A program is a sequence of instruction written In a language that the computer can understand and there by process .The individual set of such sequences of instruction or a collection of such set can be turned as programs .

Programming Languages is a set of Programming Languages is a set of grammatical rules for instructing a computer grammatical rules for instructing a computer to perform specific tasks. Example of to perform specific tasks. Example of programming Language are BASIC, C,C++, programming Language are BASIC, C,C++, COBOL, FORTRAN and Pascal. Each COBOL, FORTRAN and Pascal. Each language has a unique set of keywords and a language has a unique set of keywords and a special syntax for organizing program special syntax for organizing program instructions programming language can be instructions programming language can be divided into two levels.divided into two levels.

Page 6: Computer project work  [viii]2008 09

Low Level Language These language

are directly linked with computer can understand these languages and therefore , are called Low Languages.

High Level Language These Languages are

much closer to human language code and were developed to make programming easier. The dependency of these languages is on interpreter and complier so that the computer can understand and process whatever is instructed in High Level Language.

A Complier is a program that translates a source program written in a high Level Language [such as a] into machine code for the appropriate computer hardware. The Program can then be executed on any computer without the need of complier. A complex reads the complete program checks for the error and reports it after the error have been removed it converts the Program into an executable program which can be run on any machines without the need of Complier.
