P-code.
FORTRAN
The human-created, editable version has to go through some kind of translation into machine code that the machine can actually run.
Has to execute as a stream of bytes that are instructions in your computer's machine language.
Interpreted Language.
The most conventional kind of language get translated into runnable files of binary machine code by a special program called a compiler.
Are like compiled languages in that the source is translated to a compact binary form which is what you actually execute, but that form is not machine code, instead it's pseudocode.
Compiled Language.
The source code.
Depends on an interpreter program that reads the source code and translates it on the fly into computations and system calls.
Is another compiled language still used among engineers and scientists but years older and much more primitive THAN C.
Program.
