Communications's population?
RAD Data Communications's population is 1,100.
When was RAD Data Communications created?
RAD Data Communications was created in 1981.
A physical path or a frequency used for signal transmission?
communications channel
Why isn't very high frequency VHF normally used for satellite communications?
The frequency is too low.
What is an 'ungrouped frequency table'?
A frequency distribution of numerical data where the raw data is not grouped.
What is the data item with the greatest frequency called?
The data item with the greatest frequency is the mode.
Can frequency distribution contain qualitative data?
frequency distribution contain qualitative data
Definition of broadband?
Broadband refers to telecommunication that provides multiple channels of data over a single communications medium, typically using some form of frequency or wave division multiplexing.
What does a basic communications system consists of?
A basic communications system consists of---------- 1.Two computers, one to send and one to receive data 2.communications devices that send and receive data 3. a communications channel over wich data is sent 4.All of the above
The transmission of data from one location to another is known as data?
communications
The number of times a data occurs?
the answer is frequency. the answer is frequency.
What is a diagram that shows the frequency of data?
A frequency diagram!
