4. Internal components
CPU
It is the principal
component of the
computer, which it
interprets the instructions
contained in the programs
and processes the
information.
5. Internal components
Mainboard
It is a printed circuit board
to which there connect the
components that
constitute the computer or
computer, and connects
the elements of the
computer.
6. Internal components
Microprocessor
It is the integrated central
and more complex circuit
of an IT system; and there
is in the habit of calling he
by analogy the "brain" of a
computer.
7. Internal components
RAM memory
Is used as a working
memory for the operating
system, programs, and
most software. This is
where all the instructions
the processor running and
other computational units
are loaded
8. Internal components
Power supply
Is a device that supplies
electric power to an
electrical load. The term is
most commonly applied to
electric power converters
that convert one form of
electrical energy to
another.
9. Internal components
Hard disk
Is a data storage device
used for storing and
retrieving digital
information using rapidly
rotating disks coated with
magnetic material. An
HDD retains its data even
when powered off.
10. Internal components
DVD reader
Is a device that plays
discs produced under
both the DVD-Video and
DVD-Audio technical
standards, two different
and incompatible
standards.
12. External components
Mouse
Is an input device that
functions by detecting
two-dimensional motion
relative to its supporting
surface. Physically, a
mouse consists of an
object held under one of
the user's hands, with one
or more buttons.
13. External components
USB port
Is an industry standard
developed in the mid1990s that defines the
cables, connectors and
communications
protocols used in a bus
for connection,
communication, and
power supply between
computers and electronic
devices.
14. External components
Keyboard
Is a typewriter-style
device, which uses an
arrangement of buttons or
keys, to act as mechanical
levers or electronic
switches.
19. External components
Printer
Is a computer peripheral
device that can produce a
permanent range of text
or graphics of documents
stored in electronic form,
by printing on physical
media, usually on paper,
using ink or laser
technology.
