Definition Of A Computer by tvreporter: 2:48pm On Jul 10, 2015 |
Almost all of us are involved, in
some fashion, with computers on a
daily basis. Without computers, life
would certainly be a lot different.
Computers, however, are relatively
new on the human scene.
Definition of A Computer: A
computer may be defined as a
machine that can solve problems by
accepting data, performing certain
operations and presenting the
results of those operations under
the direction of detailed step-by-
step instructions. Such a set of
sequenced instructions, which cause
a computer to perform particular
operations, is called a program.
An electronic device for the
storage and processing of
information.
A programmable machine that
inputs, processes and outputs data.
An electronic device that stores,
retrieves, and processes data, and
can be programmed with
instructions. A computer is
composed of hardware and
software, and can exist in a variety
of sizes and configurations.
CONSTITUENTS OF A
COMPUTER
All the elements that go together
to make a PC fall into one of two
categories, hardware or software
You simply can’t have one without
the other. All the parts of a
computer that you can physically
see or touch are called hardware.
This following list represents a
basic set of hardware found in most
PCs.
PC Case
Motherboard
Power Supply
Hard Disk Drive (HDD)
Floppy Disk Drive (FDD)
Compact Disk Drive (CDD)
Digital Video Disk drive (DVD)
Monitors (CRT and LCD)
Keyboard
Mouse
Audio
Cables & Wires
COMPUTER SOFTWARE
Computer software (or simply
software) is a program that enables
a computer to perform a specific
task, as opposed to the physical
components of the system
(hardware). This includes
application software such as a word
processor, which enables a user to
perform a task, and system
software such as an operating
system, which enables other
software to run properly, by
interfacing with hardware and with
other software.
