20 Computer Output Devices - How many do you know - Computer Basics 4k

Without an input-output device, computers would not be able to access data and save data. A computer's operating system , like Windows or macOS , is stored on a hard drive and accessed by the computer. Without the hard drive, a computer could not access an operating system and could not function. Without either of those, the computer could not connect to or access the Internet. Because most hardware devices do not require input and output communication with the computer, most IO devices are storage devices. If you are not certain what device is giving you the error, follow the general troubleshooting steps. Otherwise, try following the specific steps for the device giving you the error.

The best way to quickly determine if this is the cause is to try an alternative. If the same error occurs, then you have a problem with the drive. If you can read another disc with no errors, then it may be a bad or dirty disc. Some computer speakers are wireless nowadays, connecting to the computer via Bluetooth. Fun Fact: You can turn your speakers or headphones!

The difference between computer speakers and a microphone is that the frequency of the vibration originates from external sounds rather than data from a computer. Function: As its name suggests, this output device "projects" computer images or video onto a wall or screen. Projectors were first created and used in late 19th-century France. Throughout history, biunial lanterns were used to project ink on glass by photographers, lecturers, and magicians. A biunial lantern is a lantern with projection capabilities. Turning the knob allowed teachers to stop on specific slides. The data projector was invented in Using a single cathode ray tube CRT , the first data projector projected only monochromatically.

Nowadays, projectors are typically used for presentations, watching movies, or as a teaching aid, as they enable an entire roomful of people to see images generated by a single computer. Fun Fact: 3D projectors are designed to project two images of the same thing from different angles at the same time. Wearing 3D glasses, the viewer can see a 3D projection composed of multiple superimposed images. The sender broadcasts signals to 24 satellites that ping to the sender the exact location of the sender computer in the form of latitude and longitude coordinates. The Department of Defense deployed more satellites to bolster the burgeoning navigation system. By , 24 satellites were in orbit and GPS was used broadly across the world in agriculture, aviation, the military, athletics, science, and the list goes on.

A computer sends data to the sound card, which then translates the data into vibrational patterns. These patterns are output by speakers as sound. Function: The sound card controls the output of sound signals, enabling devices like speakers and headphones to work. The sound card is known as an expansion card, which means it can be added to the motherboard. Although a sound card is not essential to a computer's basic functionality, you need one if you wish to play games, watch movies, listen to music, and use audio and video conferencing. PLATO was the first computer-assisted learning system in widespread use.

It wasn't until that sound cards were widely used in PCs. When computer data is sent through a sound card, it is sent to the card digitally. The sound card then translates the digital information in the form of binary, or 0s and 1s into analog information: vibrations, output in the form of sound. Fun Fact: The popularization of sound cards originated in the gaming realm. Sierra Entertainment, a gaming platform, began supporting add-ons like sound cards and this enabled the sound card industry to grow without being an underground solution to a growing issue: shallow sound while gaming.

A video card can greatly improve a computer user's gaming experience. Function: As with the sound card, the video card is an expansion card that slots into the motherboard. The video card processes images and video, enabling visuals to be seen on a display. Most computers have basic video and graphics capabilities built into the computer's motherboard, but for faster, more detailed graphics, a video card is required. The MDA supported visuals such as text and lines for uses such as drafting but didn't offer any graphical experiences. In order to increase the functionality of the burgeoning computing technology, Hercules Computer Technology invented the Hercules Graphics Card, which integrated with the MDA to offer a bitmapped or "rasterized," or pixelated , graphics experience.

From the s on, graphics technology was increasingly like modern-day graphics cards and has increased in graphic quality and speed significantly since then. Fun Fact: Video cards can work in both 2D images and 3D images. Images like browsers, computer desktops, and PDFs are considered 2D images, whereas computer games are considered 3D. A braille reader uses the kinetic nature of the piezoelectric-driven keyboard to send braille letters in the form of raised bumps to the user. Function: A braille reader is a peripheral device that enables a blind person to read text displayed on a computer monitor. The text is sent by the computer to the device, where it is translated into a braille format and made readable by pushing rounded pins up through a flat surface.

Braille readers are also called braille displays and come in various sizes. Braille readers come in the form of separate devices from a keyboard or as part of a keyboard. Most use piezoelectric technology, or electricity generated by mechanical stress, to create a single line of text at a time in the form of raised bumps. This was the case until late when Blitlab proposed an electronic solution to the limited capabilities of braille readers.

Blitlab, upon its release, will allow the visually impaired to use the internet and read books and newspapers more independently. The technology is still in development. Origin Story: Braille is a 63 character alphabet invented in by Louis Braille. Braille was embossed on paper and other materials for decades before braille reader technology was invented. Fun Fact : Blitlab is the first tablet-style braille reader technology that will utilize a perforated glass screen that raises bumps as the computer reads the text from websites and translates it to braille. Function: SGDs, also known as voice output communication aids, generate text to speech.

A user types something and when the command is sent, the SGD reads the sentence out loud. In the s Dynavox was formed by students from Carnegie Mellon University with the goal to make an effective SGD for a young woman with cerebral palsy. This resulted in the invention of the EyeTyper, a device that allowed the user to spell with their eyes that would then be spoken. This often includes the ability to speak. The variety and complexity of output devices evolve with technology. Conceptually output devices have existed for decades. The biunial lantern, for example, sufficed in lieu of a more advanced option for projecting pictures; most output devices like projectors as they are known today didn't come into widespread use until the popularization of computer use at home in the s.

Please leave questions, comments, and concerns in the comments below! I'd love to hear about your experiences with different output devices. I really like your explanation to the above topic Output device. Most the the pupils I teach have no much idea about ICT. Even some have never seen a computer before. Because of these, teaching ICT here is a big problem since every thing mention is new or strange to them. But for what i had from you,I am really grateful. My suggestion is that you should try to add the images of these devices so that pupils like mine can also have the opportunity to see them.

Once again, thank you very much. Social Networking.
