What is a Language?

               Language is a communication system of human.

 What is a programming Language? 

            A programming Language is a formal constructed language design to communicate instruction to a computer or machine.Programming language is used to create programs to control the behavior of a machine. 

Types of programming Languages

  1. Low level Language
  2. High level language


  1. Low level language 
  • Low-level language is a programming language that deals with a computer's hardware components
  • Low-level languages are designed to operate and handle the entire hardware and instructions set architecture of a computer directly.

There are two types of low level languages

  1. Machine language 
  1. Assembly Language
  1. Machine Language

           Machine code or machine language is a set of instructions executed directly by a computer's central processing unit (CPU). Each instruction performs a very specific task, such as a load, a jump, or an ALU operation on a unit of data in a CPU register or memory. Every program directly executed by a CPU is made up of a series of such instructions.

  1. Assembly languages 
  • An assembly language is a low-level programming language for microprocessorsand other programmable devices. 
  • Assembly language implements a symbolic representation of the machine codeneeded to program a given CPU architecture. 
  • Assembly language is a mathematical and logical symbol that used tocommunicate to the computer.
  1. High level language

              High-level language is a computer programming language that is designed for a specific job,                 and is easier to understand. Its source code is written in human understandable language.                       However, for a computer to understand and run a program created with a high-level language, it               must be compiled into machine language.

What is a compiler? 

Compiler is software which converts source code into machine code. It convert whole document. 

What is an Assembler?

Assembler is software which converts source code written in assembly language into machine code. It converts line by line. 

What is interpreter?

Interpreter is a computer program that directly executes, i.e. performs, instructions written in a programming or scripting language, without previously compiling them into a machine language program

Difference between Compiler and Interpreter 





Compiler takes Entire program as input

Interpreter takes Single Instruction as input


Intermediate object code is generated

No intermediate object code is generated


Conditional control statements is executes faster

Conditional control statements is executes slower


Program not need to be compiled everytime

Ever time higher level language program converted into low level language


Errors are displayed after entire program is checked

Errors are displayed for every instruction interpreted (if any)
