COMPILER - INTERPRETER - ASSEMBLER WITH PYQS OF UGC NET EXAM.

 

 

 

TRANSLATOR

·         Translator converts a computer program code from one computer language into another.

·         There are 3 different types of translators as follows:

1.      Compiler

2.      Interpreter

3.      Assembler

 COMPILER

·         A compiler is a software program.

·         Converts high level language into binary code i.e. machine code.

·         Transforming source code into machine code is called compilation.

·         The source code is transformed into machine code in a single step.

 

 INTERPRETER

·         An interpreter is a software program.

·         Converts high level language line-by-line into low level language.

·         If any error is reported, the interpreter stops working.

.                                                                                                                                                      

ASSEMBLER

.·         Assembler is a computer program.

·         Converts low-level language i.e. assembly language into binary code

i.e. machine code.

·         Compilation of the assembly language only.

·         Assembler generates a code for the loader.

·         Assembler is having the mnemonics or symbols in the instruction.
