It's actually pretty simple, although I found it confusing too. And, while Yahoo calls them "web beacons", which sounds very nice and acceptable, most people call them "web bugs". Let's say I write a web page, and put it on my web server. Within my web page, I include an IMG tag pointing to a GIF on another server. You then enter the URL to my page in your browser, and view my web page. Your browser will, as part of the process, fetch the GIF from the other server. The other server can keep track of these requests, and set cookies on your browser.
