Compiler, Interpreter and Assembler

Hello Programmers,

every programmer must know about
Compiler, Interpreter and Assembler
as a programmer if we know programming languages, we can't interact with computer directly becauase computer understand Binary Language. In order to communicate with computer we required mediator (translator) between computer and we human . the programme gives instruction in programming language which he knows, then translator convert it into machine language according to instruction.

Translator:
It is System Software( it is nothing but program which it design either to run hardware or our application program) which is use to convert programming language code into machine,

Translator classified into three types

1. Compiler
Compiler is system software which is use to convert programming language instruction into binary language in single step.
i.e when you compile your program compiler check all instruction of a program and generate machine code for that instruction which are syntactically correct, if it is not in correct syntax it will store it somewhere to report as a error at the last of compilation process,

NOTE that compiler just convert the code, compiler is unaware of the logic of the instruction and program.
a) it is fast with high performance.

2.Interpreter
Interpreter is system software which is use to convert programming language instruction into binary language, but in step by step.
i.e when you interpret your program, interpreter check rather it is in correct syntax or not, if it is, it will convert it into machine code, and if it is not correct syntax it will report error that time only and stop the interpretation process. again just like compiler interpreter also unaware of the logic of the instruction and program.
a) It is slower

3.Assembler
Assembler is System software which is use to convert the Assembly language instruction into machine language.

Five Facts about Dennis Richie – The Inventor of C Language

Dennis Ritchie was a renowned American computer scientist. He is best remembered for creating the “C” computer  programming language  and his contributions to the development of UNIX Operating System. Here are some Facts about Dennis Richie that will inspire you. THE CAREER AND EDUCATION OF DENNIS RITCHIE Dennis Ritchie attended Harvard and graduated with degrees in Physics and Applied Mathematics. He began working at Bell Labs in 1968. Later he went on to receive his PhD under the supervision of Patrick C. Fischer. His doctoral dissertation was titled “Program Structure and Computational Complexity.” Ritchie was best known for his work as a key figure in the development of the UNIX operating system. He also co-authored the quintessential book on C, titled “The C Programming Language.” AWARDS GIVEN TO DENNIS RITCHIE FOR HIS WORK Ritchie received several awards throughout his career. In 1983, he received a Turing award for his work on the UNIX operating system. I...
