ExpressCard

ExpressCard is like a little door on the side of your computer where you can plug things in. It's kind of like the way you plug in your phone charger or headphones into your phone. But instead of plugging in just one thing, you can plug in a whole bunch of different things like a special kind of memory card, a fancy microphone, or even a TV tuner. It helps you do more things with your computer and have more fun.
