Well, for one thing, they aren’t yummy and delicious. Internet cookies are tiny files that are designed to make your user experience a bit friendlier. For example, if you regularly visit a clothing Web site and have created your own “virtual model” for trying on clothes and seeing how they might look on you before you buy, then you wouldn’t want to go through the hassle of recreating this model, complete with measurements, weight, and personal characteristics each time you visited the site, right?
A cookie solves that for you. This tiny file resides on your computer. The next time you visit the Web site, the cookie allows all of your preferences to be displayed on the Web site. This includes personal preferences as well as data that you’ve previously supplied such as credit card information, phone numbers, and addresses. In addition, the cookie tells the Web site owner a bit about your computer such as what your IP address is, browser type, and where you came from (such as a referral source).

Another type of cookie involves advertising. Web sites regularly feature advertisements. These advertisements place tracking cookies on your computer and are not designed with your convenience in mind. Instead, these advertisements are often part of a huge network of ads. Your single cookie with its own unique identifier is recorded any time you land on a Web site that also uses the advertising network. For example, let’s say you visit twenty web sites, fifteen of which participate in this advertising network. The advertising network knows that you visited these fifteen different websites.
So what? Over time, the advertiser builds a database of your interests based on the types of sites you visit. From this information, the advertiser makes assumptions about your Internet habits and interests and begins serving up targeted advertisements. Privacy concerns surround this type of cookie usage.
Fortunately, your Web browser has settings for accepting or rejecting cookies as well as an area where you can delete cookies. To adjust cookie settings in Internet Explorer, go to Tools, Internet Options, and click on the Privacy tab. From here, you can adjust how your browser deals with cookies. To delete existing cookies, go to the General tab, Browsing History, Delete, Delete Cookies.
Internet cookies have their good and bad points. They’re great for personalized Web site experiences but terrible when used to track surfing behaviors. Set your computer’s Web browser up so that you have adequate protection against the bad cookies and yet can still enjoy returning to legitimate Web sites. Periodically delete all cookies from your computer.
