What is Computer?
In simple, Computer is a man made electronics device
which accepts raw data and gives result in high speed. I read this definition
when I was at grade 6. It was one of the boring subjects in my syllabus. As the
time goes on I see the world has changed dramatically. In this world no one can
live without computer and other gadgets.
Modern definition of computer depends upon the
users. For musician computer is a tool to compose music, for engineer it is the
device to trace the building, for the banker it is a device to calculate
principles and interests etc. So, they may be different from each other.
A computer is a programmable machine.
The two principal characteristics of a computer are: it responds to a specific
set of instructions in a well-defined manner and it can extract a prerecorded list of instructions.
