Answer 1

Explanation:

Telecommunication is the transmission of information by various types of technologies over wire, radio, optical or other electromagnetic systems.[1][2] It has its origin in the desire of humans for communication over a distance greater than that feasible with the human voice, but with a similar scale of expediency; thus, slow systems (such as postal mail) are excluded from the field.
