The Future Of Fiber Optics On The Internet
... to another in the form or light, guided through thin fibers of glass or plastic. Fiber Optics can represent information from voice, date, video and images, which allows for use with telephones, computers, and televisions. A strand of glass is thinner than a human hair, yet inch by inch is stronger than steel.
The future of fiber optics is very promising due to the simple fact of how much information they can carry. Two single fiber optics lines carry the equivalent of 24,000 telephone calls at one time. With the introduction of fiber optics into our daily lives, it will greatly improve the quality and speed of ...
Computer Fraud And Crimes
... takes many man hours
and a lot of money for site licenses. Many server programs are coming equipped
with a program called "netlog." This is a program that monitors the computer use
of the employees in a company on the network. The program monitors memory and
file usage. A qualified system administrator should be able to tell by the
amounts of memory being used and the file usage if something is going on that
should not be. If a virus is found, system administrators can pinpoint the user
who put the virus into the network and investigate whether or not there was any

Computers Not The Greatest Invention Of The 20 Th Century
... on our lives and promises they hold for the future, it is important to understand their evolution.
The abacus, which emerged about 5,000 years ago in Asia Minor and is still in use today, may be considered the first computer. This device allows users to make computations using a system of sliding beads arranged on a rack. Early merchants used the abacus to keep trading transactions. But as the use of paper and pencil spread, particularly in Europe, the abacus lost its importance. It took nearly 12 centuries, however, for the next significant advance in computing devices to emerge. In 1642, Blaise Pascal, the ...
... blocks of time with the discovery of certain raw materials
that humans utilized. The Bronze Age and the Iron Age were two periods in human
history that proved through the discovery of artifacts that humans learned to
harness these raw materials ingeniously. The Industrial Revolution of the late
nineteenth century brought the discoveries of the Bronze and Iron Ages to new
heights, and the advent of the locomotive, automobiles, cargo ships and
airplanes were the most evident by-products of such raw materials. Use of these
by-products from the earth's raw materials dramatically changed the world of
business and tr ...
The Linux Operating System
... and developers may charge money for it as long as the source code remains available. Linux may be used for a wide variety of purposes including networking, software development, and as an end-user platform. Linux is often considered an excellent, low-cost alternative to other more expensive operating systems.
Due to the very nature of Linux's functionality and availability, it has become quite popular worldwide and a vast number of software programmers have taken Linux's source code and adapted it to meet their individual needs. At this time, there are dozens of ongoing projects for Linux to different hardware c ...
Computer In The Classroom
... and how will we prevent the computers from overbearing our voices? If there is more than one computer, how shall we network them? Possibly the last and most important question is how we make it available and easy for everyone who wants to use it?
Traditionally, each student sitting at a computer would have a 14" or 15" conventional monitor sitting on the desk, taking up a good 50% of the workspace. These monitors are usually greater than a .3 dot pitch or worse and some with only a 33 mHz refresh rate. According to Van Horn, a professor at Augsburg, in his essay titled Electronic classrooms: design and use, t ...
... A tremendous
amount of energy is required to produce transportation equipment such as
automobiles, buses trains, and subways. If telecommuting is promoted, there
will be less use of this equipment and less energy will be required for
production, maintenance, and repair of this equipment. Fuel resources needed to
operate this equipment will be reduced. The building and repair of highways and
maintenance requires a large consumption of energy, not only in the operation of
the highway construction and repair equipment, but also in the manufacture and
transportation of the required materials. An increase in the perc ...
The Electronic Computer
... and communicating ideas, such as the technology of writing and printing. In the past ten years, however, a powerful, general-purpose mind tool, , has become widely available. In almost any shopping mall we can now buy a machine that will not only do our arithmetic. In addition, this machine helps us think, write, draw, play music, learn, keep records and retrieve information. It is that we are using every day.
The idea of an automatic computing machine can be traced back to the mid-nineteenth century. But it was only in the 1904s, when electronics was applied to the task of automatic computing, that fast, reliable ...
Digital Block For A Function Generator
... be found at the end of this report.
User inputs are also digitally processed in this function generator and sent out as digital signals to other parts of this function generator namely the amplifier module. Also a filter selector circuit is built in after the digital block. The user inputs controlling frequency and symmetry are also built into this control block.
Therefore it is clear that the digital block can be divided into 4 distinct blocks, each with its own functionality. These blocks are the control module, counter module, filter control module and 8-bit D/A. The D/A chosen is the DAC0801LCN. Itís specificati ...
