Symbol, gesture, sign whose function is to warn or inform about an issue
The term Signal is designated as that symbol, gesture, or other type of sign whose function is to warn or inform about any issue. Therefore, what the signal does is replace the written word or language, as appropriate. They generally respond to conventions in society or in groups, so they will be easily understood and interpreted by almost everyone..
And it is important that it is so to avoid complications in terms of its not understanding, decoding. Let us think of someone who travels to a country and does not know the language spoken there, the traffic signs, which have an international convention will allow that person to rent a car and drive without problems on a highway because the traffic signs are precisely images that when you see them your message is already decoded.
Located in visible places and will show different colors and shapes
When the sign represents a symbol, it will be located in visible places and will show different colors and shapes, generally these striking so that they awaken the attention of people if they have the function of communicating highly important information for life and health care. .
In the case of signals made through gestures, they are made by people through their hands, arms, legs. Likewise, the signals can be represented in other ways, for example with flags or using some type of light, such as lighthouses on the coasts, especially when it comes to maritime navigation.
Various types of signals
So, from all of the above, the existence of various types of signals can be inferred, including: safety sign, traffic sign, maritime flag signs, danger signs, railroad signs, analog signs, digital signs and computer sign.
Meanwhile, of all these, the most common with which we find almost daily are the traffic signs and danger signs. The former are signs placed on poles or painted on streets or highways to impart the information that both motorists and pedestrians need in order to travel safely.
In addition, to avoid that even the language is a barrier to understanding them, traffic signs are manifested in all parts of the world through symbols instead of words.
And those of danger are those that are used to warn people who are or are about to enter a dangerous area for their integrity, for which they must avoid it or, failing that, if they cannot do so, take the appropriate precautions.
There are public places or private spaces in which people or any other living or material good can be plausible of being at risk of life. So, an effective way to prevent accidents or any other complex situation is to use danger signals, because their clear objective is to alert people who are close to or within a dangerous zone. Then, with that knowledge, they should avoid it or take the precautions and protections that the case demands.
But although the commented reference lines is undoubtedly the most popular use of the word, we must emphasize that there are others that have also become popular.

And on the other hand to the amount of money that is advanced or advanced in some contracts or at the request of making a purchase is designated with the signal term. For example, I left $ 300 as a down payment for the pharmacy cabinet I purchased.
Coverage field in cellular telephony
In these times where the cell phone practically brings together all the telephone conversations that people make, the signal term is certainly popular since it is called the field disposition, of antenna coverage to make a call to another mobile , to a landline or to send a text message to another cell phone.
When there is no signal directly, because you are in an area of no coverage of the company or where there is no antenna or when the signal is poor, as in some areas or public buildings, establishing communication via cell phone is certainly difficult.
A hint
And also the word signal is widely used as a synonym for an indication of something. That is to say, through the succession of something, of a conduct, action or behavior, an issue is taken into account. "The presence of my brother was a sign that something bad was happening with my father."
