It is also called binary language as it consists of tow numbers 0s and 1s. Middle le ve llang uag e : Asse m bly lang uag e : it is the very next level of programming language introduced after machine language.

- 5. Language Translators Asse m ble r: This type of translators only works for assembly language, it converts program written in assembly language into machine language. Co m pile r: They are program which convert the program written in high level language into machine language whole program at a time before execution. Inte rpre te r: They are program which convert the program written in high level language into machine language one instruction at a time.
- 6. Source Program and Object Program Source Program: The program that is written in any language other than binary language is called source program and it is so called source code. Object Program :The program that is in binary language is called object program and this program is also called object code.
