UCE --- Unsolicited
Commercial E-mail; polite way of saying SPAM.
Unbound media ---
In a network, this refers to connections that are not implemented using traditional cabling. Instead,
unbound media is wireless--implemented through use of various portions of the radio wave spectrum.
Unimodem driver ---
A universal modem driver supplied by Microsoft as part of Windows 95. The modem driver assumes that
the modem supports the Hayes AT command set (most do).
Uninstalling applications --- When you install an application in Windows 95, it places the necessary files
in many different places on your hard drive. You can't remove all of a program by simply erasing the contents of
its main subdirectory. To uninstall the application--and remove all the files it placed on your hard drive--you
must run a special program that should have been included with the application. Many applications do not include
the "uninstaller" program, although, to be certified under Windows 95, the uninstaller program must be
included.
Universal Naming Convention
(UNC) --- With UNC, you can view, copy or run files on another machine
without assigning it a drive letter on your own. It also means if you are running short of logical drive letters,
you can get to servers that you use only intermittently with a simple command from the MS-DOS Prompt.
UNIX --- A
computer operating system (the basic software running on a computer, underneath things like word processors and
spreadsheets). UNIX is designed to be used by many people at the same time (it is multi-user) and has TCP/IP
built-in. It is the most common operating system for servers on the Internet.

Unprintable area --- URL
|
|
Unprintable area ---
The area, usually around the extreme edges of the paper, in which the printer is incapable of printing.
For example, a laser printer cannot print in the 1/4" at the left and right edges of the paper. It is important
to know the unprintable area, since graphics or text you place in this area will be cut off when printed.
Upgrade
fever --- The almost uncontrollable, compulsive
urge to upgrade hardware and/or software, with little or no consideration extended to a real need or want.
Upholstry --- Useless graphics on a webpage,
that serve no purpose other than meaningless decoration, esp. if they distract from the
purpose of the page.
Upload --- The process of transferring information
from your computer to another computer through the Internet. Every time you send e-mail to someone you are uploading
it.
URL --- (Uniform
Resource Locator) -- The standard way to give the address of any resource on the Internet that is part of the World
Wide Web (WWW). A URL looks like this:
http://www.matisse.net/seminars.html
or telnet://well.sf.ca.us
or news:new.newusers.questions
etc.
The most common way to use a URL is to enter into a WWW browser program, such as Netscape, or Lynx.

Usenet --- User Session
|
|
Usenet
--- Often referred to as simply "newsgroups" is a distributed
bulletin board system supported mainly by UNIX machines. Originally implemented in 1979--1980 by Steve Bellovin,
Jim Ellis, Tom Truscott, and Steve Daniel at Duke University, it has swiftly grown to become international in scope
and is now probably the largest decentralized information utility in existence. As of early 1993, it hosted well
over 1200 newsgroups and an average of 40 megabytes (the equivalent of several thousand paper pages) of new technical
articles, news, discussion, chatter, and flamage every day.
Usenet groups can be "unmoderated" (anyone can post) or "moderated" (submissions are
automatically directed to a moderator, who edits or filters and then posts the results). Some newsgroups have parallel
mailing lists for Internet people with no netnews access, with postings to the group automatically propagated to
the list and vice versa. Some moderated groups (especially those which are actually gatewayed Internet mailing
lists) are distributed as `digests', with groups of postings periodically collected into a single large posting
with an index.
Newsgroups Available - A pretty good attempt at organizing and listing the ever growing newsgroups.
Newslist 1.9 - A python program for UNIX machines which automatically constructs an HTML page listing all the newsgroups
available by your Internet Access Provider.
User Address --- The domain name or IP address
for the remote user.
User Agent --- The fields in an extended
Web server log file indicating the browser and the platform used by a visitor.
User ID --- This is the unique identifier
(like your logon name) that you use to identify yourself on a computer. You probably typed your User ID (and password)
when you logged onto the Internet today.
User Session --- A session of activity (all
hits) for one visitor to a Web site. A unique user is determined by the IP address or domain name. By default,
a user session is terminated when a user falls inactive for more than 30 minutes.

UUCP --- UUENCODE
- UUDECODE

UUCP
--- UNIX to UNIX copy - A tool for transferring
files, sending mail, and executing remote commands that was invented in 1978 at AT&T Bell Laboratories by Mike
Lesk.
UUEE
--- UNIX to UNIX Encode - A tool for transferring
files through e-mail.
UUENCODE --- (Unix to Unix Encoding) -- A
method for converting files from Binary to ASCII (text) so that
they can be sent across the Internet via e-mail.
See Also: Binhex , MIME
UUENCODE - UUDECODE --- A method
for converting binary information into ascii. It can be used for posting to Usenet and or e-mailing with non MIME
compliant mail readers.
