As its name suggests, HTML is a collection of formatting commands that create hypertext documents--Web pages, to be exact. When you point your Web browser to a URL, the browser interprets the HTML commands embedded in the page and uses them to format the page's text and graphic elements. HTML commands cover many types of text formatting (bold and italic text, lists, headline fonts in various sizes, and so on), and also have the ability to include graphics and other nontext elements.
HTTP - hypertext transfer protocol
The protocol used to transmit and receive all data over the World Wide Web. When you type a URL into your browser, you're actually sending an HTTP request to a Web server for a page of information (that's why URLs all begin with "http://"). HTTP1.1, the latest version, is currently undergoing revisions to make it work more efficiently with TCP/IP.
icon
A small picture or image that represents an object, a folder, or a program. Clicking or double-clicking icons launches programs, opens windows, and executes commands.
ISP - Internet Service Provider
Once upon a time, you could only connect to the Internet if you belonged to a major university or had a note from the Pentagon. Not anymore: ISPs have arrived to act as your (ideally) user-friendly front end to all that the Internet offers. Most ISPs have a network of servers (mail, news, Web, and the like), routers, and modems attached to a permanent, high-speed Internet "backbone" connection. Subscribers can then dial into the local network to gain Internet access--without having to maintain servers, file for domain names, or learn Unix.
JPEG - Joint Photographic Experts Group
This file format for color-rich images was developed by the Joint Photographic Experts Group committee. JPEG compresses graphics of photographic color depth better than competing file formats like GIF, and it retains a high degree of color fidelity. This makes JPEG files smaller and therefore quicker to download. You can choose how much to compress a JPEG file, but since it is a lossy format, the smaller you compress the file, the more color information will be lost. JPEG files can be viewed by a variety of downloadable software on both the PC and Mac.
LOSSY
Graphics files are big, and most file formats (such as BMP, TIFF, PICT, and PCX) are inefficiently coded, so they are larger than they need to be. So how do graphics programmers save disk space? They develop compression techniques. Graphics compression techniques fall into two camps: lossless and lossy. Lossless techniques throw away redundant bits of information without affecting the quality of the image. Lossy techniques, such as JPEG, crunch files down smaller, but they throw out image quality in the process. Most of the time, however, you can't see the difference in image quality unless you try to print the graphics on a professional imagesetter.
Kernel
Modern operating systems are typically built in layers, with each layer adding new capabilities, such as disk access techniques or a graphical user interface. But the essential layer, the foundation on which the rest of the operating system rests, is typically called a kernel. In general, the kernel provides low-level services, such as memory management, basic hardware interaction, and security. Without the kernel, your system would stop.
MP3 - MPEG-1, Layer 3
MP3 is a codec that compresses standard audio tracks into much smaller sizes without significantly compromising sound quality.
*codec (coder/decoder or compression/decompression algorithm) As the name implies, codecs are used to compress and decompress various types of data, particularly those that would otherwise use up inordinate amounts of disk space, such as sound and video files.
OCR - optical character recognition
When your computer gets a fax or scans in text, all it sees are graphical bits on a virtual page. That text is not usable, searchable, or editable. If you pass the page through an OCR program, the software converts the shapes on it into a text document. However, few documents are perfectly recognized and the errors are frequent if the type is small or the scan unclear. But the conversion is more often faster than typing text manually.
OS - operating system
A computer by itself is essentially dumb bits of wire and silicon. An operating system knows how to talk to this hardware and can manage a computer's functions, such as allocating memory, scheduling tasks, accessing disk drives, and supplying a user interface. Without an operating system, software developers would have to write programs that directly accessed hardware--essentially reinventing the wheel with every new program. With an operating system, such as Mac OS 9 or Mac OS X, developers can write to a common set of programming interfaces called APIs (application programing interface) and let the operating system do the dirty work of talking to the hardware.
