TRANSLATOR/COMPILER/INTERPRETER/LECTURE-4

TRANSLATOR:

 It converts one language to another there are three types of language in computer
(for detail)

• 1.       LOW LEVEL LANGUAGE(L.L.L.): these are those languages in which program is                       written in the form of 0&1. A program written in L.L.L. Is directly understandable by                 computer. The execution of program is fast

             Ø  Drawback is that men cant understand program.

                         Ø Written in low level language

             Ø  It is known as binary language

• 2.       ASSEMBLY LANGUAGE/MIDDLE LANGUAGE: In this language instead of 0,1. A                code called mnemonics code are used so it is easy for user to understand the program.                But the drawback is that it is difficult to remember all the code used to write program.

• 3.       HIGH LEVEL LANGUAGE(H.L.L.) :

          Ø  Easy to understand by user

          Ø  Program is written in English language

          Ø  Butt execution is slow due to conversion from one language too another

     

    Translator is of three types

• 1.       Compiler (for detail)
• 2.       Interpreter
• 3.       Assembler
