They are not to be honest.
But, it is a much faster and direct internet connection. You have much less of a chance of being disconnected. They are very good for online gaming as you get smooth gameplay.
But you need to be close to your router/modem unless you have extenders or if you have managed to get the wire to go through a wall.
because it is . ;)
Mostly because of security issues and EMI.
Wired networks have a wire that connects them to an internet port, wireLESS networks do not.
No, wireless networks tend to be slower than wired networks but they offer more range and you don't need a whole lot of wires. Wireless routers normally have Ethernet ports so you can have a mix of wired and wireless if you desire. The speed difference between the two is barely noticeable, well that's my opinion.
wifi
Ethernet is a wired networking solution. Even thou WiFi resembles a lot of the key distinguishing features of Ethernet, Ethernet is clearly defined as wired by IEEE (Protocol 802.3) while WiFi is defined as wireless (Protocol 802.11).
Wireless or Wired (ethernet cable).
False.
Wireless networks are not laid out using the same topologies as wired networks. They have their own, different layouts. Smaller wireless networks, in which a small number of nodes closely positioned need to exchange data, can be arranged in an ad hoc fashion.
Modem.
Yes the switch is called a router and it can be wireless or wired with ethernet cables. I use my wireless router as a wired router because it also includes four ethernet cable connections in the back.
You can connect your Xbox by wireless or wired (ethernet).
