The Telephone System
.... metal disk. This plastic disk
is electrically charged, and creates an electric field. The sound waves from
the caller's voice cause the plastic disk to vibrate, changing the distance
between the disks, thus changing the intensity of the electric field. These
variations are translated into an electric current which travels across the
telephone lines. The receiver of a telephone is composed of a flat ring of
magnetic material. Underneath this magnetic ring is a coil of wire where the
electric current flows. Here, the current and magnetic field from the magnet
cause a diaphragm between the two to vibrate, and replicate the .....

.... to handle any of the new software two years from now. Owners must
not only keep up with the new trends but must also be well aware of what their
own system can sustain so that they do not overload it and cause it to crash.
This article focuses on interactive video, which is a relatively new field in
the gaming industry. The games that have been on the market have not lived up
to the bombardment of advertising gamers have been subjected to. The video
itself is often choppy and blurry, it rarely enhances the plot of the game, and
has yet to be truely interactive. This is because it is not part of a movies
nature to mingle with t .....

Truth And Lies About The Computer Virus
.... truth
about viruses. "Antivirus firms tend to count even the most insignificant
variations of viruses for advertising purposes. When the Marijuana virus first
appeared, for example, it contained the word "legalise," but a miscreant later
modified it to read "legalize." Any program which detects the original virus can
detect the version with one letter changed -- but antivirus companies often
count them as "two" viruses. These obscure differentiations quickly add up."
http://www.kumite.com/myths/myth005.htm Incidentally the Marijuana virus is also
called the "Stoned" virus there by making it yet another on the list of viruses

The V-Chip

Services)program ratings, compare these ratings to viewer standards, and can be
programmed to take a variety of actions, including complete blanking of
programs." Is one definition of the V-chip from Al Marquis of Zilog Technology.
The FCC or Capitol Hill has not set any standards for V-chip technology; this
has allowed many different companies to construct chips that are similar yet not
exact or possibly not compatible. Each chip has advantages and disadvantages for
the rating's system, soon to be developed. For example, some units use onscreen
programming such as VCR's and the Zilog produ .....

Video Cards
.... three dimensional graphics,
but why the video card in the past could only process low resolution two
dimensional graphics. The explanation will be based on some recently developed
video cards such like Matrox Millenium. This paper will also discuss how the 3D
graphic displays on a 2D monitor. Lastly, the video card, Matrox Millennium,
will also be discussed.
Basic principles
In order to understand the recent development of the video card, let's
take a look on how a video card works.
The video card is a circuit, which is responsible for processing the
special video data from the central processing unit (CPU) into a format .....

Video Games: The High Tech Threat To Our Younger Generation
.... film industry (110).
He continues to point out that two Japan based conglomerate have put about 64
million videogame machines in US households in total. In addition to that they
also produced and licenced for all their softwares for their machines (110).
Palmery estimates to produce and market a ful featured videogame it would costs
up to $10 million (102). Because of the cost producers attempt to make a return
on their investments and earn as much profits as they can. To achieve their
goals, they feature more blood, gore and human dismemberment in their games to
appeal to the younger generation because violence sells. A .....

Overview Of Video On Demand Systems
.... for explosive growth. The technology for this necessary and much-
anticipated business tool has been in development for years. By the turn of the
century, teleconferences that include any combination of video, audio, data, and
graphics will be standard business practice.
Compliance with teleconferencing standards will create compatible solutions from
competing manufacturers, feeding the market with a variety of products that work
together as smoothly as standard telephone products do today. Specifically, with
the adoption of International Telecommunications Union (ITU) recommendations
T.120, H.320 and H261, multimedia teleconf .....

Virtual Reality
.... calculations required by a virtual reality based machine.
However, as apparent in recent years, technology is advancing at an extreme rate.
This is another reason why society's hopes for virtual reality should and have
remained unwaivered.
In Orenstein's story, she gives the perspective of the average citizen who
is obviously uncertain about the uses and/or affects that virtual reality will
have upon society. The show she attended was quick to point out the
practicality of virtual reality however, it still left much to be desired. It
seems that Orenstein was disgruntled when she came to an exhibit and the topic
of cyber- .....

Virtual Reality - What It Is And How It Works
.... is done with several computer-user interfaces used to simulate the senses.
Among these, are stereoscopic glasses to make the simulated world look real, a
3D auditory display to give depth to sound, sensor lined gloves to simulate
tactile feedback, and head-trackers to follow the orientation of the head.
Since the technology is fairly young, these interfaces have not been perfected,
making for a somewhat cartoonish simulated reality.
Stereoscopic vision is probably the most important feature of VR because in
real life, people rely mainly on vision to get places and do things. The eyes
are approximately 6.5 centimeters .....

Virtual Reality
.... flight simulators.
Most have to travel hundreds of miles to take advantage of these amazing
simulators. Flight simulators are much better than an airplane for the simple
reason that in a simulator the learning environment is much safer. Students
are able to avoid the overriding need to keep the airplane flying and out of
harm's way. In a simulator a student is constantly busy, practicing what he is
supposed to be learning, and once he's flown a given maneuver, he is able to go
back and do it over again, without wasting time or fuel.
Years ago doctors used X-rays to see the insides of humans. X-ray's
were most helpful i .....

Are "Good" Computer Viruses Still A Bad Idea?
.... between those
supporting the idea of a "beneficial virus" and those opposing it, is that the
two sides are assuming a different definition of what a computer virus is.
1. What Is a Computer Virus?
The general public usually associates the term "computer virus" with a small,
nasty program, which aims to destroy the information on their machines. As usual,
the general public's understanding of the term is incorrect. There are many
kinds of destructive or otherwise malicious computer programs and computer
viruses are only one of them. Such programs include backdoors, logic bombs,
trojan horses and so on [Bontchev94]. Furthermore, ma .....

Computer Viruses
.... a
program that watches for typical things viruses do, halts them, and warns the
computer operator.
"Put a kid with the chicken pox together with a bunch of healthy kids and not
all of them will get sick." But that is not the case with computer viruses.
You see when a computer virus passes on a virus it never fails unless the
computer is protected with a vaccine. A typical computer virus spreads faster
than the chicken pox too. Now as I said before when a computer virus attempts
to infect another computer the attack is not always successful. However that
does not mean the infected computer stops trying. An infected computer .....
