COMPUTERS
Computers are used nowadays for many different kinds of work, in offices, banks, factories, hospitals, universities, schools, and many other places.
Their
use is becoming more widespread as cheaper and smaller computers become available. There are three main kinds of computers in use today: the mainframe, the minicomputer and the microcomputer.
What are computers and what can they be used for?
Computers are electronic machines that process information.
They
can accept information in the form of letters and figures, known as the
input
data
.
This
can be put in by various means including keyboard, tape or cards. This data is processed according to a set of instructions called a pro-gram, and the results of this program, the output data can be printed out or shown on a screen.
All the processing is done by a series of arithmetic and logical operations, such as addition, subtraction and deciding whether one number is greater than
another
. The computer itself is known as the hardware, in contrast to the programs which are the software:
Computers can process large amounts of data very quickly, and this is why they are so useful. They can process different types of data, too. A scientist or engineer for example may use a computer to do numerical calculations. A businessman may want to analyze a list of customers or keep a record of how much stock he has. An engineer can produce diagrams and plans on a computer.
Computers are changing our world and civilization in the same way as the invention of the printing press did in the fifteenth century.
