Speakers, headphones, and microphones ports
In informatic , we called peripherals to auxiliaries devices
and independent conected to central processing unit of one
computer. The peripherals of a computer are these parts of
hardware that may be inside of a box, and stored information as
an auxiliary memory from main memory, or comunicate with other
It is known to all peripheral devices that do not belong to
the core of the computer (formed by the computer and the main
memory) allow input and output operations , complementary to
the data processing performed by the computer .
An output peripheralsis an electronic device able to print,
display, or output signals that are easily interpretable by the
user. Basically, an output device has the function to show the
user the result of operations performed or processed by it.
This means that by using the computer output device
communicates and shows us the result of our work, and can easily
observe through the monitor or printer, the two most commonly
used output devices.
There is also other output device, known as speakers or
The input peripherals are system components responsible
for providing data to the computer, and without them it would
be impossible to attempt any operation with it.
While today we can find many attempts to replace these
devices, it is certain that the ease that these offer us for entry
and manipulation of data are practically inimitable, and we have
become so accustomed to its use will be impossible to dispose of
Its function is to enable or facilitate the interaction
between two or more computers or between a computer and
other external peripherals to the among them are the
following: fax Modem, network card, wireless card, Bluetooth
The storage peripherals are devices used to store data
from either a temporary or permanent, which is to manipulate
the computer and can not contain the main memory. In course of
the last few years technology has evolved very quickly and there

A printer port, also known as a parallel port, is a hardware
interface that hooks up peripheral devices, such as printers, to a
central computer system. These ports were originally used to
attach many different types of external devices to a computer,
although the technology has largely been replaced by the
universal serial bus or USB. Before the invention of USB devices,

Speakers port: It is employed for various purposes, but is
mainly used to increase and extend the reproduction of low
frequencies. Also called loudspeaker port.
Headphones port: is the receptor on an audio device that
accepts the headphone plug. Its purpose is to provide an
electrical contact between the media device and the headphones
for transmitting an audio signal. They are output devices,
meaning that the signal will only flow from the media device to
the headphones. They cannot be used to transfer an audio signal
back into the device.
is a small port piece where the
microphone jack is inserted. In most PCs, it located at the rear,
next to the audio piece or in the front.
