COMPUTER LANGUAGES
A computer language, also
called a programming language, is a
language used to write and develop
software program for the computer
.Computer language can be classified into two broad categories:
low-level languages and high-level language.
LOW-LEVEL LANGUAGE
Low-level language are of two types: machine language and
assembly language. Low-level languages are machine-dependent. Code written for
one machine might not work for another.
MACHINE LANGUAGE
Machine language is language that the computer understands
and can execute directly without translation. In machine language, each
instruction is written in the form of a long string 0s and 1s.
ASSEMBLY LANGUAGE
Assembly language was the first computer language to use
words made with letters of the English aiphabet.It developed in 1950.In
assembly language,each instruction to the computer is written using a letter
combination that tells the computer where the data is and what to do with it.
HIGH-LEVEL LANGUAGE
The widespread use of
computer by the mid-1950s led to the development of high-level languages.These
languages use English and mathematical symbols to make computer programming simpler.A
program in a high-level language is called a source program.It cannot run directly on
computer.It must be compiled or interpreted first.High-level language programs
are machine-independent.They can be run on different types of computer without
any change.Some examples of high-level language are
BASIC,COBOL,FORTRAN,C,C++,and Java.
