The technique employed is to encase the information in special markers (called tags) which tell the WWW applications how the text is to be interpreted.
Internet—A vast collection of interconnected networks that all use the TCP/IP protocols (evolved the late 60’s and early 70’s). The Internet is a global collection of computer networks interconnected with computer networks linked around the world. The Internet has two major meanings – First, the whole constellation of resources that can be accessed using Gopher, FTP, HTTP, telnet, USENET, WAIS and some other tools. Second, the universe of hypertext servers (HTTP servers) which are the servers that allow text, graphics, sound files, etc. to be mixed together.
ISP (Internet Service Provider)—A company or an institution that provides access to the Internet in some form, usually for a monthly fee.
Java—Java is a network-oriented programming language invented by Sun Microsystems. Java is designed for writing computer programs that can be safely downloaded to your computer through the Internet. Smaller Java programs (called “Applets”), can include functions such as animation that can be added to a Web page.
Kilobyte—A thousand bytes, technically 1024 bytes.
Login—The account name used to gain access to a computer system.
Lurking—Reading chat, forum, or newsgroups messages and not responding to them.
Macintosh (MAC)—a type of personal computer, manufactured by Apple Computer, and it is not a PC.
Megabyte—A million bytes technically, 1024 kilobytes.
MPEG (pronounced M-peg)—MPEG stands for Moving Picture Experts Group. MPEG is the name given to a set of standards used for coding audiovisual information (i.e., movies, music, and video) in a digital compressed format. The major advantage of MPEG compared to other video and audio coding formats is that MPEG files are much smaller for the same quality. Current standards that exist include, MPEG-1, MPEG-2, MPEG-3, and MPEG4.
MOV—To view a file with the .mov extension, you need QuickTime multimedia technology to run it. MOV files can be movie clips, such as Video for Windows’ AVI files, or still images, such as GIFs.
Netiquette—Etiquette for the Web. It can be summed up as, “Be polite and don’t waste computer resources.”
