How is data retrieved from the telephone?
how is data retrieved from the telephone? the transmitter converts the sound waves to electrical signals which are sent through the telephone network to the receiving phone. the receiving telephone converts the signals into audible sound in the receiver.
What is bus in 8085?
there are mainly 3 buses are there in 8085. They are: Address bus :-Used to carry address Data bus :- Used to carry data Control bus :-Used to carry signals such as control and timing signals
What are three ways microwaved are used?
They are used to transmit data, TV signals, and telephone signals. They are also used in ovens and radar.
Does a T line carry digital data over twisted pair wires?
Yes it does. It will carry digital data as well as voice signals.
Why a pair of modems is required to transmit the digital signals over a long telephone wire Why not a single modem?
first modem will be modulating electrical signals in the voice frequency range of a telephone channel. These signals can be transmitted over telephone line and demodulated by another modem at the receiver side to recover the digital data.
What are four kinds of cargo that the embedded wires of a bus of motherboard carry?
Electrical power control signals Data
What describes the combination of voice such as telephone video and data signals sent over the same network?
Convergence

According to Cisco, ISDN can carry voice, video, and data.--> the answer is Voice, Video, and Data -[*Big Elk]-voice,video and datavoice,video and datavoice,video and data
Why there is a current in telephone wire?
A current flows in telephone wires primarily to transmit voice and data signals. When a person speaks into a telephone, their voice is converted into electrical signals, which travel along the wire to the receiving end. This electrical current allows for the modulation of signals, enabling clear communication over long distances. Additionally, the current is necessary for powering components like the telephone's ringer and signaling functions.
What is signals in data communication?
In data communication, signals refer to the variations in physical quantities that carry information over a medium. These signals can be analog or digital, with analog signals representing data as continuous waves and digital signals encoding data in discrete binary values. The transmission of these signals enables the exchange of information between devices over various channels, such as wired or wireless networks. Effective signal transmission is crucial for ensuring data integrity and communication reliability.
What Technology used to modify analog signals to make them suitable for carrying data over a communication path?
MODEM (Modulator - Demodulator)modulates Digitals signals to Analog to send over Telephone lines and Demodulates Analog signals in Digital Signals.
What portion of the telephone network still depends on analog signals?
Analog data transmissions occurs every time you log onto the internet using your pc, your modem, and your telephone line.
