The electronic components of a computer are known as output devices. The output devices of a computer are the parts of the computer hardware that turn data into readable form. Text, graphics, audio, or video can all be used.
“When the computer receives various sorts of data and instructions through input devices such as a keyboard (by typing) and mouse (by clicking), and processes and gives results through output devices such as a monitor and printer, etc.,” is an example of output devices.
The outcomes of data processing in a computer are displayed on output devices. A monitor and a printer are two common examples of output devices. These outputs take machine signals from the device and translate them to human language.
A computer’s monitors are its most important output devices. The computer isn’t complete without it. The monitor is a computer device that allows for the visual display of a wide range of data.
The monitor is intended to show both symbolic and graphical data. On its screen, it displays all of the data and information as a Soft Copy. It serves as a link between the user and the CPU.
To show the data, a cable is connected to a video adapter installed on the computer’s motherboard. The display allows anyone to view files, images, videos, texts, graphics, and tables in real time.
The monitor can display files, photographs, movies, texts, graphics, and tables in real time. They’re becoming thinner and more advanced in terms of technology, such as LED, plasma, and liquid crystal.
A printer is a computer’s electrical external output device that prints digital data on paper as a hard copy. Because the primary function of printers is to convert data from soft to hard copy on a computer,
The printer prints files saved on a computer (text data), which might be tiny or large depending on the page size. Printers are used to print signage, office papers, PPT, and business papers in offices, homes, and businesses.
DPI (dots per inch) resolution is used to measure the resolution or clarity of images generated by a printer. The more dots per fleas a printer has, the higher the print quality and visibility.
The printer is usually connected to a computer via a data cable or through a wireless connection (wifi). Many digital printers now include the latest wireless technologies such as Bluetooth, Wi-Fi, and cloud. As a result, completing the printing operation becomes easy.
A plotter is a type of output device that prints high-quality graphics in a variety of colour formats. It’s similar to a printer, but with more advanced capabilities.
We may use the plotter to print huge maps, architectural drawings, large-format printing, produce photographs, 3D postcards, advertising signs, charts, and various designs of the internal structure of construction machinery, in addition to graphic design.
The plotter can print on cardboard, fabric, film, and other synthetic materials, but the printer can only print on paper. T-shirts, backpacks, other lightweight clothes, and even round things like cups can all be printed on with certain special models.
Plotters differ from printers in that they are more precise, faster, and can produce high-resolution graphics. That is why plotters are employed in engineering disciplines by engineers and architects where precision is required.
Printers create images based on the commands entered into the computer. In this scenario, different coloured pens are utilised to draw multicolor plotters.
Screen Projector and Multimedia
The multimedia screen projector can also be used as a source of output. A multimedia projector is a technological marvel that serves as a useful and multi-functional tool.
You may set up a home theatre in a small space, such as an apartment, because image projection allows us to view the film on the screen across the full wall.
When a projector is used for educational purposes, projects, data graphs, or showcasing documentaries, it is feasible to transmit video in a comprehensive style that allows viewers to better understand content.
We can cast information such as audio, video, photos, and animation from the laptop/computer to the huge screen at the same time using a projector. As a result, it is frequently used in office presentations to make them more interesting and colourful.
Because a multimedia projector’s output results are presented on a huge screen, they can be seen by a big group of people in a meeting/conference room, classroom, or even the hallway.
The parameters of the multimedia projector and the qualities of the screen have a significant impact on video quality. The canvas should have a high reflectivity, as this will improve the screen quality and make it more exact and sharp.
You don’t need to hesitate, for example, if you want to show your PPT in front of thousands of people. You’ll need a projector to project all of your presentation data onto a large wall screen.
