What is wireless networking?

Answer 1

Answer
Wireless networking allows you to connect several computers in your home without using hard wiring. This is especially useful in providing internet and email capability to each computer. You will need an internet service provider such as your cable or telephone company, a cable or DSL modem to receive and transmit to the internet, one wireless router and wireless cards for each computer. The wireless cards are not difficult to install, but it would be best to ask a knowledgeable friend or co-worker to help you. Visit your local Fry's Electronics, BestBuy, Staples, OfficeMax, CompUSA or similar retailer and ask for wireless network assistance. You should be able to create your own wireless network for about $100 depending upon how many computers you are linking.
