What is an output device and and its types


do you know What is Output Device And which is the output device in the computer. This Knowledge of Computer Fundamentals. Everyone should be aware of these I/O devices. We Computer, Mobile, Tablets, like electronics are surrounded by devices. We have started spending most of the time with these devices. To make these devices Hardware is used.

If we talk about the hardware components of the computer. some of which are Keyboard, Mouse, Motherboard, Speaker, RAM, Hard disk, DVD drive, Monitor. You will get to see these devices in every computer. Some of which are Input Device, Output Device, Processing and Storage Device. By the way, in some of my earlier articles, you have been given information about some of these devices. But in today’s article, a special hardware of computer, What is Output Device will learn about.

What is Output Device – What is Output Device in Hindi

Output devices are hardware that can be used to display text and graphics. Output devices usually consist of a screen, but they can also be printers, projectors, or audio devices. They are connected to the computer through cables. Computer output devices are often used to display information to the user on their screen. For example, printers are commonly used to make hard copies of documents created using word processing software programs on computers.

Input Device

OUT means to keep out and PUT means to keep, complete means to keep out. This device shows the process data out. EX- Monitor, Speaker, Printer, Projector, Plotter.

In Monitor we movie, File, folders, apps, menu, desktop etc all are seen on this device. Now you can also see the things written on the same monitor. Whether it is mobile or tablet. When you listen to songs in the speaker, that too brings out the sound of the outside. The printer also sends out printout. So let’s know about the Types of Output Devices in detail.

Output device type

Here I have told you about the output device list. We cannot tell about all but will give complete information about some parts of the output device. So let’s know about them.

1. Monitor

It is an electronic device that shows some output for computers. It looks just like a TV. A big and good display resolution helps us to show fine graphics. This hardware, Produces Video and Graphics using video card. Just like the TV is hung on the wall, similarly the monitor is kept on the desk. It is used to view Video, Image, Document, App in computer. If there is no monitor then what is going on inside the computer. We do not know where to click.

Monitor also has some other names

Sometimes monitors are also known by these names screen, display, video display, video display terminal, video display unit and video screen. Sometimes they are also called computers due to lack of knowledge. The reality is this. This monitor is also one of the remaining hardware of computers. Shutting down the computer and turning off the monitor are two different things.

Facts about Monitor

HDMI, DVI, and Monitor is connected to VGA port. Other connectors are USB, Display Port, and Thunderbolt. Before buying a new monitor, one thing should be kept in mind that both the connectors should be same. If your computer supports VGA and you have brought a monitor, then the HDMI port will not be of any use. By the way, nowadays Multi Port Monitors are available in the market.

There are two types of this

  1. CRT Monitor:
    They are heavy and big and use up a lot of desk space and electricity. This is the oldest used technology. It is based on cathode ray tube technology. Which were made for television. But these monitors do not work nowadays.
  2. 2. LCD Monitor:
    There is a type of flat panel display. This is a newer technology than CRT. These monitors use less desk space. It is of less weight. These monitors use less electricity. These monitors are being used for a long time. On laptops and notebook computers, they also act as touchscreens. On tablet computers, mobile phones.

2. Printer

Printer is an output device. Which prints the information received from the computer on paper. This copy of the output on paper It is called hard copy. The output of the document from the computer is very fast and the printer is not able to work so fast. Therefore, a need was felt that the information could be stored in the printer itself. That’s why the printer also has a memory from where it prints the results slowly.

According to the use of technology, there are many types of printers. Whose information has already been given below.


It is similar to a ball-head typewriter. This type of printer has a wheel made of plastic or metal. on which the characters remain. Pressed against a vibrating ribbon. On which a character remains. When this pressure falls on the white paper then a character is formed. You can print very clean characters with this printer but graphics ones cannot.


In this, the character is formed after striking the pins against the ink ribbon. When the pin hits the paper once, then a dot is formed there and a character is formed by the union of many dots.
Ink-jet: Ink is sprayed on a plain paper which is drawn on high quality text and graphics paper.

Laser Printer

The technology used in the xerox machine is also in this technology. You can also print very high quality text and graphics from Laser Printers.

Line Printer

In this, there are many Pins or Characters in a single line. Which takes very less time to print a Sentence. Despite being very fast, this printer prints low quality content.

Thermal Printer

It has Thermal in its name. Meaning heat sensitive paper is used in this. Heat Pins are pushed into Heat Sensitive Paper. It is used in Calculators and Fax Machine.

Characteristics of the printer

  • Quality:
    The letters of the output which are printed from the printers. They have been divided into these 3 Qualities. We can call them Letter quality, near letter quality or Draft quality. Letter quality printer’s names are daisy-wheel, ink-jet, and laser printers.
  • Speed:
    Talking about the speed of printers, their measurement is shown by characters per second (cps). The higher the CPS, the better the printer. The name of the slowest printer is Daisy-wheel whose speed is 30 cps. Line printers speed is one of the fastest printers whose speed is 3000 cps. Dot-matrix printers 500 cps and laser printers produce 4 to 20 text pages in a minute.
  • Impact or non-impact:
    Printers that strike ink ribbons come in the category of Impact printers. Daisy-wheel, dot-matrix, and line printers all fall into the category of ‘impact printers’. Their names are laser printers and ink-jet printers, both of which fall under the category of non-impact printers. There is only one difference between impact and non-impact printer’s, impact printer’s make excessive noise.
  • Graphics:
    Some printers like daisy-wheel and line printers can print only text. The rest can print both Text and Graphics Images.
  • Fonts:
    Dot-matrix printers have fonts of some counting minutes. If we talk about laser and ink-jet printers in which there are countless fonts. Daisy-wheel printers also have a number of selected printers.

3. Plotter

Plotter is used to obtain high quality drawings and graphs on large paper. It is mainly used in engineering, building construction, city planning, map etc.

There is an AC Output Device that draws pictures according to the commands given by the computers. There is a lot of difference between Plotter and Printers, in which Pen is used to draw something. Multicolor Plotters Pens of different colors are used.

If it is about money, then this device is much more expensive than printers. They are used in Engineering Application.

4. Screen Projector

Projector is also an output device. With its use, all the motion methods of the computer’s screen are shown on the big screen. Using this we can show presentations.

The output of this device can be displayed on a wall or on a white screen. Generally, the surface on which the light is projected should be large, straight and of white color in surface size. Projectors are used to play moving images, slideshows and videos. Presentation can be shown to a large number of people. The size of this device is also small and the weight is also less.

Where is the projector used?

  • PowerPoint presentation to business meeting. Project is done in.
  • Projector is used to explain the children in class.
  • To play multimedia (movies) in TV and computer on the big screen through Projector.
  • In Public Places, it is used to explain any goods or services to the people.
  • To display different types of pictures on an empty wall, which can change the look.
  • HDMI or VGA cables are used to connect projectors to computers.

5. Speaker

Using this we can hear sound. It presents a soft copy of the output in the form of sound. The language of computers is the speaker. It is an output and hardware device. Which generates sound from computers. The sound produced by Computer Speakers is generated by a component of the computer whose name is the sound card. Speaker already resides in LAPTOP at the top end of the keyboard.

how does it work

Speakers – are made from a cone, an iron coil, a magnet, and a housing (case). When the speaker receives electrical input from a device, it causes it to move back and forth. A vibration is created and due to this vibration, the sound comes out. You can hear this voice with your own ears.

The quality of sounds is determined by a frequency response, Total Harmonic Distortion and Watts.

my final opinion on this article

It is always my endeavor that you get correct and precise and complete information. You probably learned all this What is Output Device And how many types of output devices are there in the computer. Now the size of all the output devices that will come in future is getting smaller day by day. Computer Scientist are making so many small computers in which all the components are attached in a single device. After a few years, the monitor will come out of a hole, which is also called Laser Monitor. Technology is never going to stop guys.
