Without a doubt, the one thing that has made the Internet such an incredible success revolves around the freedom of choice it offers. In computerese, we call this interactivity. Without it, the Internet experience would be hardly more than an online Yellow Pages or maybe computerized TV. With interactivity, in accessing a Web site, users are immediately confronted with dozens of choices allowing them to wander at will among its offerings. Or, at the click of a mouse, the user can disappear like Spock on Star Trek. And the key to this amazing "cyberportation"? As the Disney song says, "The thingamabob, that does the job" we call the link--or sometimes (if you're really rambunctious) a "hotlink," or "hyperlink." Of course, the other important ingredient in this magical little wonder is the "URL," the Universal Resource Locator, which is, in fact, quite similar to the "online Yellow Pages" I spoke of earlier. Every Web site has a number which is reflected by a lengthy alphanumeric label appearing in quotation marks. Moreover tacked onto the end of this label, making it even longer, can be various pages or images connected with the site, making possible, not only our amazing cyberportation between sites, but within the site as well.
There are three components in a link. First comes the letter "a" which is the abbreviation for anchor. Betcha didn't know that. I'll bet you thought all along it was "anch" or "anc" or maybe just "an." Of course the beloved < comes first. Following the "a" is the reference comment "HREF" followed by "=" and the URL in quotation marks followed by another >. Thus the link looks like:
