Most laptops manufactured within the last few years already have one or more USB cable ports. Mine has 4. If your laptop doesn't have one you might be able to get a USB port in a PCMCIA card, but check that your operating system can support it. As I remember, some versions of Windows 98 have a working USB support but anything older may not.
Wireless high speed internet allows you to use your laptop without having it connected to the internet via a cable hook up. You can use your laptop anywhere in the house if you have wireless.
You first need to sign up for an Internet Service Provider (ISP). They will hook you up with service and give you a cable or dsl modem. From there, install the cable or dsl modem, install the software they gave you on your computer, plug in the cable or dsl modem. you know should have HIGH SPEED!
Assuming it has a nic card (ethernet port) you can just use any CAT6 cable (ethernet cable/network cable). Any local computer store should have them.
If you have high speed at home via cable or DSL you can buy a wireless router and connect your laptop wirelessly to it via 802.11. If you don't already have service, you can purchase a cellular modem that will attach to your computer via USB. With that type of modem you can take your laptop anywhere there is cell service and be online.
In my area, Boston, MA, it'd be RCN with $60 for both high-speed internet and cable.
