What is a computer?
Computer is a device for processing information. Computer
has no intelligence by itself and is called hardware. A computer system
is a combination of four elements:
a) Hardware
b) Software
c) Procedures
d) Data/information
Software are the programs that tell the hardware how to perform a task.
Without software instructions, the hardware doesn’t know what to do.
The basic job of the computer is the processing of
information. Computers take information in the form of instructions
called programs and symbols called data. After that they perform various
mathematical and logical operations, and then give the results
(information). Computer is used to convert data into information.
Computer is also used to store information in the digital form.
Computers
Computer is an electronic device that can receive a program
(a set of instructions) and then carry out this program by calculating
numerical information.
The modern world of high technology is possible mainly due
to the development of the computer. Computers have opened up a new
era in manufacturing by means of automation, and they have enhanced
modern communication systems.
Personal computers
Personal computers also called microcomputers or home
computer. The most compact are called laptops. They are portable and
work on build-in batteries.
Personal computers are designed for use at homes, schools,
and offices. At home they can be used for home management (balancing
the family finances, for example) and for playing computer games,
watching films or listening to music. Schoolchildren can use computers
