Knowing what a peripheral is, it turns out to be interesting to go a little deeper into the matter to study what are output peripheralsa type contrary to the input ones.
What they will do is, basically, receive and display information from a system so that we can know it, execute it and modify it at our 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 exactly how they work and what they mean for anyone who uses a computer.
What are the output peripherals of a computer and what are their functions?
The peripheral is any additional device that is connected to a computer or system with the intention of allowing data transmission. What the input does is capture, convert and send 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 capable of reproducing it in such a way that the user can perceive and understand it.
It is treated, in this way, in a way we have so our team can communicate with usalthough 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 one hand we have the reception of information that the system is creating, processing, etc.. That is, capture the result of the computer’s process regarding certain data or files with which it is working.
- For the other, the transmission of this information so that it reaches the user in a language that can be interpreted correctly. The ways in which this is possible are the emission of signals, the direct display of content, printing to make the digital physical…
Types and examples of computer output peripherals
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 they make the information reach us visually, that is, that we see it.
tactile
In this case they would be the ones that make We interpret that information received by touch.
auditory
are the ones provide data converted into sound frequencies that we receive through our auditory system.
After knowing the types in which the output peripherals can be classified, we have to provide some examples in which we tell you what they are and how they work, so that you can be aware of how they are providing you with internal information:
Display
A monitor is a screen that is connected to the computer and serves to display on it, through the use of light points, an interface that organizes the information contained on the hard drive, on external drives and in various software as well as its shortcuts and, of course, all the changes we are making, in real time in terms of file creation and deletion, software execution , 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 with it. There are many typeshaving evolved a lot, however, its function remains exactly the same.
Projector
The projector has the same objective as the monitor, display that interface and the movement of information. However, instead of doing it on a screen, this It is a device that launches the signal through the air toas its name tells us, project it onto 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
The speakers are devices that connect to a computer to externalize sounds. These can occur live, for example, those that are achieved in a Skype conversation or watching a streaming concert, be the ones that the team uses to communicate or be audio tracks and other previously captured, recorded and stored content. that can be played at any time.
A speaker makes that digital content transform 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 They have been designed so that there is direct contact between the device and our ears, so that the sound is not reproduced in the environment and, therefore, only the user who is wearing them can hear what is being played.
Tape recorder
Is has only the function of passing 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 used to introduce information, this would be a recorder-player.
Led lights
Forgotten because of how small it usually is, an LED too It offers us certain information based on the color of the light it emits, the frequency of its blinking 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 a software. It can be a video game, a movie, a documentary… What they do is show the content on one or two small screens, this or this being inside a device in the shape of glasses that we put on and that prevents us from seeing anything else. The intention is that we see ourselves immersed in the content, forming part of it.
If these happen to also allow the placement of virtual objectsthat is, the modification of the environment that we are seeing, would become a hybrid, ceasing to form part of the set of visual output peripherals.
plotter
It is a large device that trace graphics, making linear impressions and cutouts. They are from 1 to 12 colors.
printers
Though the printer is considered today a hybrid peripheralwe have not been able to stop mentioning it at this point also because its main function does correspond to the output of information, from the system to reality, making it, moreover, physically, tangible.
It is a device that interprets an image file (.jpeg, .TIFF, etc) and captures it, maintaining its visual characteristics, on a porous surface, generally a paper, by means of color injection, in such a way that it is creates a physical item with a representation of the digital file. Currently there are very sophisticated ones and we even already have 3D printers Far from working with flat images, they are capable of creating all kinds of three-dimensional elements.
machines and tools
They are machines that they work following orders of action of a system and which serve to create solid pieces. These work through an automation of numerical control given by a configuration from an industrial software executed on a computer.
