2. Introduction.
Welcome to this humble website where you will find a basic guide on a
computer. We have focused on describing the different parts and
explaining what each one of them. We assume you are a beginner in that
the "computer" why try to use language as clear and simple as possible. If
you find any errata or confusing explanation, for example, the operation
of any part of the computer, I ask you to leave us a comment or email, to
resolve the question for everyone.
Below you will find a small menu to take you directly to the desired
category. The parties or any computer devices sometimes can be classified
into different categories.
internals
Peripheral or auxiliary devices
multimedia devices

3. 1. Internalparts of a computer, which forms the CPU
Here we list all parts of the "box" computer, which is often called CPU(In
other countries may mean processor or CentralProcessor Unit). Say is the
most importantpart of any computer, that's wherethe data, where
calculations are performed and where everything else is connected are
saved.
1.1. Microprocessor (also called CPU)
The processor with the motherboard and RAM is one of the essential parts
for a computer. Itis usually a small squareof silicon coated with many
gold pins that receives instructions, processes themand sends commands.
Each processor has predefined instructions as addition, subtraction,
multiplication, displacement ... etc. Ithas a small cache memory, which
has very little capacity but is ultra fast. Perhaps you could comparea
processor with a factory receives raw material and finished product
returns. Learn more about the processor here.

4. 1.2. Motherboard or motherboard
This component, sometimes disparaged, is as important as the processor.
The motherboard synchronizes theoperation of all the parts of a
computer, 99% of devices are connected there. If we comparethe
processor with a factory, the motherboard could compare with the road
network surrounding it. Itis a component which is manufactured in
particular thinking processor family and standards in mind. In fact the first
thing we chooseto assemblea computer is the motherboard and then go
looking if it supports certain devices or standards. For examplehow many
video cards can connect, if you have2 or 1 network cards, if it supports
ECC RAM (special memory for servers) ... etc. Find out morehere.
1.3.RAM
RAM is a buffer that stores data and intermediate instructions. Guarda
such as a Word document while you edit in the Office. Itis the second
fastestcomputer 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 reporthas gone from256Kb to 16Gb. On servers you can
even find 64GBor 128GBDDR3 ECCRAM. Learn moreabout RAM here.

5. 1.4. HDD
The hard driveis 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" performanceis much slower than RAM, but
has much more capacity. Currently in 2015 you can find easily-6TB4TB
units, the mostcommon and economical is to have 1-2Tb. Itis also the
component that changes radically technology. Magnetic technology
gradually gives way to the "solid" or "chemistry" of the SSD or Solid State
Drivedisks. Find out more about hard drives here.
1.5. optical readers
Optical readers were very popular in the past. They are basically those
who read all these DVDs, CDs or BluRay discs. Internetnow very
developed in many countries is almost obsolete the disk drive. Any
information can now be downloaded fromthe Internetor you can take it
on a USB stick. Learn all aboutthe reader CDs here.

6. 1.7. Graphics
The video card is the part of your computer that sends the video signalto
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. If you wantto know
more, here wehave written about video cards.
2. Devices or auxiliary devices of a computer.
we probably comes to mind the keyboard. However thereare 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, barcodereaders, the
track pad on a laptop or fingerprintreader. Surely I forgetsome, but on
the Interneteverything can change, so wewill update as weexplain
things.
Mouse2.1
The mouse or mouse is an essential partof any computer. Itis currently
undergoing a technological transformation and perhaps is one of the

7. components that will disappear in the future. Touchscreens quality first
seen in iPhone (really been invented long ago, but never with such quality)
have broughta revolution in the management of not only computers not
mobile, tablet PCs, GPS navigators, watches, mp3, eBook ... etc.
Meanwhile we can enjoy mouse developments as curious as the Magic
Mousefrom Apple. Click here wantto know moreabout the mouse and its
technological advances.
3. Units external storageof a computer.
Currently there are many ways to store information, however we can
subdividethis in two. internal storageand external storagedevices. The
firstcategory is practically only hard drives, while in the second there is
much morevariety ... here for example we find the USB memory, portable
hard drives, memory cards, DVD, BlueRay, floppy ... etc.
4. multimedia devices.
Within multimedia devices, as its name suggests, wecan classify multiple
devices or infinite. We will focus on the mostcommon 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

8. gradually finding their way computing is divided gradually into other areas
... such as Systems Engineering, SoftwareEngineering ... etc. I suspectthat
within a few decades there will be a dozen informática.informáticarelated
careers.
