Answer to Question 1

One way to customize content is to embed programs into Web pages. These programs run when a client device loads the Web page and are called active content. Active content programs can display moving graphics, download and play audio, or implement Web-based spreadsheet programs. Active content can also place items into a shopping cart and compute a total invoice amount, including sales tax, handling, and shipping costs. Active content moves some processing work from the server to the client device. Unfortunately, because active content elements are programs that run on the client device, they can damage it. Thus, active content can pose a threat to the security of client devices.

Answer to Question 2

A Web bug is a tiny graphic that a third party Web site places on another sites Web page. When a site visitor loads the Web page, the Web bug is delivered by the third-party site, which can then place a cookie on the visitors computer. A Web bugs only purpose is to provide a way for a third-party Web site (the identity of which is unknown to the visitor) to place cookies from that third-party site on the visitors computer.
