A Correct answer
Explanation

In telecommunications, a point-to-point connection refers to a communications connection between two nodes or endpoints. An example of this is a telephone call, in which one telephone is connected with one other, and what is said by one caller can only be heard by the other. Microwaves are widely used for point-to-point communications because their small wavelength allows conveniently-sized antennas to direct them in narrow beams, which can be pointed directly at the receiving antenna.
