Computer programs are everywhere: from coffee machines and MP3 players, satellites, robots, cell phones, watches, etc. But just as astronomy is more than using telescopes, computer science is more than using computers, it is programming them to tell you exactly what to do.

A programming language is a system structured under a formal language (code) and designed mainly so that machines and computers can understand the computational algorithms written by programmers. Computers only understand binary language (endless strings of numbers 1 and 0), for man it is complex to program computers through the binary system and that is why programming languages ​​were created, the programming language is then in charge of converting the Programmers instructions from a formal language to ones (1) and zeros (0) so that computers and machines can understand and interpret them.

Programming languages ​​can be classified in various ways, there are them by level, and by the way they are executed.

By level

There are high-level programming languages ​​and low-level languages. High-level languages ​​allow a few words to do the same as a low-level language.

Examples of high-level languages: C ++It is a programming language created in the mid-1980s by Bjarne Stroustrup. Currently, C ++ is one of the languages ​​most used by software developers., PythonIt is an interpreted programming language whose philosophy emphasizes a syntax that favors readable code., JavaIt is a programming language designed in 1995 by the Sun Microsystems company..

Low-level language examples: AssemblerIt is a programming language developed in 1950, it is considered a low-level language.

By the way they are run

There are compiled and interpreted languages. Compiled languages ​​require a special program to read the source code and create an executable binary file for a specific platform. Example:C ++It is a programming language created in the mid-1980s by Bjarne Stroustrup. Currently, C ++ is one of the languages ​​most used by software developers., PascalIt is a programming language developed by the Swiss professor Niklaus Wirth in 1970..

Interpreted languages ​​require a program that directly translates the written source code into instructions on the platform on which they are executed. ExamplePythonIt is an interpreted programming language whose philosophy emphasizes a syntax that favors readable code., JavaScript.

Compiled languages ​​are faster, while interpreted programming languages ​​are slower, this because when compiling a program the commands are more understandable to the computer, while when interpreting it the machine must first read the code and scan and convert to step instructions to machine instructions understandable for her.

Currently there are dozens of programming languages, some of the languages ​​used today are php, ASP.net, ActionScript, Ada, PythonIt is an interpreted programming language whose philosophy emphasizes a syntax that favors readable code., Delphi, C ++It is a programming language created in the mid-1980s by Bjarne Stroustrup. Currently, C ++ is one of the languages ​​most used by software developers., Visual Basic, Matlab, JavaIt is a programming language designed in 1995 by the Sun Microsystems company., JavaScript, etc.
