What is Interpreter?

interpreter

Has Explained in example machine language is very different that will be in 0 and 1. Machine understand the same, Interpreter will be having an Interpreted language which translates programming code to executable code and gives to the computer. Which runs an executable program and gives the output. But Interpreter goes line by line and execute one by one line. If you face any error in any of line you can change it at your next line.

What is a Compiler?

compiler

The compiler will convert all your program at once to executable code. Executable code is then executed at once in the machine and given output. This concept is very easy instead of an interpreter where you execute line by line. Which makes a programmer in burden.
But if something goes wrong in the program which you have given to compiler it will not stop until complete code is executed.
