ISP

Short for internet service provider, an ISP owns and operates all of the equipment (telephony, digital cable, servers, etc.) that allow you to connect to the internet from your home or office.

Most ISPs sell access to their services for a small monthly fee, which you can access by connecting to your ISP’s computer network through a phone or cable line.

Hexadecimal

The hexadecimal (base 16) number system used for Web-page design consists of 16 unique symbols:0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.

For example, the decimal number 15 is equal to the hexadecimal number F. In HTML, an RGB color can be designated by
RRGGBB
with the first two numerals representing the amount of red, the second two the amount of green, and the last two the amount of blue. If you wanted your background to be red, you could write the code for a body background color as
<body bgcolor="#FF0000">
Black is the absence of all color and white is the presence of all color, so in hexadecimal, black is at the bottom of the system (no red, green, or blue:
#000000
and white is at the top (the maximum amount of red, green, and blue:
#FFFFFF

Rollover


Rollover is a widely used dHTML effect, its name originally coming from Macromedia Director’s scripting language, Lingo. Internet Explorer 4.0 first supported rollover effects through Cascading Stylesheets (CSS) without requiring extra code. The dHTML mouseover works by switching the visibility of a CSS layer from hidden to visible and back again. This kind of rollover allows you to swap in text or plug-ins, as well as alternate back and forth between images to create the effect. The 4.0 implementation of CSS and JavaScript is not consistent, however, so the code can get ugly.

XML

Extensible markup language is used primarily for web pages. XML allows the author to extend and customize basic HTML formatting by creating proprietary tags and text behaviors. XML is meant to emphasize intelligent and logical formatting within technical documents in order to streamline searching and categorizing, and to ensure total cross-browser compatibility.

FTP for Beginners

It was in the dark ages of the Reagan era when I logged my first encounter with the File Transfer Protocol. I was involved in some nefarious video game-trading ring of the innocently naive variety, and a friend of mine had that hot new copy of Vladivostok Putting Challenge that I wanted oh so badly. The only problem was that he lived all the way on the other side of Orange County. Being too young to drive, neither of us had access to a car, and snail mail was just too darned slow. I wanted to lay down sloping fifteen-footers and rub it in the face of the Reds today, not in a week. “No problem,” my friend assured me. “Just log in to my server and grab it with FTP.”

“FTP? What is that?” I asked. My friend let out an Oscar-worthy sigh and gave me the quick run down of the Internet protocol that would forever transform my life.

Last I heard, my friend is collecting Galaxie 500s in Michigan, so calling him up with your FTP questions isn’t really an option anymore. Lucky for you, I’m here to give you a holier-than-thou sigh of my own and send you down the dharma path. For those of you who are entirely new to this whole game, we’ll start with a basic primer on the most comely of acronyms.
