Cookies<br />
A cookie is few lines of text that is part of an http transaction. It was originally invented<br />
to help you navigate the web. When you are connected to a particular Internet site, the<br />
server doesn't actually remember you from one instruction to the next, much less one<br />
visit to the next. <strong>The</strong> server therefore sends you a cookie, and uses the information<br />
contained therein to remember your preferences (without bothering you), keep track of<br />
items in your shopping cart, or simply count you accurately as a single visitor and track<br />
your navigation through the web site..<br />
When you retrieve data from a site using a cookie, the server transmits the cookie to<br />
your browser along with the rest of the html document requested. Your browser stores<br />
the text on your hard disk. When you later retrieve the same Web page, the cookie is<br />
transmitted back to the server. <strong>The</strong> latter may then send an updated cookie.<br />
You can delete any cookies that are on your disk without harm. However, if you set<br />
your browser to refuse all cookies, then you may be unable to use certain sites to their<br />
full capabilities.<br />
Because the rendering engine used in web browsers is also woven into email clients<br />
and Usenet news readers, it is possible for someone who sends you email or posts and<br />
html article to a newsgroup to cause your machine to access images on his site when<br />
your read the mail or the article. If the sender customizes the URL in the message so that<br />
it contains your email address, he will also know exactly who you are.<br />

CSS<br />
Cascading Style Sheets (CSS) is an Internet tool that separates the presentation from the<br />
structural markup of a Web site. CSS keeps the structure of a document lean and fast<br />
while controlling the appearance of its content. (Frequently asked questions regarding<br />
CSS).<br />
Domain Name System (DNS)<br />
<strong>The</strong> Internet DNS gives names to locations on the Internet, and consists of a hierarchical<br />
sequence of names, from the most specific to the most general (left to right), separated<br />
by dots, for example nic.ddn.mil.<br />
DNS is also a system that translates a domain name from letters (eg.<br />
www.google.com) into a numerical IP address (e.g. 204.71.200.73). Letters make it<br />
