5. A computer system consists of hardware
components that have been carefully chosen
so that they work well together and software
components or programs that run in the
computer. The main software component is
itself an operating system that manages and
provides services to other programs that can
be run in the computer
6. An input device is a piece of
equipment used to provide
data and control signals to
an information processing
system, such as a computer
or information appliance
7. a small device that a computer user
pushes across a desk surface in order to
point to a place on a display screen and
to select one or more actions to take from
that position.
a peripheral input device modeled
after the typewriter keyboard which
uses an arrangement of buttons or
keys to act as mechanical levers or
electronic switches
8. An output device is any piece of
computer hardware equipment
which converts information into a
human-perceptible form or,
historically, into a physical
machine-readable form for use with
other non-computerized equipment.
9. is an output device that takes images
generated by a computer or Blu-ray
player and reproduce them by projection
onto a screen, wall, or another surface.
are a hardware output device that plug
into a computer line out or speakers port.
Headphones allow you to listen to audio
or watch a movie without disturbing
people around you
10. Computer data storage is a technology
consisting of computer components
and recording media that are used to
retain digital data. It is a core function
and fundamental component of
computers.
11. (random access memory) is a
computer’s short-term memory,
where the data that the processor is
currently using is stored.
flat circular plates made of aluminum or
glass and coated with a magnetic
material. Hard disks for personal
computers can store terabytes (trillions of
bytes) of information
12. Processing devices are the
components responsible for the
processing of information within the
computer system.
13. .
it’s the primary piece of
circuitry that all of the other
pieces plug into to create a
cohesive whole
is a peripheral device that
attaches to the ISA or PCI slot
on a motherboard to enable the
computer to input, process, and
deliver sound
14. Motherboard C P U
The motherboard
is the main
internal hardware
component of
the system unit.
The CPU is a hardware
component responsible
for all operations that is
carried out in the
computer’s system which
is why most computer
users refer to it as the
brain of the computer
and it is held on the
motherboard by a slot.
15. R A M HARD DISK
DRIVE
RAM is the main
memory of the
computer system
whose main
function is to
store data
temporary.
This is an internal
hardware component in
the system unit
positioned closer to the
CD-ROM drive and its
main function is to read
and write from or on a
floppy disk or diskette
16. MICROPROCESSO
R POWER SUPPLY
During operations by
the computer the CPU
produces a lot of heat
and heat could always
cause damage to your
computer, that is why
the CPU fan is put in
place to keep the CPU
under the required
temperature.
Just as any electronic device
needs electrical power to
function, so as the system
unit’s components. But the
components do not work with
the power from your wall
socket so the computer power
supply unit receives the
alternating current (AC) and
converts it to a controlled
direct current (DC) for the
components to function.
