DISTANCE Separation space between two reference points. The distance between your house (Reference 1) and the school (Reference 2)”

SHORT DISTANCE Considered as that where the reference points are at a distance that does not exceed the range of a room. It is measured with respect to the radius or diameter. In wireless communication, the minimum distance is usually one millimeter.”

LONG DISTANCE Two reference points are separated, occupying a long time to travel the space between one and the other.”

COMMUNICATION Consists of distributing or exchanging information. For this, it is necessary that there be at least one who gives the information (Issuer) and one who receives it (Receiver).”

SIGN It can be a gesture, such as a wink or signal with a part of the body, a specific action such as saluting the flag, an object, a quality such as color or size, an event such as an explosion or turning on a light.

SIGNAL In telecommunications, a signal is the information or message that is sent over a distance using a transmission medium.

TRANSMISSION MEDIUM It is the one through which the carrier energy of the signal travels. They are mainly copper cables, fiber optics, radio waves, the air, etc. When you perceive an image with your eyes, the transmission medium is air and the carrier energy is the light that reaches your eye.

CARRIER ENERGY It can be electrical, light (light) or radiation (such as radio waves, those transmitted in the air). The carrier energy will depend on the transmission medium.

CODE Combination of a set of specific signs and the rules for their use. For effective communication, whoever emits it and whoever receives it must know its use.

BINARY CODE It is made up of two values, that is why it is called binary. Those values ​​are 0 and 1. Where 1 represents the presence of the signal and 0 its absence. This signal is usually electrical voltage applied to the field of electronics.

SPEECH It is the expression through the voice using a specific language. It is also said that it is the oral representation of the Language.
