UNIT 1
1. Read the text, try to understand it.
WHAT IS A COMPUTER?
Computers are electronic machines which can accept data in a
certain form, process the data and give the results of the processing
in a specified format as information.
Three basic steps are involved in the process. First, data is fed
into the computer's memory. Then, when the program is run, the
computer performs a set of instructions and processes the data. Fi-
nally, we can see the results (the output) on the screen or in printed
form.
Information in the form of data and programs is known as
software, and the electronic and mechanical parts that make up a
computer is system are called hardware. A standard computer sys
tem consists of three main sections: the central processing unit
(CPU), the main memory and the peripherals.
Perhaps the most influential component is the central process-
ing unit. Its function is to execute program instructions and coordi-
nate the activities of all the other units. In a way, it is the 'brain' of
the computer. The main memory holds the instructions and data
which are currently being processed by the CPU. The peripherals
are the physical units attached to the computer. They include stor-
age devices and input/output devices.
Storage devices (floppy, hard or optical disks) provide a per-
manent storage of both data and programs. Disk drives are used to
handle one or more floppy disks. Input devices enable data to go
into the computer's memory. The most common input devices are
the mouse and the keyboard. Output devices enable us to extract
the finished product from the system. For example, the computer
shows the output on the monitor or prints the results onto paper by
means of a printer.
On the rear panel of the computer there are several ports into
which we can plug a wide range of peripherals-modems, fax ma-
chines, optical drives and scanners.
