2. INTERNAL PARTS OF THE
COMPUTER

3. Microprocessor
(also called CPU)
The processor with the motherboard and
RAM is one of the essential parts for a
computer. It is usually a small square of
silicon coated with many gold pins that
receives instructions, processes them
and sends commands. Each processor has
predefined instructions as addition,
subtraction, multiplication, displacement
... etc. It has a small cache memory,
which has very little capacity but is ultra
fast. Perhaps you could compare a
processor with a factory receives raw
material and finished product returns.
FUNCTION:
A microprocessor controls all functions
of the CPU, or central processing unit, a
computer or other digital device. The
microprocessor operates as an artificial
brain.

4. Motherboard or
motherboard
This component, sometimes disparaged, is as
important as the processor. The motherboard
synchronizes the operation of all the parts of
a computer, 99% of devices are connected
there. If we compare the processor with a
factory, the motherboard could compare with
the road network surrounding it. It is a
component which is manufactured in particular
thinking processor family and standards in
mind.
FUNCTION:
The function of the motherboard of the
computer is acting as the main circuit that
connects and communicates to all devices and
components connected to it. Also, the
motherboard facilitates communication
between devices. Are designed according to
the type of central processing unit (CPU,
after its acronym in English) which will be
installed

5. RAM
RAM is a buffer that stores data and
intermediate instructions. Guarda such
as a Word document while you edit in
the Office. It is the second fastest
computer memory after the cache. All
data stored there are deleted when we
turn off the computer unlike for
example hard disk. In recent years this
report has gone from 256Kb to 16Gb.
On servers you can even find 64GB or
128GB of ECC DDR3 RAM
Function:
Stores programs and data, starting at
low addresses and reaches the beginning
of the ROM.

6. ROM
The read-only memory, also known as
ROM (acronym for read-only
memory) is a storage medium used in
computers and electronic devices,
which allows only reading of
information and not your writing,
regardless of the presence or a
power source.
Function:
Located in the high memory
locations, stores basic computer
routines, such as disk access
routines, screen, etc.

7. HDD
The hard drive is one of the essential
components of our computer system.
Generally it is an internal part of any
computer, although in recent years it
has popularized the external format,
basically the technology is the same.
The "Hard Drive" performance is much
slower than RAM, but has much more
capacity. Currently in 2015 you can
find easily-6TB 4TB units, the most
common and economical is to have 1-
2Tb.
FUNCTION:
It is the heart of the computer, the
files, programs and entire operating
system emptied (because without the
machine would not work)

8. optical readers
Optical readers were very popular in
the past. They are basically those who
read all these DVDs, CDs or BluRay
discs. Internet now very developed in
many countries is almost obsolete the
disk drive. Any information can now
be downloaded from the Internet or
you can take it on a USB stick.
FUNCTION:
Optical readers are responsible for
officiating as an input device, and can
enter data the way you develop then
without a keyboard but previously
used to use the communication port of
the same, something that has been
neglected by the installation of,
among others, the USB port.

9. Graphics card
The video card is the part of your computer
that sends the video signal to your monitor
or TV. Virtually alone is a small computer
because the board has a processor, RAM,
BIOS, power inputs ... etc. They are
essential for people looking mostly play or
video editing or 3D.
FUNCTION:
The graphics card is responsible for
everything other images.

It has its own chips (including own
microprocessor) and its own RAM. It has
become almost on a computer inside your
computer. And that because he has a tough
job: convert digital signal (ones and zeros) in
points of light and color.

10. Peripheral or auxiliary devices of a computer.
we probably comes to mind the keyboard. However there
are a few input devices described. Usually here we classify
devices used to send orders to our CPU, which will be
processed and stored or displayed by output units of
information. For example mouse, graphics tablets, barcode
readers, the track pad on a laptop or fingerprint reader.
Surely I forget some, but on the Internet everything can
change, so we will update as we explain things

11. Mouse
The mouse or mouse is an essential
part of any computer. It is currently
undergoing a technological
transformation and perhaps is one of
the components that will disappear in
the future. Touchscreens quality first
seen in iPhone (really been invented
long ago, but never with such quality)
have brought a revolution in the
management of not only computers
not mobile, tablet PCs, GPS
navigators, watches, mp3, eBook ...
etc.
FUNCTION:
The mouse or mouse to have a specific
and practical functionality makes its
internal structure nosea very complex,
despite its external interface that is
simple and easy to use for elusuario.

12. External storage of a computer.
Currently there are many ways to store information,
however we can subdivide this in two. internal storage
and external storage devices. The first category is
practically only hard drives, while in the second there
is much more variety ... here for example we find the
USB memory, portable hard drives, memory cards,
DVD, BlueRay, floppy ... etc.

13. multimedia devices.
Within multimedia devices, as its name suggests, we can classify
multiple devices or infinite. We will focus on the most common devices.
Such as printer, scanner, speakers, headphones or video camera.
Actually these components could be classified as devices E / S (Input /
Output) information. A scanner would be an input device while the
output printer serious.
Remember also that there is no real truth in computing, engineering
indeed although sometimes call even missing a few years to be as such
(unfortunately). For me it is not a science entirely accurate as it could
be mathematical or engineering of roads. Also in the background it is
really complex and no human being can be an expert in all areas. In fact
now gradually finding their way computing is divided gradually into
other areas ... such as Systems Engineering, Software Engineering ...
etc. I suspect that within a few decades there will be a dozen
informatics. informatics related careers.

14. external parts of computer

15. Keyboard:
is a device that
It allows you to enter information
it written to the computer, it is
composed of keys, which when
pressed reflect characters
the (letters, numbers, screen
symbols).
FUNCTION:
Keyboard functions are categorized
by their keys:
The mouse or mouse to have a specific
and practical functionality makes its
internal structure nosea very complex,
despite its external interface that is
simple and easy to use for elusuario.

16. MONITOR:
an output device through an
interface, it shows the results of
processing a computer. The monitor
concept was first defined by Charles
Antony Richard Hoare in a 1974
article.
Function:
1-receive information and
data
2-open programs, files
3-internet access

17. CPU
Central Processing Unit, this is the most
important part because it is the brain of
the computer, inside her commanded all
tasks are performed by the user, it
consists of specific internal parts which
will be explained later.
function
Main functions of the processor or CPU:
. Send and receive control signals,
memory addresses and data from one
place to another computer via calls BUS
lines.
. These doors are bus I / S, which
connect to the memory and support
chips bus.
. The data passed through these doors I
/ S while traveling to and from the CPU.

18. cabinet
The cabinet is the outside of the
computer and there are two main
types, tower and desktop. In class
tower, there are mini tower, mid
tower and full tower which are used
for servers. Inside the case are all
major devices.
FUNCTION
protect the internal parts of the
Computer
(Hardware) as would be the
motherboard, processor, RAM, hard
drive, etc ... because with a simple
touch or move your hand over one of
these components can cause damage
as they are very bulnerables to
electrostatic, touch, etc...

19. PEAKERS:
The speakers are used to listen to
sounds from the computer to listen to
music or sounds of errors, etc.
FUNCTION:
They are purely recreational purpose,
mainly to listen to music and system
sounds, although speakers versions 5.1,
are used to hear the sound of action
movies and video games mainly.
The speakers let you hear different
kinds of sounds emitted by the
computer, which sometimes indicate
something in particular.

20. PRINTERS:
is a computer peripheral that allows a
permanent copy of text or graphics of
documents stored in electronic form,
printing paper gloss data on physical
media, usually paper or transparencies,
using ink or laser technology.
FUNCTION:
It allows a permanent copy of text or
graphics of documents stored in
electronic form, printing it on physical
media, usually paper or transparencies,
using ink or laser technology.

21. BUG
Electronic Instrument
designed to capture sound
waves and transform them
into electrical oscillations.
FUNCTION:
Its function is to translate
the vibrations due to acoustic
pressure on the capsule by
the sound waves into
electrical energy, which
allows for example to record
sounds of any place or item.
The microphone lets you
enter information in the form
of sound, such as writing a
letter in which the same
computer could write it for
you.

22. SCANNER
is a peripheral that is used to
convert, by using light, or any other
printed images to digital format.
FUNCTION:
The function of a scanner is to scan,
recognize and automatically archive
any document, however not all
scanners fulfill these functions.
