1GB DDR Dual Channel Memory
Heh. Oh boy; a P4 and a gig of DDR1. Happy days...(NOT).
The thing about Puppies - and TBH, this applies to every distro regardless - is that the quoted size is ALWAYS that of the ISO file. Everybody conveniently overlooks the fact that most of 'em, when unpacked & installed, usually occupy 2½-3 times that space. Even veteran Puppy users are frequently guilty of this in their enthusiasm to recommend it.
OK; in "our Pup's" case, she will (if possible) fully load into RAM and run from there.....and because the entire thing runs from RAM - the fastest component of machines of that generation - you need to have sufficient RAM for this process to work. Which your Gateway, in its present configuration, simply doesn't have.
If that's the P4 I think it probably is, it has the 800 MHz FSB (front side bus) and H/T - which means it'll behave like a dual-core - but even though it runs at 3.4 GHz it'll STILL be as slow as molasses on a cold day.......because it's stuck with only SSE2s. And because it's 32-bit only, as m'colleague
@Brickwizard says, you'll be distinctly limited in what you can run on it.
Most major distros - including Canonical with Ubuntu - have long since dropped 32-bit builds and gone 64-bit only.......but then, 64-bit home systems
have been around for about 20 yrs at this point. It's hardly "new" technology any more.

The reason I won't recommend Puppy to new Linux users is quite simple; despite being simple and easy-to-use, if said noob starts with Puppy as their first distro, then later wants to try a mainstream release, because Puppy is rather different to standard Linux they'll end up having to re-learn a lot of stuff all over again......and I don't think it's fair to put new users in that position.
I always recommend going with a easy-to-use mainstream distro like Mint, cutting their teeth on that and getting used to how Linux works for a while. If, after that, they're still curious about Puppy, they'll be in a rather better position to comprehend the differences AND why/how Puppy works the way she does.
