Computer Pornography
.... on the Internet(Wallace: 1). The CDA describes indecent speech as
anything "depicting or describing sexual or excretory acts or organs in
patently offensive fashion under contemporary community standards."
First take the word "indecent". This word is used because of its vague
definition. Not only does this word ban sexually explicit materials, it also
bans sexually explicit words too. If this were applied to the real world some
of the greatest novels would be taken off the shelf. For example there is the
great lesbian novel The Well of Loneliness by Radcliffe Hall. In that book
there is a line t hat states "And that .....

.... same drum as the potential
victim but follows and unanticipated path."(Blumenthal, 1:2) There is no actual
profile of a computer criminal because they range from young teens to elders,
from black to white, from short to tall.
Definitions of computer crime has changed over the years as the users
and misusers of computers have expanded into new areas. "When computers were
first introduced into businesses, computer crime was defined simply as a form of
white-collar crime committed inside a computer system."(2600:Summer 92,p.13)
Some new terms have been added to the computer criminal vocabulary.

The History And Future Of Computers
.... parts it could be used to multiply. The
next logical advance came from Thomas of Colmar in 1890, who produced a machine
that could perform all of the four basic operations, addition, subtraction,
multiplication and division. With the added versatility this device was in
operation up until the First World War.
Thomas of Colmar made the common calculator, but the real start of
computers as they are known today comes from Charles Babbage. Babbage designed
a machine that he called a Difference Engine. It was designed to make many long
calculations automatically and print out the results. A working model was built
in 1822 a .....

Computer Viruses
.... damage happens when all you have to do is get rid of the virus. There
may be some audio or visual effect; often there is no effect at all.
Minor damage occurs when you have to replace some or all of your executable
files from clean backups, or by re-installing. Remember to run FindVirus again
afterwards.
Moderate damage is done when a virus trashes the hard disk, scrambles the FAT,
or low-level formats the drive. This is recoverable from your last backup. If
you take backups every day you lose, on average, half a day's work.
Major damage is done by a virus that gradually corrupts data files, so that you
are unaware of what is h .....

disks can be used, and is loaded into memory each time the computer is booted by
one of these disks.
DON'T DESPAIR!
Despite all of what has just been said, viruses are controllable. Their is
software called Virus Protection Software. A couples of programs that have been
proven to work are F-PROT and McAfee's Virus Scan. These programs scan the
computer's memory and the files contained on the hard disk each time the program
is executed. These programs also resided on the computer's memory. These
programs will .....

a glitch in The Rome Air Force Base's system. The telecommunications giant
of the west Southwestern Bell had a problem with a hacker named
Christopher Schanot that cost them around 100,000 dollars. According to
the CSI \ FBI Computer Crime and Security Survey, 246 organizations
reported over 100,000,000 dollars in financial loses due to security
breaches in 1997 (Intranet Security xvii). The survey, keep in mind,

Computer Viruses: Past, Present And Future
.... files) or to the boot sector of a disk. When an infected file is
activated - or executed - or when the computer is started from an infected disk,
the virus itself is also executed. Often, it lurks in computer memory, waiting
to infect the next program that is activated, or the next disk that is accessed.
What makes viruses dangerous is their ability to perform an event. While some
events are harmless (e.g. displaying a message on a certain date) and others
annoying (e.g., slowing performance or altering the screen display), some
viruses can be catastrophic by damaging files, destroying data and crashing
systems.

Airplanes
.... with two sets are called biplanes.
To help fly the airplane, the wings have two types of control surfaces
attached to the rear, or trailing, edges. They are referred to as ailerons
and flaps. Ailerons extend from about the midpoint of each wing outward to
the tip. They move in opposite directions - when one aileron goes up, the
other goes down. Flaps extend outward from the fuselage to the midpoint of
each wing. They always move in the same direction. If one flap is down,
the other one is also down.
The empennage consists of the vertical stabilizer, or fin, and the
horizontal stabilizer. These two surfaces .....

they or their contents are damaged, as when terrorists attack computer centres
with explosives or gasoline, or when a "computer virus" a program capable of

Personal Computer
A personal computer is a computer that is based on a microprocessor, a small
semiconductor chip that performs the operations of a c.p.u.
Personal computers are single-user machines, whereas larger computers generally
have multiple users. Personal computers have many uses such as: Word processing,

Computer Crime
.... most kinds of crime, including fraud, theft,
larceny, embezzlement, burglary, sabotage, espionage, murder, and forgery, since
the first cases were reported in 1958. One study of 1,500 computer crimes
established that most of them were committed by trusted computer users within
businesses; persons with the requisite skills, knowledge, access, and resources.
Much of known computer crime has consisted of entering false data into computers,
which is simpler and safer than the complex process of writing a program to
change data already in the computer. With the advent of personal computers to
manipulate information and access compute .....

Data Storage Devices
.... data storage medium. To
read data, a tape drive must wind through the spool of tape to the exact
location of the desired information. To write, the tape drive encodes data
sequentially on the tape. Because tape drives cannot randomly access or
write data like disk drives, and are thus much slower, they have been
replaced as the primary storage device with the hard drive. The hard drive
is composed of thin layers of rigid magnetic platters stacked on top of one
another like records in a jukebox, and the heads that read and write data
to the spinning platters resemble the arm of a record player. Floppy
disks are another common .....
