In the 21st century you can have a radio frequency network device to connect multiple computers together. They call it WiFi. Because instead of using network cables (or wires) they use radio frequency transmitters and receivers, but doesn't it upset the cordless telephone (or wireless telephone which uses radio frequency transceivers) or the wireless Audio Visual distribution box you have connected to the TV (which use radio frequency transceivers.)
The interesting thing is that while they call it wireless technology, there are still wires going from the Wireless access point to the network hub.
Dont get carried away on this new millennium 21st century deal. It is all 20th century technology.
I am happy to accept either radio or wireless as a valid term.
The problem is that the RF spectrum is getting soooooo cluttered with fad technology.
What is worse, I was checking my WiFi router configuration recently and found someone was hyjacking my cable internet connection. (My flat mate turned off the Mac address filtering to connect another fad device.)
