Translators. Compiler vs Interpetator

How can we convert program code into binary so that a computer can understand it? 

Translators translate high-level language programs into machine language programs that the central processing unit (CPU) can understand.  It also detects errors in the program.

Different Types of Translators

There are 3 different types of translators as follows:

1. Assembler
2. Compiler
3. Interpreter

We consider two types: Compiler and Interpreter.

Worksheet to video

Compiler

A compiler is a translator used to convert high-level programming language to low-level programming language.  It converts the whole program in one session and reports errors detected after the conversion. The compiler takes time to do its work as it translates high-level code to lower-level code all at once and then saves it to memory.

Interpreter

Just like a compiler, is a translator used to convert high-level programming language to low-level programming language. It converts the program line by line and reports errors detected at once while doing the conversion. With this, it is easier to detect errors than in a compiler.
