Customer: OK, that sounds complicated enough! And can I access the Internet automatically with this PC?
Assistant: Well, you need a computer and a modem - a device that connects your PC to the telephone line. You'll also need an account with an Internet Service Provider, or ISP - that's a company that offers connection to the Internet for a monthly fee.
Customer: OK, that sounds easy, but what if we have several computers in different rooms. How can I connect them all to the Internet?
Assistant: In that case, the best choice is a wireless router with a built-in modem. It's a device that links various computers over a network and will connect everyone in your family to the Internet without using cables. New computers include wireless support but if any of the computers are old, you'll need a Wi-Fi wireless adapter.
Customer: I'm sorry, but what does Wi-Fi mean exactly?
Assistant: Wi-Fi is short for Wireless Fidelity and refers to a technology that uses radio waves to communicate data over medium range distances.
