The term operator , whose origin is found in the Latin word operātor ( "he who does" ), has several uses and meanings. It is used, for example, to name the subject who is in charge of carrying out communications that are not automatic from a telephone exchange or the expert who controls technical devices : “I am waiting for the visit of the electric company operator since I am without service.” since two days” , “Operator, please contact me with commercial management” .
In the audiovisual industry, an operator is one who is trained to direct a camera and take images professionally. Also known as an operator is the person in charge of managing the projector and the sound equipment of the films. An example of these meanings would be the following: “The producer of the television program ordered the camera operator, who was attending the political meeting live, to capture the images of the leaders who were presiding over it.”
A tour operator , meanwhile, is a wholesale company that is responsible for contracting accommodation services, restaurants, transportation companies, etc. and resells them to the end user, often putting together vacation packages.
Boolean operators
In addition to all of the above, it must be emphasized that in the field of computing and specifically in the world of the Internet, what are known as Boolean operators become very important. And these are what allow us to carry out the search for a term or a topic in an exact way that allows us to obtain the results we expect.
Specifically, we can establish that the aforementioned operators are four:
And . This is used to determine that we want to locate all the records. So, for example, if we write “directors and actors” we will get records that have all those concepts.
Or . What this operator offers us is the opportunity to find records that have the first term that we entered or the second but not both at the same time.
Not . By using this option we will find results where the first element that we have written appears but not the second. Thus, using the example cited, we will be offered records that contain directors but not actors.
Xor . With this Boolean operator, what we will achieve is that we will be given results that contain some of the terms that we have established but not all of those exposed.
Position or relational operators, which are used to find numerical expressions, are other fundamental operators in any search of this type.
The term in mathematics
In the field of mathematics , an operator is a symbol that denotes a set of operations that must be performed on a certain number of operands. The operator can also be a function that acts on other functions.
There are various types of mathematical operators. Logical operators provide a result based on the fulfillment, or not, of a certain function. Typically, their values can be parameterized with the numbers 0 and 1 . This allows computer programming to use these operators to combine logical values ( True/False ) and introduce functions to programs .
Condition operators are those that link a term A with another B to establish their hierarchy, equality or other link.
