Computers

Computer are electronic device that can receive a set of instructions,
or program, and then carry out a program by performing calculations on numbered
data or by compiling and correlating other forms of information. The old world
of technology could not believe about the making of computers. Different types
and sizes of computers find uses throughout our world in the handling of data
including secret governmental files and making banking transactions to private
household accounts. Computers have opened up a new world in manufacturing
through the developments of automation, and they have made modern communication
systems. They are great tools in almost everything you want to do research and
applied technology, including constructing models of the universe to producing
tomorrow's weather reports, and their use has in itself opened up new areas of
development. Database services and computer networks make available a great
variety of information sources. The same new designs also make possible ideas of
privacy and of restricted information sources, but computer crime has become a
very important risk that society must face if it would enjoy the benefits of
modern technology. Two main types of computers are in use today, analog and
digital, although the term computer is often used to mean only the digital type.
Everything that a digital computer does is based on one operation the ability to
determine if a switch, or gate is open or closed. That is, the computer can
recognize only two states in any of its microscopic circuits on or off, high
voltage or low voltage, or—in the case of numbers—0 or 1. The speed at which the
computer performs this simple act, however, is what makes it a marvel of modern
technology. Computer speeds are measured in megaHertz, or millions of cycles per
second. A computer with a "clock speed" of 10 mHz—a fairly representative speed
for a microcomputer—is capable of executing 10 million discrete operations each
second. Business microcomputers can perform 15 to 40 million operations per
second, and supercomputers used in research and defense applications attain
speeds of billions of cycles per second. Digital computer speed and calculating
power are further enhanced by the amount of data handled during each cycle. If a
computer checks only one switch at a time, that switch can represent only two
commands or numbers; thus ON would symbolize one operation or number, and OFF
would symbolize another. By checking group...
