COMPUTER LANGUAGES
A computer doesn't understand instructions in English or any other human language. We use
programming languages to communicate with computers.
A programming language is a set of words, symbols, and codes used to give instructions to the
computer so it can perform specific tasks. It is also used to write computer programs, i.e. set of
instructions written in a programming language.
The process of writing a program is called programming, and the people who write programs
are known as programmers. There are numerous programming languages worldwide. Some
languages were developed for specific computers; others were developed for specific uses, such
as scientific or business applications.
