2. EXTERNAL PARTS
DISPLAY: It is an output device that, using an
interface displays the results of processing a computer.
The monitor concept was first defined by Charles
Antony Richard Hoare in a 1974 article.
MOUSE: is a peripheral input electronic computer
use, generally made of plastic, used as input or control
data. It is used with one of the user's hands and
detects its relative movement in two dimensions by the
horizontal surface on which it rests, usually reflected by
a pointer or arrow on the monitor.

3. KEYBOARD: Is a peripheral or device that consists
of a set of keys, such as a typewriter, which allows
data to a computer or digital device. The keyboards are
composed of different types of keys that are
alphanumeric and keys, scoring special.
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

4. user, it consists of specific internal parts which will be
explained later.
GABINETE: 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.

5. SPEAKERS: The speakers are used to listen to
sounds from the computer to listen to music or sounds
of errors, etc.
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.

6. BUG: Electronic Instrument designed to capture
sound waves and transform them into electrical
oscillations .
SCANNER: is a peripheral that is used to convert, by
using light, or any other printed images to digital
format.

7. INTERNAL PARTS
POWER SUPPLY: The power supply is extremely
important in any computer equipment accessory
because it stores the energy of the team and if the
power goes out, allows you to save documents and
turn off the computer without loss of information

8. MICROPROCESSOR: that also will call processor
or CPU (Central Processing Unit - Central Processing
Unit) is the brain of a computer. This is responsible for
taking the information received from different sources,
make the necessary processes this information and
send the result to the destination is indicated

9. MEMORIES: is where your computer stores
programs and data you are using. There are two types
of memory: RAM (Random Access Memory). It is
composed of one or more chips and used as working
memory where you can save or delete our programs
and data. And the ROM (Read Only Memory) Consist
and in a chip that has taxed a number of programs and
essential data for computer operation: boot system,
basic hardware control, diagnosis
HARD DRIVE: is a device non-volatile storage, ie
retains information that has been stored correctly even
with the loss of energy, it uses a digital magnetic
recording is where it is in most cases stored the
operating system of the computer.

10. VIDEO CARD: is an expansion card for a computer,
responsible for processing the data from the CPU and
turn them into comprehensible information and
representable in an output device such as a monitor or
TV.
SOUND CARD: is a computer expansion card that
allows audio input and output under the control of a
computer program called Driver

11. MOTHERBOARD: is a card where are located the
key components of a computer. Contains the
microprocessor, memory and other circuits that are
essential to the functioning of the PC.

12. FANS: is a fan that is in the processor that allows
cool the components on the motherboard.
