Planet Hardware heeft een artikel over netwerken met o.a. info over draadloze netwerk verbindingen en USB Ehternet. Hiet wat USB info:
Right now there are two main forms of USB ethernet connectors, Host-to-Host, and Ethernet-to-USB. Both are ungodly simple to set up, you can have a working network within minutes of opening the box. Host-to-Host adapters are made for connecting 2 PC's, no more. They have a USB adapter on both ends of the plug, and an ethernet decoder box somewhere in the middle of the cord, they have no plugs for going to an outside network, it's basically like a null modem concept. Two main products I've seen to use this approach are the Anchor Chips EZ-Link USB Ethernet kit, and the Belkin USB-to-USB ethernet adapter.
The other method is an Ethernet-to-USB adapter, these are made to connect a computer without an ethernet board to an outside network. They usually comprise of a cable, with a USB connector on one end and an RJ-45 10-BaseT connector on the other end. Very cool idea, if you want a quick and easy network setup to your company or home network that's already running on CAT-5 cabling. Some companies who make these products are Belkin, ADS Technologies, and Peracom, with more out there if you look.
