Using memory cards

[birdcage]

Hey all, Birdcage here. Well, I be new to emulation...making my own Let's Play series on Youtube. But, one thing I've not been able to understand...memory cards.

Is it an actual PS1 memory card, hooked up to your computer? Or can you use your computer's HDD as a memory card?

If anyone could explain, or link a guide, or something, that'd be awesome
