language is the source of communication. like human language to communicate with computer it is necessary to know about computer language.

here are some rules to justify a language. human language also have some grammatical rules and computer also.

The rules to write a language is known as syntax.

Computer language

computer is an electronic machine and it understand only machine language.this language is in binary form.

binary means two and hance this language have two digits 0 and 1. all operations are represented by these digits. 1 indicate presence of impulse and 0 indicate absence.

computer language is basically divided into three categories:

1. machine language (0,1)

2. High level language (close to human)

3.machine language

1.H I G H LEVEL LANGUAGE

high level language is computer language which is closer to human but far from computers. it uses human sentence like OPEN or PRINT.

computer uses translator to understand these languages. e.g. assembler compiler or interprter.

some examples of high level language :

1. COBOL

2. Fortran

3. c++

4. java

2.ASSEMBLY LANGUAGE

assembly language use special characters to represent information this is machine language but computer use assembler to understand this language.

MACHINE LANGUAGE

machine language is binary language which is represented by two digits 0,1 . it is easily accessible to computer.because computer have binary encoding. like ASCII or BCD.

HISTORY OF BINARY

Binary system. The modern binary number system goes back to Gottfried Leibniz who in the 17th century proposed and developed it in his article Explication de l’Arithmétique Binaire [1] . Leibniz invented the system around 1679 but he published it in 1703. He already used symbols 0 and 1.
