Wireless network connections, commonly known as Wi-fi,
are beginning to gain popularity. In airport lounges,
cafes and business hotels, you may be able to sit right down and
tap into the web. In fact, soon you could even stop for some fast
food with a fast connection – McDonald’s has signed
on to test Wi-fi in some of it urban markets.
A couple of things to note - First, not all networks
are created equal. Similar to your home network, you may be required
to be a subscriber. (Some providers are joining forces to create
broader coverage.) Second, when on these public networks, don't
use credit card information or passwords. Until security moves
to the next level, your private information can be snatched, quite
literally, out of thin air.
