Question

How does long distance data communication work?

Answer 1

In long distance data communication, a transmitter transmits the data which is passed through a data signal to a transmission medium which receives the signal and decodes the data to the receiver.

Explanation:

 It refers to the exchange of data between a source and a receiver via form of transmission media such as a wire cable. Data communication is said to be local if communicating devices are in the same building or a similarly restricted geographical area.

The device that transmits the data is known as source and the device that receives the transmitted data is known as receiver. Data communication aims at the transfer of data and maintenance of the data during the process.

Answer 2

Throughout long-distance data communication, a transceiver sends the information to a data transmission which amplifies the information and decodes the message to the gateway via a data signal.

Explanation:

• Digital data may be transmitted over such small distances as direct, two-level electrical signals via simple copper conductors.

• This tends to result in electrical distortion of coverage criterion through long coils and added noise to the sensor as it spreads through a medium of transfer.

• Full distance communication equipment is very important. Communication occurs either by means of heliograph signals using a flashing mirror, electrical lamps, spotlights, colored disks, etc. or by means of radio or wires in confined space station areas.
