Introduction of Language Processors

Assembly language is a machine-dependent yet. That is being used to represent instruction in it. They are not directly understandable by machine and high-level language is machine independent.

If the computer understands instruction in machine code ie:- In the form of 0 and 1. It is a tedious task to write a computer program directly in the machine code. The program is mostly written in a high-level language like- Java, Python, C++.. etc are called source code.

These source code cannot be executed directly by the computer and must be converted into machine language to be executed.

Hence, a special transfer system software is used to translate. The program written in a high-level language into machine code is called language processors. And the program offer translated into machine code is called object program/object code.

Language processors:-

A language processor is a special type of computer software. That has the capacity of translating the source code into machine code.

The language processors can be divided in the following three parts:-

1. Compiler:-


The Language processors, That reads the complete source program written in high-level language as a whole in one go and translate it into an equivalent program in the compiler.

Ex:- C, C++, Java.

2. Assembler:-


The Assembler is used to translate the program written to assembly language into machine code.

               Source code———> Assembler—————> Object code

3. Interpreter:-

The translate of Single statement of source program into machine code is done by language processors and execute it immediately before moving on to the next line is called Interpreter
