Answer 2

Answer: Computers communicate with one another and with the Internet via wires, cables, radio waves, and other networking equipment

Explanation:

A network is a collection of interconnected computers that can communicate data to one another. A computer network is similar to a social circle, which is a group of individuals who all know each other, share information on a regular basis, and plan activities together. Computers communicate with one another and with the Internet via wires, cables, radio waves, and other networking equipment. All data received via the Internet is converted into light or electrical pulses, often known as "bits," and then interpreted by the receiving computer. These bits are carried at the speed of light by wires, cables, and radio waves. The faster the Internet operates, the more bits that can move through these lines and cables at once.
