Possibly an easy question:

What is the difference between using Terminal, X11, & Darwin? When using
very computationally intensive programs at the command line, which should
I use?

TIA,

It's like the difference between using a Ford, a Chevy, or the public
highways.

Terminal and X11 both provide ways of using Darwin, which is the Unix
layer of OS X. Terminal is available on every Mac, but X11 is not
available unless you download and install it. Unless you have a specific reason for installing X11 (such as wanting to run a Unix app that
requires it), you may as well use Terminal.

Ummm... they're all completely different things???

Terminal is the application for accessing a shell supplied with OS X.
X11 is a window manager (like aqua, but different), you may use XTerm
within X11 for a similar thing to Terminal.
Darwin is the open source section of OS X.

Terminal is a text mode session that lets you type commands that get executed by a shell program (bash, tcsh, etc.)

X11 is a windowing system used by Unix systems (and, optionally, by OS X). It's responsible for drawing and maintaining windows on a graphical display. Another program, called a window manager (examples: fluxbox, Enlightenment, metacity), is responsible for all of the user interface details.

Darwin is the open source core of Mac OS X. You don't inteact with it directly.

If you're running programs from the command line, you'll probably doing it in Terminal.

These are not comparable entities.

Terminal is an application that allows you to run a command-line
interface to the operating system. The Terminal application uses the
Quartz windowing system and Aqua interface to integrate nicely with
other Mac applications.

X11 is a protocol for creating and interacting with graphical windows
on a display. X11 is the standard graphical interface for unixlike
systems. However, OS X uses Apple's Quartz windowing system, so X11 is optional. There are several implementations available for OS X, and
Apple will include its own as part of OS X 10.3. There is a standard
X11 application called xterm that, like Terminal, provides a
command-line interface within a window. The differences between these
two are minimal. Terminal will do everything you are likely to need to
do. xterm is more comfortable to people working in a more X11-oriented environment on their Mac.

Darwin is the operating system itself on which all the other elements
are built. You may run Darwin alone, without the rest of OS X (Quartz
Aqua etc). Along with X11, this makes your Mac a fairly basic
Unix(like) box.

So, back to your question, if you mean "Is there a difference between
running a program from Terminal and xterm?" then the answer is no.
They are the same thing except for minor user interface differences.

If you mean "Would my Mac be faster at running code on a bare Darwin
system (or in console mode, without any windowing system) than on a
full OS X system?" Then the answer would be probably. But then one
might consider why a Mac rather than other hardware?

Thanks, Eric, and everyone else, for the informative replies!
