People communicate to exchange information.
A person sends information / a message. → The other person receives it and reacts / answers. The sender usually expects some feedback.

We usually use words to communicate ( = verbal communication: we speak or write), but we can communicate without words as well (= non-verbal communication): we use gestures, body language, signs and signals, symbols, icons etc. We often combine several kinds of communication: we use gestures when speaking, symbols when writing etc. We use non-verbal communication to express our feelings, emotions, opinions (happiness, anger, love…).
We can communicate face-to-face or over a long distance.
We use speaking and gestures when communicating face to face.
We use modern technologies for communication over long distances.

In the history, people wrote letters to communicate with other people over long distances. Since the 19th century modern technologies have been used: the telegraph and the radio,  the telephone, fax machines, and the computer.
Years ago,  it took time to deliver a message. Today, you can often get an instant reply.
Written messages and our voice are transported in the form of  electric signals via wires and optic cables or sent through the air to satellites and back to Earth using modern wireless technologies.
