What is a programming language?
It is a system of rules and orders that allows people to enter commands to computers, machines or robots.
How does it work?
The system developer creates a series of written orders that will make the operating system of the machine to interpret them as commands. There are programs that create programs and each one has its own syntax and semantics, which as in the spoken language the syntax refers to the form the information is presented and the semantics let us know the meaning or signified of that information.
Even though each program has its particular semantic, actually most of them act in the same way throughout a logical composition of lines. This works by giving the computer a code in order to categorize the pulses that it will receive while interacting with human beings. In other words, to program is create the cognitive filters by which the machine will weight, catalogue and store the data that can help her to decide what to do according to logical functions.
In this vein, if the machine was programmed to understand the code "A#1009" as "the red colour" and the code "010010101010011101" as "the pixel", it will give one pixel the red colour, because the programming let the robot “think” what to do if those codes are called.
What is it for?
Programming languages allow us to instruct and “teach” machines to do complex tasks like that goes from calculating universal measurements to pass a film in the screen. According to this, we have to accept that there will be some program languages that can help us better to create data bases while other will perform visual effects and etcetera.
