You'll need a router to hook up more than one computer to the internet and there's a wireless and wired way to do that. With a wireless router you'll hook it up to your modem and it will broadcast a wireless network which you will be able to log onto anywhere in the house. With the other option you will have to run a cable to the computer that isn't located next to the modem. Now assuming that the two computers are towers, they probably won't have a wireless card and won't be able to connect wirelessly unless you go to your local electronics store and buy one. At my house it wasn't a big deal to run the cables through the walls, and we use a Microsoft base station. It works good and requires no set up, all you have to do is plug it in. With wireless it can be a little bit difficult to set up, depending on the router, and they're also more expensive (I've also never purchased the wireless antennae for a computer but would expect it to cost not too far under $100 [you'll only need one]). If you have a laptop this is certainly the way to go, since you'll be able to access the internet anywhere in the house. My suggestion if you go wireless is to have someone you know who's 'computer savy' to help set it up.
What you need,
Wireless; wireless router, (if you your computer doesn't have a wirless card) a wireless antennae.
Wired; a base station, an internet cable running for the basestation to the both computers.
it depends
Each computer has to be connected to the internet
No, you will have to have separate license key for each computer.
No you cannot. It is a two-player game played on the same PC. If you want multiplayer on different computers, try Boxhead Bounty Hunters.
If you do not have corporate license, you have to get a separate copy for each of your computers.
Sort of the same as the difference between a printing press, and the truck that delivers papers to homes. Ethernet is a good way to connect computers together in a local area network, or LAN, so they can communicate with each other or each connect to a separate computer or router. Internet is a good way to connect people to usable information.
No, there is not.
no there can not the whole point of a computer is the internet
Its when you have a separate line that is only for internet going to a building.
That depends on the speed of the internet connection. On a 54 Mbps wireless connection, the speed of the connection is diminished slightly by only two computers. For a 54Mbps wired connection, the number of computers that would effect the same speed loss, is about five. In neither case ids the quality effected.
Because, The internet is the biggest world-wide communication network of computers. It has millions of smaller domestic, academic, business, and government networks, which together carry many different kinds of information.
These days each desktop computer has a separate internet address bypassing the need to have everything sent through a ring of computers or token ring system. The internet is based on a form of interlinked computers that means information sent from one computer find its way through whatever links it needs to another computer regardless of where those computers are.
