While I'm no expert of compiler methods and such, even I'm able to
realize what most of these describe.

One pass compiler: a compiler that translates the source unit in a
single pass

Multi pass compiler: a compiler that translates the source unit in two
or more passes

Load and go compiler: not sure, never seen this terminology, unless
you're talking about an interpreter

Optimizing compiler: a compiler that optimizes the translated code,
usually during the code generation phase (?)... it makes the code run
better on the particular architecture it is compiling for (ie using
shifts instead of multiplies, loop unrolling etc...)
[Load and go compiles directly into memory and immediately runs the code.
They used to be quite popular, not any more. -John]
