in overall performance. Many people don't know this and that is how computer corporations have
cheated people out of their money for so many years by selling them cheep systems with high
megahertz numbers for the processors in them. This is one reason for the success of the computer
industry. When people find out that they have been cheated, they will try to learn more about the
product and probably end up spending more money next time. Either way the computer companies

for any young enthusiast and this tren is looking just as bright in the new millenium. Computer
science and technology has much to offer in anyone of its many career paths. Whether working with

Essay about The History of Computers
The first ever computer was invented in the 1820s by Charlse Babbage. However the first
electronic digital computer were developed between 1940 and 1945 in the United States and in the
United Kingdom. They were gigantic, originally the size of a large room, and also need to be
supply a large amount of power source which is equivalent as several hundred modern personal
computers. The history of computer hardware covers the developments from simple devices to aid
calculation, to mechanical calculators, punched card data processing and on to modern stored
program computers. The tools or mechanical tool used to help in calculation are called calculators
while the machine operator that help in calculations is called computer. At first the...show more

UNIVAC 1 was created to process data like Herman Hollerith's tabulator over 50 years before,
however UNIVAC 1 was then manufactured for other users and become the world's first large scale
commercial computer. The key period of the evolution of modern electronic computer is in between
the late 1930s and the early 1950s. Not all of them were invented by the mathematician or physician.
Among those machines were pioneering computers put together by english academics notably
Manchester/Ferrenti Mark 1, built at Manchester University by Frederic Williams and Thomas
Kilburn. And the EDSAC, Electronic Delay Storage Automatic Calculator built by Maurice Wilkes
at Cambridge University. The microelectronic revolution started when they were using the vacuum
tubes it consume a lot of power supply. As a comparison the ENIAC used about 2000 times as
much electricity as the modern laptop. Not just that, the modern term for a problem that holds up a
computer program is a "bug". Popular legend has it that this word entered the vocabulary of
computer programmers sometimes in the 1950s when moths, attracted by the glowing lights of
vacuum tubes, flew inside machines and caused a short circuit. In order to create more advance
computer, would have needed hundreds of thousands or even millions of tubes, which would have

Essay on Computers and Teaching
Computers and Teaching
Introduction:
"The speed with which technology has developed since the invention of the computer has been
extraordinary and surprisingly sustained. For educators, the rapid and continuing introduction of
new technology into education, has outpaced the ability of teachers and developers to evaluate it
properly, " says Levy, (1997:1). And he continues, that as soon as teachers have become acquainted
with one kind of software and hardware and have developed some ability to use it for educational
purposes, "better" machines appear to displace it.
According to Ahmad et al (1985), computers bring to education what all new technical devices have
brought about: skepticism and fear, or "euphoria followed by...show more content...

computers as part of the class as the pencil, pen, chalk and blackboard. (Classe, 1998)
TEACHER TRAINING:
"In our schools, every classroom in America must be connected to the information superhighway
with computers and good software and well–trained teachers" (Clinton, B: 1996, in Bush et al: 1997)
Teacher training has been supported by different sources, as mentioned by Cwiklik (1997). Federal
funds have been used in programs such as the Technology Innovation Challenge Grant Program,
which provides funds for schools developing projects that encourage the good use of technology in
education. And the Technology Literacy Challenge Fund set up last year for state education agencies
to distribute to school–technology initiatives.
Schools, districts or teachers' certified agencies also sustain programs to develop teacher training,
such as the Community School District One in New York, the New York Public Schools with the
"Project Smart", or the Olympia, WA, School district which devised the original "Generation Why."
All mentioned by Cwiklik in Wall Street Journal (1997).
Teacher training is also left up to teachers who want to initiate participation by themselves, and
enroll in some of the multiple courses offered by colleges all over the USA.
In any case, as Katie Hickox (1997) says, teacher training

Essay about Computers in the Medical Field
"Computers play a key role in almost every sphere of life" (Berry, Terrie). Without them,
everything would be different. People all around the world own or used a computer. Whether you

your everyday life. "No other technology has accessed the world like computers and the use of the
Internet have" (Maddox, Amanda). Without computers, consumers would not be able to do half the
things as quickly as we can. Advances in computer design have increased its use for different
industries, especially in the medical field.

Some surgical procedures are computer–guided. These types of surgeries mean that the patient has
less downtime since the procedures are more straight–forward. Storing information using computers
has changed the way in which the world works. The computer has helped the medical field as much
as or more than other fields (Maddox, Amanda).
In every medical office there are various uses of computers. They contribute a lot to the hospital
administration; all the administrative processes are kept in computers. Staff records, incoming and
outgoing time of the staff, the holiday records of the staff, anything to do with the staff, are all
examples of how computers are used in a medical office. If the doctor were to hand–write every
little thing, to keep track of such things, it would be very difficult, but with computers, the task
uses less time and the process is simplified. In most medical offices, accounting is also
computerized; it helps you keep the daily records of the financial transactions. It also can reduce the
chances of money related frauds because all the data is stored into a computer and can be used for
future reference. Computers also help in recording the names and contact details of the doctors and
associated people and also the patients. It is useful when it comes to recording the medical history of
the patient, such as, previous treatments and tests, diagnosis and symptoms, surgeries, etc. Such

shoes, crafts and vacations are sold over Internet. Even churches rage their members to log on for
their latest news. Last year, new technology made it possible for millions of Internet users to listen to
speeches or traditional radio programs on their computers. That is, thanks to RealAudio, a
technology which converts radio into digital sound. If that weren't enough, video broadcasts and
video–conferencing are being done over the Internet rather than by traditional means . The newest
versions of web browsers allow people all over the world to hold video–conferences and do other
tasks simultaneously. Businesses worldwide have learned to take advantage of the technology and
have begun to work 24 hours a day. Work started in the far east can be sent west and onward before
the sun sets. As with any new industry, the first job holders gained the most advantage. In its
beginning, computer engineering welcomed anyone who was smart and eager to learn. People taught
themselves the skills needed to create web pages. They came to computer engineering with degrees
in physics, English, marketing, biology, journalism, graphic design and maybe computer science.
They might have had experience working in television production or as a
