The Internet
... foremost military think tank, were trying to figure out the important strategic problem of how could US authorities talk to each other in the aftermath of a nuclear attack? Communication networks of that time were chained point-to-point, with each place on the network dependent on the link before it. If one point in the network were blown up, the whole network would become useless. Paul Baran, one of the Rand thinkers on the project, conceived the idea for a new kind of communications network that wasn't organized point-to-point, but instead was set up more like a fishnet. He believed this structure could allow information to find its own path through the netwo ...

Semiconductors : The Silicon Chip
... or amorphous. Elemental semiconductors
are simple-element semiconductor materials such as silicon or germanium.
Silicon is the most common semiconductor material used today. It is
used for diodes, transistors, integrated circuits, memories, infrared
detection and lenses, light-emitting diodes (LED), photosensors, strain
gages, solar cells, charge transfer devices, radiation detectors and a
variety of other devices. Silicon belongs 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 ...

... reflected from it. Your two eyes
each see a slightly different view of the apple. These different views
tell you about the apple's depth -its form and where it sits in relation to
other objects. Your brain processes this information so that you see the apple,
and the rest of the world, in 3-D. You can look around objects, too -if the
apple is blocking the view of an orange behind it, you can just move your
head to one side. The apple seems to "move" out of the way so you can
see the orange or even the back of the apple. If that seems a bit
obvious, just try looking behind something in a regular photograph!
You can't ...

... this area of interest? From the first day that I
started my first computer, I have grasped the concepts quickly and with ease.
But the computer as well as I will never stop growing. I have introduced myself
to all topics of word processing to surfing the web. After reviewing a number
of resources, I have noticed a relatively high demand for technologically
integrated hardware and software positions available with companies that wish to
compete with the demand for “networking”. (“Computer Scientists” 95) This leads
me to believe that future employment prospects will be high and of high quality
pay within the next eight to ten years. The past, present, and futur ...

The Introduction Of Computers In Education
... information. These students learn how to use the computer at an early stage and can utilize these skills as they enter college.
The in home computer called the personal computer has now become a part of the home appliance and entertainment center. They are now in about every household across America. Students are now doing the majority of their research in the comforts of home with less distraction. The software for PCs is extensive and the students can obtain all the information he/she needs for an assignment. The time that was spent running to the library has been cut by about ninety percent. This is due to the new and ever improving software that is produced f ...

Windows 95 Or NT
... so each one of these operating
systems has there good side and there bad side.
Windows NT 3.51 was originally created for business use, but has ended
up being more widely available for the average PC user in ones home. Windows 95
was developed for the sole purpose as an alternative to Windows NT. But has
ended up in the work place more then the home. Windows 95 carries an average
price of ninety-five dollars in stores. Which makes it an expensive system
worth the money. On the other hand Windows NT 3.51 carries a price tag of
three-hundred and forty nine dollars. Making this software very expensive but
also worth every penny.
Windows 95 is much easier t ...

Computer Crimes
... of the "hunt" at pushes them to such great lengths. Many
employees that work in large corporations feel that they don't get paid as much
as they should. Therefore if they have high security clearance they are able to
capitalize from that by selling the data they have access to on the black-market.
Whether it be Ford Motor companies plan for the 1999 F-150 or spec sheets for
the military's new bomber it happens everyday. Too by left is a drawing that
illustrates the method that most Hackers use to take over your computer. Ever
since the dial-up connection was invented anyone with a modem had the ability to
wreck any one of thousands of computers.

The History And Future Of Computers
... The primitive start of the computer came about around 4000 BC; with the
invention of the abacus, by the Chinese. It was a rack with beads strung on
wires that could be moved to make calculations. The first digital computer is
usually accredited to Blaise Pascal. In 1642 he made the device to aid his
father, who was a tax collector. In 1694 Gottfried Leibniz improved the machine
so that with the rearrangement of a few 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 versati ...

The Information Super Highway
... click of the mouse. The Internet is difficult to limit because the devices used today are not capable of monitoring such a vast new medium.
Any new medium must go through investigation and must be explored to see the full potential and how it affects society. In the 1940’s radio emerged as a strong medium, allowing thousands to hear news, entertainment, and even propaganda. Radio was new and was therefore forced to restrict its use of certain ideas and vocabulary. Years went by and a new form of media emerged: the device television, which was used to see pictures. Another new medium of communication except now with sight too. Television too was forced to res ...
