Hi I'm Gary Malec, and in this video I'm going to talk to you what a USB hub is. Most laptops these days will come with a lot of USB supports. But pretty much everything these days is powered by USB, they don't even use wall outlets anymore on a lot of things, so. If you don't have enough you can buy a hub that takes up- it's pretty much like an extension cord, it'll take up one spot on your USB and then it'll turn into four. I particularly like it because I like to play old video games and you can put four controllers right in one spot and then plug your laptop into the TV. So these things have a lot of uses, they're not that expensive, so if you're running out of USB spot this is the way to go.
