COMPUTER FUNDAMENTALS

Detailed explanation-1: -A compiler takes the source code as a whole and translates it into object code all in one go. Once converted, the object code can be run at any time. This process is called compilation . All of the object files used in a program must be combined before the program can be run.

Detailed explanation-2: -Compiler: The language processor that reads the complete source program written in high-level language as a whole in one go and translates it into an equivalent program in machine language is called a Compiler. In a compiler, the source code is translated to object code successfully if it is free of errors.

Detailed explanation-3: -Compilers translate code all at once and the processor then executes upon the machine language that the compiler produced. If changes are made to the code after compilation, the changed code will need to be compiled and added to the compiled code (or perhaps the entire program will need to be re-compiled.)
