This refers to the notion of having sex while being online. No, you can't really "do it" over the net, just as you can't with phone sex, but users can visit chat rooms or IM with each other as a form of stimulation.
A form of punishment given to children, tweens, or adolescents by their parents due to excessive online usage, visiting websites that are not allowed, sneaking online after hours, cyberbullying, or any other kind of online misbehavior. It is a modern form of discipline in a technological era where sending kids to their room isn't necessarily relevant because they can often text or access the Internet. The purpose of grounding is to teach a lesson by depriving kids of their social connections, which now includes technology.
A young person who is "digitally grounded" may be forbidden to use electronic devices (either completely or partially), forbidden to access Facebook or other sites (for a week or two), forbidden to use a cell
phone (for social use), and may also include no TV or video games for a specified amount of time.�
Historical perspective: In 2010, the Pew Internet & American Life Project published a report that captured part of the "digital grounding" trend. It said 62% of parents said they had taken away a cell phone as punishment.
Creating queries based on user data, environment variables, and previously returned query results, dynamic SQL can also execute multiple queries and send them to multiple databases from a single browser request. This increases processing efficiency.
Synonymous with a crawler, this is a program that searches the Internet and attempts to locate new, publicly accessible resources, such as WWW documents, files available in public FTP archives, and Gopher documents.
Also called wanderers or bots, spiders contribute their discoveries to a database that Internet users can search by using a search engine. Spider technology is necessary because the rate at which people are creating new Internet documents greatly exceeds any manual indexing capacity (although search directories prefer the manual approach).
"Cyberstalking" refers to contacting a person online persistently, especially out of obsession or derangement. For example, if a man sends a woman threatening e-mails or repeatedly contacts her via her social networking page, he could be charged with a felony.
A "Google stalker" is when someone locates you by doing a search on Google and then incessantly emails you. They are said to be Google stalking (or cyberstalking) you.
A Web site that provides links to information organized into a categorical, alphabetical hierarchy. Yahoo! is the most popular online search directory.
Unlike a search engine, which uses bots to sort its information and relies soley on Internet technology to operate, a search directory is human-organized, meaning that real people actually edit the links and classify them into the directory. The result of this distinction is easily apparent when doing an online search: instead of a search engine spit-out of hundreds of thousands of results (many of which are irrelevant), a directory comes back with links that are more accurate and better organized. If you don't know the actual URL of a Web site you want to see, try searching Yahoo! first; if you still can't find any interesting, related information, then go to a search engine (and take time to learn how to use the "advanced search" feature).
An electronic library provides online access to public catalogs, CD-ROM indexes, online databases, audio files, and video conferencing tools. As with public libraries, you'll need a certain amount of mastery in order to find what you're looking for in an electronic library.
The ability to work collaboratively on a document, where everyone may add or edit text. A "wiki" is a type of Web site or tool for doing jointly authored writing using the Internet. The idea is that this kind of "open editing" allows for easy interaction between users and/or groups and is effective in collaborative authoring.
In the industry, "wiki" is said to be "the simplest online database that could possibly work." It is a server software and its main advantages are ease-of-use, global access, and low cost. Like blogging, it allows anyone the ability to publish their writing directly on the Web, however, this kind of free expression comes with a caveat: DBEYR.
The term wiki originates from the Hawaiian word for "fast" or "quick" and was coined in 1995 by Ward Cunningham. In March 2007, the
word wiki became a newly recognized English word.
Historical perspective: In 2007, here were the Top 10 Wikis:
This technology allows a user to access the Internet via a satellite that orbits the earth. A satellite is placed at a static point above the earth's surface. From a fixed position (also referred to as GEOS), the statellite is able to maintain a reliable connection to the antennas on the earth. It orbits the earth at the exact speed of the earth's rotation. Because of the enormous distances signals must travel-from earth, up to the satellite and back down again-IoS is slightly slower than high-speed connections over copper or fiber-optic cables.
In remote regions of the world, Internet over Satellite is a viable option because installing the cable backbone necessary for Internet connectivity is not economically feasible or physically possible. This technology represents a big step toward building a "global village," and it's an example of how wireless technology can connect parts of the world that previously had little or no technology, let alone access.
UWB uses a huge swath of radio frequencies to transmit minute pulses of information allowing the signal to go through objects. The applications include radar imaging of buried objects (popular with the Pentagon).
A set of moral principles common to the first-generationhacker community. According to hacker ethic, all technical information should, in principle, be freely available to all. However, destroying, altering, or moving data in a way that could cause injury or expense to others is always unethical.
Google finds over 250,000 web pages that refer to "nigritude ultramarine", a phrase that translates roughly into "dark blue." This strange phrase appeared in many blogs and Web sites in 2004 as the result of a search engine marketing challenge.
One of the two most common types of image formats used on the World Wide Web (the other being GIF). The shorter extension, JPG (without the E), is usually used in association with PCplatform files.
A standardized image compression mechanism, JPG is named after the original name of the committee that wrote the standard, the "Joint Photographic Experts Group." JPG is designed for compressing either full-color or gray-scale images of natural, real-world scenes. It works well on photographs, naturalistic artwork, and similar material; not so well on lettering, simple cartoons, or line drawings. JPG handles only still images, but there is a related standard called MPEG for motion pictures. JPG is "lossy," meaning that the decompressed image isn't quite as sharp as the one you started with. (There are "lossless" image compression algorithms, but JPG achieves much greater compression than is possible with lossless methods.) JPG is designed to exploit known limitations of the human eye, notably the fact that small color changes are perceived less accurately than small changes in brightness. Thus, JPG is intended for compressing images that will be looked at by humans. If you plan to machine-analyze your images, the small errors introduced by JPG may be a problem, even if they are invisible to the eye.
On the Web, there are image archives set up for Web designers to acquire graphics easily. These sites usually display thumbnail versions of images that may be GIFs or JPGs. Clicking on these thumbnails will usually link you to the larger, higher-resolution version of the same image.
An alternative to Wi-Fi, it is a protocol for wirelessnetworking (at 1.6 Mbps and increasing to 10 Mbps). HomeRF is a leading RF technology backed by corporations such as Compaq, Motorola, National Semiconductor, Proxim, and Siemens. Like Wi-Fi (also known as 802.11b), HomeRF operates on the 2.4 GHz spectrum but differs in that its signals hop among different frequencies (or bands) within the radio frequency spectrum.
Another name for the CD-DA audio
CD format introduced by Sony and
Philips, the Red Book standard defines
the number of tracks on the disc that
contain digital audio data and the error
correction routines that save sound
from minor data loss. The format allows
for a total of 74 minutes of digital sound
to be transferred at a rate of 150
kilobytes per second (K/sec).
