BidirectionalThe adjective bidirectional allows you to qualify what you have two directions. This concept (address) refers to a trend, a direction, an orientation or a direction. For instance: “The municipal authorities decided that the Camino del Sur be bidirectional to speed up traffic”, “Discrimination is often two-way: people discriminate against those who usually discriminate against them”, “The integration process has to be bidirectional”.

The two-way communication It is established when the protagonists can send and receive messages simultaneously. Take the case of two friends named Charles Y John who are talking on the phone. Both can speak when they want, and in turn listen to what the other says. This communication is bi-directional as messages flow in two directions (from Charles to John and of John to Charles).

It is important to note that communication does not always develop in this way. A newspaper printed on paper generates a one-way communication because it issues its message (the news printed on their sheets) without feedback being able to occur.

A bidirectional path, on the other hand, allows simultaneous circulation in two senses. The streets that have a hand and a counter are bidirectional; for example: it is possible to go north or, on the other hand, south.

The bidirectional processes they also contemplate this duality. Suppose two countries establish a free trade agreement. The country R, in this way, you can export your products to the country S without paying taxes or duties. In turn, the country S can export to the country R without having to pay fees. The export and import of goods duty free between both nations is bi-directional.

In the field of telecommunications, it is called duplex to a system that can give rise to bidirectional communication, that is, it is capable of accepting the sending and receiving of messages simultaneously. There are certain levels that condition this transmission capacity:

* a half physicist who can perform such a task in two opposite directions;

* a transmission system that can send and receive at the same time;

* a communication standard or protocol used by terminal equipment, that is, each one at the ends of the system.

BidirectionalA possible classification of these two-way communication systems consists of evaluating their ability to transmission, depending on whether it is partial or complete, and this gives rise to the following three terms: simplex, half duplex Y duplex, the last two being “partial” and “complete”, respectively.

Today, most of the networks Communications systems are based on this model to allow a sending channel and a receiving channel to exist simultaneously. To make a system work in this way it is necessary to use different frequencies (what is called frequency multiplexing) or separate cables.

In big cities, it is common for people to hire alarm systems to protect your homes and offices. Unlike the basic protection that existed in the past, which simply sounded a siren when a door was opened, for example, modern technology allows installing different motion detectors that cover large areas inside and outside the building. In this context we can speak of unidirectional and bidirectional systems.

While the former are only capable of sending information to the central when the detector perceives movement in the customer’s home, the bidirectional ones allow operators to make various queries from the central, to make sure that the equipment works properly and that it is not manipulated or altered by their owners. This reduces the number of scams and maximizes protection for those who want to take advantage of the service legitimately.
