What is an output device?

Let me first tell you about what is an output. An output is a result that we get after processing our data by the processor so when you give some input to the computer.

Then the computer gives results by processing it is called output and the machine in which you get the result is called computer output devices.

They have no categories in it like computer input devices. They show results after processing it by the CPU. Also, it helps us to get information easily understood by humans. Like your display or monitor in which you are reading this article.

Let’s jump directly into the explanation of computer output devices.

Monitor –

It is an output display device that shows us information in pictorial form. Also, It’s a standard computer output devices.

It works similarly to your mobile display and your television. Monitor Comes in different types and sizes.

Monitors are used everywhere to display computer output data from a computer. So, The size of the monitor is measured diagonally.

The smallest part of the monitor/Display Is pixel. In short a pixel is made up of 3 led/colors called RGB Red Green And Blue. So, the resolution of the monitor is total pixels in the monitor like 720*1280 = 921600 pixels.

Types of Monitor –

CRT – In the older generation of computer CRT Monitor is used CRT Stands for Cathode Ray Tube. Therefore, it is very big and heavy in size and it has an electron gun that works by sending an electron to the front side of the picture tube. That’s why it’s called the CRT display.

TFT – TFT stands for the thin-film transistor in this small transistor and thin films are used to display things. All flat screens are called TFT screens or visual display. It also comes in three types.

LCD – LCD Stands for liquid crystalized display. In these liquid crystals, technology is used.

LED – LED stands for Light Emitting Diode. This is the same led that was used in a torch but in this very small size of LED is used.

OLED Organic light-emitting diode Is used in most of the places. Most important in Samsung phones.

Printer –

I hope you used a printer. In other words, it’s a device used to convert soft copy into hard copy. Also, there are color and black and white printers available in the market.

The most important thing is the quality of printing is measured in DPI Dot per inch and speed or printer is measured in character per second. Computer output devices.

Page per minute and line per minute this differs from the type of printer.

printer - computer output devices

Printer is divided into two categories: impact and non-impact printer.

Impact printer –

Impact printer uses impact to print. As a result, it provides printing by stroking in the Ink ribbon by the Head and it makes lots of noise. Example of an impact printer.

Dot Matrix printer –

If you ever travel in Indian railways then you definitely see the printing of dot matrix printer. The tickets are still printed using a dot matrix printer. Also, It prints in the form of dots.

Non-impact printer –

This uses cartridges to provide printing but this doesn’t provide printing by hammering on the ribbon. It is also a lot more silent than the impact printer. Like inkjet printers use jets to provide printing.

LASER Printer –

For example, do you ever photocopied something? yes! that’s where the laser printer is used it provides printing by heating the paper.

Speaker –

For example, all of us use the speaker to listen to music or songs. Personally I love to listen to raps. Do you?

It converts the signal from the computer to audio signals. Therefore, the speakers are used to listen to the audio.

Plotter –

It is used for printing big graphics banners. Therefore, all the hoardings you see on the roads are printed by the use of a plotter. It is also called a graphics printer.

Projector –

The projector is working similarly to the monitor but the difference is it displays the picture on a very large scale. Also, It uses a high beam to project the picture on the projector panel.

Have you ever visited the movies in cinemas? yes! that’s the place where the projectors are used to show you a movie on large screens.It also used in meetings.

Headphones –

This is a portable device used for listening audio works similar to the speakers but only one person can listen to the audio at a time. Made up of magnet and copper wire.

3D printer –

As the printing technology grows we develop machines to print objects in 3D this is really helpful and efficient. Therefore, a 3D printer is used to print things in 3D.

You can literally print anything in 3D. It works similarly to the printer. In short, It works by using a small nozzle and a roll of plastic tube. Yes it this also counts in computer output devices.

Graphics card (video card)video computer output device.

Graphics card used in heavy graphics things like games and video editing the graphics part of the data is processed by the graphics card and gives output to visual display and makes operation so smooth. Also, this is the category of video computer output devices.

Sound Card –

A sound card is used to give an output of the sound. Therefore, this is mostly used in the studios to get the super sound quality that plugs in the USB socket and it has two audio female sockets one for mic and one for speaker. We can use its input-output device.

V.R BOX –

VR stands for virtual reality this is mainly used in gaming industries it kind of displays fitted in eyeglasses to wear.

After wearing it feels like you are in the gaming world. Also, this works in a whole 360 degree viewing angle. It is also a computer output device.

VR box

Braille display –

It is made for disabled people who can’t see visuals. Therefore it uses braille by emerging from the display.

Also, this display can move up and down its pin. As a result, the user can read the text by touching the display. Computer output devices for blinds.

How output devices work?

When you give input to the computer then the computer processes it by using CPU then it sends to the output device and output device receives it and then gives the results to you. For example, printer.

When you click the print button, the CPU finds the printer in the connected device section and checks if the printer is free or not and sends the document for printing.

SO, The printer takes it jobs and prints the document in the paper and gives it to you and that’s how computer output devices work.

History of output devices –

In the first generation of computers, punch cards were used for input and output both. In short, a punch card is a rectangular paper in which holes punched using machine data are entered in the punchcard first.

After that, a CRT monitor is used to get output. In CRT monitor this data is displayed on the monitor. Also, after monitoring the printer and all other devices are discovered.

First output devices –

The first two computer output devices used to get output by the computer are Monitor and punched card. So, the monitor shows the data in a soft form. The punched card is a hard and physical device.

to clarify, punchcard use to feed data in 12 rows. The first two rows have x and y and then 0 to 9.

The first 5 rows are for reference. Similarly, 6th is for a special symbol and 7 to 72 is for a program statement, and from 73 to 80 is for the serial number.

For example – a single punch card can hold only one statement and a single punch card have 80 columns and 12 rows. Data written using a punch card hole machine.

I hope so, you understand computer output devices. If yes do a comment and tell us.Or have a doubt in computer output devices let us know in the comment section
