Knowing what a peripheral is, it is interesting to go a little deeper into the subject to study what are the peripheral output , a type contrary to the input.
What these will do will basically be to receive and display information from a system so that we can know it, execute it and modify it for convenience.
What we will do is explain in detail what they are and what they are for, in addition to classifying them and giving you examples so that you know perfectly what their operation is and what they mean for anyone who uses a computer.

What are and what are the peripheral output of a computer and What functions do they have?
The peripheral is any additional device that connects to a device or system with the intention of allowing data transmission. The input is what it captures, converts and sends information from the environment to the system; Now we will see the opposite case.
Definition
The output peripheral is that device that receives information previously processed by a system and is able to reproduce it so that the user can perceive and understand it .
It is treated, in this way, in a way that we have so that our team can communicate with us , although it is only done in this direction.
Functions
I know its own definition, which is very basic and simple as well as explanatory, we have the function that these devices have, which is double.
- On the one hand we have the reception of information that the system is creating, processing, etc. . That is, to capture the result of the computer process regarding certain data or files with which you are working.
- On the other, the transmission of this information so that it reaches the user in a language that I can interpret correctly. The ways in which this is made possible are the emission of signals, the direct sample of the contents, the impression to make the digital physical …
Types and examples of output peripherals of a computer
We can make a very basic classification based on the senses that are stimulated with the results of the information projection. This includes visual, tactile and auditory devices.
Visuals
Visual output peripherals are those that make information come to us visually, that is, we see it .
Tactiles
In this case they would be the ones that make that information received be interpreted by touch .
Auditory
They are the ones that offer data converted into sound frequencies that we receive through our auditory system.
After knowing the types in which you can classify the output peripherals , we can provide some examples in which we tell you what they are and how they work, so that you can be aware of how you They are providing internal information.
Monitor
A monitor is a screen that connects to the computer and is used to display on it, through the use of luminous dots, an interface that orders the information contained in the hard disk, in external units and in various softwares as well as their shortcuts and, of course, all the changes that we are making, in real time in terms of creation and deletion of files, execution of softwares, configuration of elements of all kinds, etc.
In short, it is the device that shows how the system information is distributed and how we are working it. There are many types , having evolved a lot, however, its function remains exactly the same.
Projector
The projector has the same objective as the monitor, show that interface and the movement of information . However, instead of doing it on a screen, this is a device that throws the signal through the air to , as its name indicates, project it on another surface , such as a panel or the wall itself. The result is of worse quality but as a positive point we have that the projection can be large.
Speakers
Speakers are devices that connect to a computer to outsource sounds . These can occur live, for example, those that are achieved in a conversation on Skype or watching a concert in streaming, be the ones that the team uses to communicate or be audio tracks and other content previously captured, recorded and stored that can be played at any time you want.
The speaker causes that digital content to be transformed into sound, emitted as waves to disperse in our environment and that we receive it through the ear. It is, therefore, a sound or auditory output device.
Headphones
The headphones work the same way as the speaker . The difference is that these have been designed so that there is a direct contact between the device and our ear, so that the sound does not play in the environment and, therefore, only the user who wearing them can hear what is being played.
Recorder
This has only the function of transferring digital elements to a disk drive such as DVD, CD, etc. For this reason, we are talking about an output peripheral and not a hybrid because, we emphasize, it is not useful to enter information, this would be a recorder-player.
LED
Forgotten how small it usually is, an LED also offers us some information depending on the color of the light it emits, the frequency of its flickering or the mere fact of being on or off . It is therefore a small visual element of output.
Virtual reality glasses
These serve to show us a virtual reality generated by software . It can be a video game, a movie, a documentary … What they do is show on one or two small screens the content, being this or is inside a device shaped like glasses that we put on and that prevents us from seeing something else. The intention is that we will be immersed in the content, being part of it.
If these also allow the placement of virtual objects , that is, the modification of the environment we are seeing, they would become a hybrid, ceasing to be part of the set of visual output peripherals .
Plóter
It is a large device that plots graphics, making linear prints . There are 1 to 12 colors.
Printer
Although the printer is considered today a hybrid peripheral , we could not fail to mention it at this point also because its main function does correspond to the output of information, from the system to reality, also becoming physically, tangible.
It is an apparatus that interprets an image file (.jpeg, .TIFF, etc.) and captures it, maintaining its visual characteristics, on a porous surface, usually a paper, by means of color injection, so that it is creates a physical element with a representation of the digital file .
Currently there are very sophisticated and we even have 3D printers that, far from working flat images, are capable of creating all kinds of three-dimensional elements.
Machine tools h3>
These are machines that work according to the orders of action of a system and which are used to create solid pieces . These work through an automation of numerical control given by a configuration based on an industrial software running on a computer.
