1.1 WHAT IS A COMPILER?

A compiler is a program that translates a high-level language program into a functionally equivalent low-level language program. So, a compiler is basically a translator whose source language (i.e., language to be translated) is the high-level language, and the target language is a low-level language; that is, a compiler is used to implement a high-level language on a computer.
