WWW Everyone
|
- Browser:
- A WWW client program that can "speak" at least HTTP and gopher, and can
interpret HTML documents. Examples are Mosaic (for Windows, X Windows, and
Mac) from NCSA, Lynx (UNIX/VT100) and DosLynx (DOS) from the University of
Kansas, and Cello (Windows) and Viola (X Windows) from Cornell. Mosaic for
Macintosh and Mosaic for Windows are included in our Network Services Kit.
- CGI:
- Common Gateway Interface. A protocol used by HTTPD to channel information
from a browser to a custom program (such as a database interface) and to return
the result of the custom program to the browser.
- GIF:
- Graphic Interchange Format. A format for pictures that many browsers can
display. Other such formats might include JPEG, MPEG, and PostScript.
- Gopher:
- An Internet information distribution system developed at the University
of Minnesota. The term Gopher can refer to a Gopher client program, to the
protocol used, or to a Gopher server program, depending on the context.
- HTML:
- HyperText Markup Language, the lingua franca of the WWW. A particular instance
of an SGML markup language, particularly suitable for using hypertext pointers.
- HTTP:
- Hypertext Transport Protocol. The rules by which WWW browsers and servers
communicate.
- HTTPD:
- HTTP Daemon, a WWW server for UNIX written at NCSA. NCSA's WWW server for
MS-Windows is WinHTTPD.
- MIME:
- Multipart Internet Mail Exchange format. Used by many electronic mail systems
(including Eudora) to send sound, video, graphics, binary files, and even
regular text through email.
- Mosaic:
- Sometimes people refer to the WWW as Mosaic, but Mosaic is really a set
of WWW browsers written by the National Center for Supercomputer Applications
(NCSA) at UIUC. There are currently Mosaic Web browsers for X Windows, Apple
Macintosh and MS-Windows.
- SGML:
- Standard Generalized Markup Language. A general formulation for defining
markup languages.
- URL:
- Universal Resource Locator. The particular format for hypertext pointers
used by HTML and WWW.
- WAIS:
- Wide Area Information System. A query system designed by Thinking Machines.
Many Web browsers can query WAIS databases, and thereby do full-text searches
on a variety of information.
- WWW:
- World Wide Web. A network of information servers, principally the ones
using HTTP to serve up HTML documents. The servers are linked, not in any
tight or formal sense, but because an HTML document from one server might
contain pointers to documents on many other servers.
