Final answer:
Data communication is the electronic transfer of data from one place to another, often in the form of binary data. This digital format supports clearer transmission and allows for data compression. The correct answer to the student's question is '2) Data communication'.
Step-by-step explanation:
The electronic transfer of data from one location to another is known as Data communication. This process commonly involves the conversion of information, such as cell phone conversations or television voice and video images, into digital data. The data is represented as a sequence of binary ones and zeros because this format allows for effective data transmission even with weak signals.
Furthermore, digital data can be compressed using computer algorithms, making it possible to transmit more information within each frequency range. This binary representation of data, where each one or zero is a bit, is fundamental in communicating data across various devices and platforms.
Therefore, out of the provided options, the answer is 2) Data communication.
