【Computer PERIPHERALS】What are they? + Ranking ▷ 2022

in computing, there are many terms with which you may not be very identified but that you have used over time. A clear example of this are the peripherals. In simple words, they are nothing more than elements external to the computer that allow to improve the use of said equipment.

Is considered peripheral to any set of devices that do not belong to the fundamental core of the PC. There are different peripheral ratings and each of them plays an important role in the use of a pc it means.

if you want to know what are peripheralswhat they are for and even their different classifications, you should continue reading.

What are computer peripherals and what are they for?

In more detail, peripherals are all those devices with which a computer communicates with the outside world and that also allow you to store information, serving as auxiliary memory of the main. This type of external devices are totally independent of a computer and its use is so commonwhich are already considered part of it.

An important point to note is that the union gate or link of the peripherals with your equipment, is through USB, COM, etc.. A clear example of peripherals is the mouse, camera, keyboard, flash drive and many other devices that we usually work with in conjunction with a computer.

How are computer peripherals classified and how are they different?

The term peripheral was implemented to refer to any device external to the computer that is optional to use but not essential. However, this has changed over time, as many of these elements have been become essential to a computer system.

So that you know in depth about them, below we will explain the five classifications of peripherals:

input

The input peripherals are all those that They are responsible for capturing and digitizing the data if necessary. They are entered by the user or by another device, and are sent to the computer to be processed.

The most common are:

: serve for enter orders and data into the computer. There are physical keyboards (the most common) or virtual (on-screen or touch keyboards). They come from the typewriter and each key corresponds to one or more characters.
: is of use Handbook and serves as data input or control device. It is used with one of the two hands of the user and the actions carried out through it are reflected with a pointer or arrow on the monitor.
: is used for convertthrough the use of light, images or any other document printed in a digital file. These files are processed with an optical character recognition program (OCR).
Touchpad (touchpad): arose from mouse use. As its name indicates, it is a touch panel that allows the user to control a cursor or facilitate navigation on the computer. They are usually located at the bottom of keyboards.
: They are also known by the name of fingerprint sensor and are capable of reading, saving and identifying a user’s fingerprints to perform different tasks in the computer. For example, they serve as a security mechanism for unlock the computer, an app, etc. Many computers include it.
Webcam (webcam): is a small digital camera that connects to computers to capture images and transmit them on the Internet. Previously they were displayed as standalone devices that you could connect, however, currently come incorporated on many computers.
Microphone: with the help of microphoneI know record all the audios or sounds that you want to record with the help of a computer application for it. In addition, it admits the use of systems of speech or voice recognition to perform different tasks on the computer, such as browsing the web.

Departure

On the other hand, the output peripherals They are responsible for receiving the information processed by the computer and reproducing it.so that it can be perceived by the user. There are many types of them, subdivided according to their functionality. For example, there are peripherals of visual, auditory and tactile output.

Here are some of the most used:

Display: The screen or monitor is one of the main parts of the computer and on it project images, videos and all content that are handled on your computer. In more technical words, it is responsible for displaying the results or processing graphics of a pc. There are different types of monitors: CRT, PDP, LCD, OLED, etc.
Printing machine: with it you can produce physical copies of texts, graphics, documents, and all kinds of files stored electronically. That is, with the help of printing machine can be reproduced documents from the computer to the physical world, through paper or other printing materials.
Speaker: is used for listen to all the sounds emitted by the computer, such as music, sounds or error alerts, conferences, etc. the sound is transmitted by sound waves.
Headphones: They are also known by the term “earphones” and it can be said that they are devices whose purpose is to allow the user both listen how to emit sounds for two-way communication. One is used in each ear and they are detachable, that is, they can be connected and disconnected from a device whenever necessary.

input/output

Input and output peripherals are those devices that They allow both sending information and receiving it. from a computer. Their main function is store or save all the information that is carried out in the equipment.

Among the main input/output peripheral devices are:

Touch screen: is not more than one screen that, with a direct touch on its surface, allows the entry of data and orders to the device. Added to that, it also shows the results that were entered previously. Contact with the touch screen can be established directly with the fingers or with stylus pens.
virtual helmet: are used mostly in video game and collect data from the computer to show them to the user. In turn, the user can make a movement that is picked up by the device and captured in the equipment to be used within the game. game or app. In this classification can be located the holographic glasses.

storage

When reference is made to storage peripherals, it could be said that they are all those that save the data used by the CPU once it is removed from main memory. These types of peripherals can be internal, portable or removable.

Some of the most common are:

: flash memory allows both reading like writing multiple memory locations in the same operation. It is a technology used in USB flash drives and solid state drives.
: is a device storage which is embedded in computers. In their origins they were removableHowever, nowadays they usually come sealed. They can be found from different recognized brands such as Toshiba, Seagate or Western Digital.
: they are not as fast as hard drivesbut are characterized by encode, save and store information using laser beams. Its price is usually lower that of hard drives and even provide elderly Storage capacity.

Communication

Finally, there are the communication peripherals. Their main function is facilitate and allow interaction between two or more computers. They also allow communication with a external computer peripheral.

In summary, some communication peripherals are:

: this device send and receive dataso you can current as a I/O peripheral. Many routers on the market have a built-in modem, so that with just the router you can already establish an Internet connection.
: also known as network interface cards or cards. It is responsible for connecting a computer to a wireless network. It also allows resources to be shared between two or more computers. They may be built into the motherboard or connected via expansion slots.
: It is a feature that has become popular over time. Thanks to this technology, you can transmit files of all kinds from one device to another wirelessly. At present, many computers include this function within their equipment.

What are the main failures with peripherals and their possible solutions?

Like any device, peripherals can present failures for different reasons. Some are much more dangerous than others, so we want to list you some of the main failures together with their possible solutions.

Let’s see next:

Mouse glitch: a very common problem that occurs with the mouse use, is the difficult movement of the cursor. if the mouse is mechanicthere may be dust attached inside the device, so the best solution is to try clean it very carefully.
Keyboard failure: at times, it may be jam one or more keys while working on the computer keyboard. This is a response to a failure in the mechanical device, that is, to a failure with said key. The best solution is to clean it carefully.
Modem failure: the loss of Internet signal It is one of the most common failures when we talk about the modem. It can happen for multiple reasons, such as the network being weak. In these cases, the best solution is contact the internet server.
Headphone failures: many times when connect headphones to the computer, they may not be heard. The reasons for this failure are varied, but one of the most common is that have not connected correctly. To fix it, check that they are in the correct entry and, in case it doesn’t work, probably have been damaged and you must replace them with new ones.
