In the US, in 1993, Marc Andreesen, an
undergraduate student at the University of
Illinois at Urbana-Champaigne, and his team,
while working on a National Center for
Supercomputing Applications (NCSA),
developed another graphic user interface
browser they named Mosaic.
The graphic user interface (GUI) popularized the
user and fueled the growth of the world wide
web to bring it to the point where it is today.

Ethical Problems in Computing
The Emergence of Computer Crimes – The known history of computer crimes is not as old as computing is.
– One can perhaps say that the history of computer crimes started with the
invention of the computer virus.
– The term virus is derived from a Latin word virus which means poison. For
generations, even before the birth of modern medicine, the term had
remained mostly in medical circles, meaning a foreign agent injecting itself in
a living body, feeding on it to grow and multiply.
– As it reproduces itself in the new environment, it spreads throughout the
victim's body slowly disabling the body’s natural resistance to foreign objects,
weakening the body’s ability to perform needed life functions and eventually
causing serious, sometimes fatal effects to the body.
– A computer virus, defined as a self-propagating computer program designed
to alter or destroy a computer system resource, follows almost the same
pattern but instead of using the living body, it uses software to attach itself,
grow, reproduce and spread in the new environment.
– As it spreads in the new environment, it attacks major system resources that
include the surrogate software itself, data, and sometimes hardware
weakening the capacity of these resources to perform the needed functions
and eventually bringing the system down.
– – The word virus was first assigned a non-biological meaning in
the 1972 science fiction stories about the G.O.D. machine, that
were compiled in a book When Harly was One by David Gerrod
( Ballantine Books, First Edition, New York, NY, 1972). The term
was first used to describe a piece of unwanted computer code.
– Later association of the term with a real world computer program
was done by Fred Cohen, then a graduate student at the
University of Southern California.
– Cohen first presented his ideas to a graduate seminar class in
information security in 1983. His seminar advisor, Len Adleman,
was the first to assign the term "virus" to Cohen's concept.
– As part of these experiments, Cohen wrote five programs,
actually viruses, to run on a VAX 11/750 running Unix, not to
alter or destroy any computer resources but for class
demonstration. During the demonstration, each virus obtained
full control of the system within an hour .
– From that simple beginning, computer viruses, and hence
computer crimes have been...
