Computer language or programming language is a coded syntax used by computer programmers to communicate with a computer. Computer language establishes a flow of communication between software programs. The language enables a computer user to dictate what commands the computer must perform to process data. These languages can be classified into following categories

1. Machine language

2. Assembly language

3. High level language

Machine Language

Machine language or machine code is the native language directly understood by the computer’s central processing unit or CPU. This type of computer language is not easy to understand, as it only uses a binary system, an element of notations containing only a series of numbers consisting of one and zero, to produce commands.

Assembly Level

Assembly Level Language is a set of codes that can run directly on the computer’s processor. This type of language is most appropriate in writing operating systems and maintaining desktop applications. With the assembly level language, it is easier for a programmer to define commands. It is easier to understand and use as compared to machine language.

High Level Language

High Level Languages are user-friendly languages which are similar to English with vocabulary of words and symbols. These are easier to learn and require less time to write. They are problem oriented rather than ‘machine’ based. Program written in a high-level language can be translated into many machine languages and therefore can run on any computer for which there exists an appropriate translator
