 An electronic device for storing and processing data,
typically in binary form, according to instructions given to
it in a variable program.

3. FOUR Function of the computer
1.input
2.output
3.processing
4.storage

4. Input devices
The keyboard is
the piece of
computer
hardware used to
input text,
characters, and
other commands
into a computer
or similar devicescanner - an electronic
device that generates a
digital representation of an
image for data input to a
compute
The mouse, sometimes
called a pointer, is a
hand-operated input
device used to
manipulate objects on a
computer screen.
Microphone Is an instrument
for converting sound waves into
electrical energy variations,
which may then be amplified,
transmitted, or recorded

5. Output devices
Speaker is defined as an
electrical device used to
make sound or music
louder
projector an object that is
used to project rays of light,
especially an apparatus with a
system of lenses for projecting
slides or film onto a screen.

earphones typically
joined by a band placed
over the head, for
listening to audio signals
such as music or speech.
printer a machine for
printing text or pictures
onto paper, especially
one linked to a
computer.

6. Process devices
Motherboard a printed circuit
board containing the principal
components of a computer or
other device, with connectors
into which other circuit boards
can be slotted
CPU is the brains of the
computer where most
calculations take place.
a circuit board that
can be inserted in a
computer to give
extra facilities or
memory
Chipsets a collection of
integrated circuits that
form the set needed to
make an electronic
device such as a
computer motherboard
or portable telephone.

7. storage devices
Floppy disc a flexible
removable magnetic
disk, typically encased
in hard plastic, used for
storing data.
memory card a small,
flat flash drive used
especially in digital
cameras and mobile
phones
cd a type of
compact disc able
to store large
amounts of data,
especially high-
resolution
audiovisual
material.
USB an external flash
drive, small enough to
carry on a key ring, that
can be used with any
computer that has a
USB port.

8. Types of computer
 SUPERCOMPUTER-a
particularly powerful
mainframe computer.
• TOWER - is Image result for
tower definition computer
• A computer case, also known
as a computer chassis, tower,
system unit, cabinet, base
unit, or simply case, is the
enclosure that contains most
of the components of a
computer
DESKTOP - a
computer suitable for
use at an ordinary
desk.
MINITOWER -a small
vertical case for a
computer, or a
computer mounted
in such a case

9. Type of computer II
mainframe a large high-
speed computer, especially
one supporting numerous
workstations or peripherals.
the central processing unit
and primary memory of a
computer.
A computer that is
portable and suitable
for use while traveling.
Micro computer a small
computer that contains a
microprocessor as its
central processor.

10. Computer network
.
A computer network is a set of computers connected together for
the purpose of sharing resources. The most common resource
shared today is connection to the Internet. Other shared
resources can include a printer or a file server.

11. Type of Transmission media
The means through which
data is transformed from
one place to another is
called transmission or
communication media.
There are two categories of
transmission media used in
computer communications.
BOUNDED/GUIDED MEDIA.
UNBOUNDED/UNGUIDED
MEDIA.

12. Major parts of the computer
Hard drive a high-
capacity, self-contained
storage device
containing a read-write
mechanism plus one or
more hard disks, inside a
sealed unit. Also called
hard disk drive.
Motherboard a printed
circuit board containing the
principal components of a
computer or other device,
with connectors into which
other circuit boards can be
slotted.
CPU is the abbreviation
for central processing
unit. Sometimes
referred to simply as the
central processor, but
more commonly called
processor, the CPU is
the brains of the
computer where most
calculations take place.
A peripheral is "an
ancillary device used to
put information into
and get information out
of the computer"

13. MAJOR PARTS OF THE COMPUTER
.
A display screen used to provide visual output from a
computer, cable box, video camera, VCR or other video
generating device. Computer monitors use CRT and
LCD technology, while TV monitors use CRT, LCD and
plasma technologies. See analog monitor, digital
monitor and flat panel display.
A computer mouse
is an input device
that is most often
used with a
personal computer.
a printed circuit board
controlling output to a display
screen.
