A Cray SuperComputer Comes To The University Of Toronto
.... in one clock cycle. This power is measured in
Millions of Floating Point Operations Per Second (MFLOPS) - which is to
say the rate at which floating-point operations can be performed. The Cray
MFLOPS vary as it does many activities, but a rate of up to 210 MFLOPS
(per CPU) can be achieved.
The second '2' in the X-MP/22 title refers to the two million 64-bit
words (16Mb) of shared central memory. This can be expanded to four
million words in the future if the need arises. But it doesn't stop there!
The Cray can pipe information back and forth between the CPU memory and
the Input/Output Subsystem (IOS). The IOS then takes .....

Object-Oriented Database Management Systems
.... or under development today share a
set of fundamental object-oriented concepts. Therefore the implementation
issues in OODBMSs that arise due to these concepts are universal. The
third characteristic is that of experimental activity. Plenty of
prototypes have been implemented and some !
of them became commercial products. There is really a need for
applications to handle very complex data and that is why the interest of
people in building such systems is so strong.
Although there is no consensus on what an OODBMS is and which are the
features that differentiate it from other systems, there has been a lot of
effort for .....

A Look At Public Key Encryption

opposite sides of the spectrum, but both have their similarities and their
differences.
The major difference complexity, the government pays mathematicians to
research complex algorithms by which to encode the messages, like the
system used by Captain Video but these algorithms are complex enough that
if you tried to crack them it would take you decades with even the most
powerful computer today. This complex mathematical code is what makes the
text secure to anyone who tries to crack it. Some similarities we can find
in these two examples are their u .....

Even From It's Humble Beginnings, The Internet Has Always Been A Battlefield Between Phreaks And Administrators
.... for years. The Internet is just a new fad ("The More I Learn"
A1). The Internet originally began as DARPANET, a government-created
network, which was designed for defense communications. The Net structure
is such that it could survive a nuclear war ("Internet History"). The
creation of the Net can not be blamed for the existence of hackers though,
hackers are older than the Net itself, but the Net is the largest 'hacker
haven' today (Spencer, "Hacking McDonalds" 6).
The growth of the Net since its creation has been nothing less than
astounding. In the 25-plus years since its creation, the Net now has over
thirty million u .....

Classification Analysis
.... is just that they
never realize it is also a form of output.
As opposed to 'output', 'input' consists of components that take in
information from the users themselves so that the computer will know the
tasks it is supposed to perform and accomplish. The keyboard is classified
as a form of input because this is where the users enter commands and text.
There are many other forms of input as well. Nonetheless, many people just
don't realize them, or are too lazy to classify them. For instance, the
mouse belongs to input, since it provides a floating pointer on the screen
so that the users can access commands faster and easie .....

As A Technology, It Is Called Multimedia
.... thing about the multimedia boom, is that so many
moguls are spending such vast sums to develop digital technologies, for the
delivering of programs and services which are still largely hypothetical.
So what is behind such grand prophecies? Primarily, two technological
advances known as digitization (including digital compression), and fibre
optics.
Both are indispensable to the high-speed networks that will deliver dynamic
new services to homes and offices. Digitization means translating
information, either video, audio, or text, into ones and zeros, which make
it easier to send, store, and manipulate. Compression squee .....

Internet Regulation: Policing Cyberspace
.... from its agencies.
This material is not lawfully available through the mail or over the
telephone, there is no valid reason these perverts should be allowed
unimpeded on the Internet. Since our initiative, the industry has
commendably advanced some blocking devices, but they are not a substitute
for well-reasoned law.4 Because the Internet has become one of the biggest
sources of information in this world, legislative safeguards are
imperative.
The government gives citizens the privilege of using the Internet, but it
has never given them the right to use it.
They seem to rationalize that the framers of the constitu .....

Government Censorship Would Damage The Atmosphere Of The Freedom To Express Ideas On The Internet; Therefore, Government Should Not
.... body of
legislation, it is important to explore the controversy, and the current
problems involved with the Net as it exists must be introduced.
1. The problem that concerns most people is offensive materials such as
pornography.
2. Another crucial internet crime is the stealing of credit card numbers.
III. One reaction to this inapplicability has been the "Censor the Net"
approach (the censorship bill), we are now to compare its advantages and
disadvantages.
1. First, the meaning of "Censoring the Net" must be explained.
2. However, many experts have pointed out that government censorship is not
possible.
1. First, it is no .....

The Vast Cyber-frontier Is Being Threatend With Censorship From The Government
.... who might upload James
Joyce's Ulysses could be placed in jail for two years and have up to a
$250,000 fine.3 Representatives of on-line services industries were
concerned about the bill, and feared they could be held criminally
responsible for Internet conversations.4
"We face a unique disturbing and urgent circumstance, because it is
children who are the computer experts in our nations families," remarked a
concerned Rep. Senator of India Dan Coats.5 Although in reality,
censorship would do little to stop the pornography problems. The bill is a
nation legislation trying to control a international network, which is

Semiconductors : The Silicon Chip
.... to the group IV in the periodic
table. It is a grey brittle material with a diamond cubic structure.
Silicon is conventionally doped with Phosphorus, Arsenic and Antimony and
Boron, Aluminum, and Gallium acceptors. The energy gap of silicon is 1.1
eV. This value permits the operation of silicon semiconductors devices at
higher temperatures than germanium.
Now I will give you some brief history of the evolution of electronics
which will help you understand more about semiconductors and the silicon
chip. In the early 1900's before integrated circuits and silicon chips
were invented, computers and radios were made wit .....

Economic Consequences Of Software Crime

human resources in regards to software distribution and licensing.
Information can qualify to be property in two ways; patent law and
copyright laws which are creations of federal statutes, which are subject
to Constitutional authority. In order for the government to prosecute the
unauthorized copying of computerized information as theft, it must first
rely on other theories of information-as-property. Trade secret laws are
created by provincial law, and most jurisdictions have laws that
criminalize the violations of a trade-s .....
