The computer is now a certain need of this generation. And output devices of computers work as alliances. They transfer information from the computer to users into readable form.
Without output devices, it becomes difficult to run a computer. So, we must have a little knowledge about them.
Here, we’ll discuss a few inevitable output devices that you need, along with their features, working process, and where you can get them. So, keep reading until you’re finished.
What Is A Computer Output Device And Why You Need Them?
Most of us are familiar with monitors, speakers, headphones, etc. These essential tools are known as output devices. Without a few of them, running a computer is quite challenging.
The output devices usually run data from the computer to another device or the user. In short words, output devices transform processed data in audio, video, or text form.
It’s possible to run a computer without using output devices, though. However, it’ll be difficult to foretell what your computer is doing in this manner. You’ll get no indication of errors or a way to provide additional input.
How Does An Output Device of Computer Work?
When the computer completes processing input data, it sends a signal to an output device. And an output device receives the signal and shows it to us.
For example, if you type H on your keyboard (Input Device), the computer receives the data. Then it shows us through the monitor (Output Device).
Thus, a printing machine (Output Device) comes to play if you need to print out that H letter. That’s how output devices work, receiving signals and outputs to us.
9 Most Essential Output Devices of Computer
Output devices are now being used everywhere. Whether you’re in a mall or railway station, you’ll see their various uses.
Here are the nine most-used output devices you should know.
Monitor
Monitor, as we know, is an essential part of a computer. It helps us to operate the PC by providing a visual representation of all the information from the computer.
It usually displays data in graphical or symbolic form. We get the soft copy of processed data through the monitor.
You can see photos, videos, files, texts, graphics, and tables on the screen through it. In a sense, it serves as an interface between the CPU and the users.
Mainly, there are 2 types of monitors. They’re known as CCFL and LED. The difference is based on backlighting. But despite their difference, you can easily set them up in the following way:
- Locate the monitor’s connector cable
- Attach the cable with the video ports located at the back of the monitor
- Install the cable in the CPU as well
- Plug in the monitor power cord
- Put the monitor power cord in the power outlet
Now when you turn on your PC, the monitor should work just fine.
Printer
A printer is a device that transforms the soft copy of a file into a hard copy on paper.
In other words, it prints digital information from the computer onto pages, for example, printing office documents, documents, PPT documents, signs, etc. Depending on the information or paper size, the letter can be small or large.
Usually, it’s connected to a computer via a data cable or wireless connection (Wi-Fi). Many digital printers now have the most up-to-date wireless technologies, such as Bluetooth, Wi-Fi, and cloud. As a result, completing the printing operation becomes easy.
At present, there are different types of printers for different purposes. Here are some:
- Solid ink printer
- Laser printer
- Business inkjet printer
- Home inkjet printer
- LED primer
- Multifunction printer
- Dot matrix printer
- 3D printer
Screen Projector
The multimedia screen projector performs as both an input and an output device. It’s a multifunctional device, useful for different types of tasks.
We can cast audio, video, graphics, or animation from our laptop to the big screen simultaneously using a projector.
You can set a home theatre across the entire wall with a screen projector. It is really easy to cast movies on a large surface.
A projector isn’t used for only office or commercial purposes, but also for educational purposes; it’s possible to transmit video comprehensively. And that allows viewers an extensive view for understanding the content in a better way.
Speaker
A computer speaker is a device that generates sounds. It processes the audio signals it receives and outputs them as audible sounds. Speaker is not its technical name, though. Its proper name is “Dynamic head.”
It’s now available on various devices, including televisions, radios, phones, and children’s toys. Many laptops come with a built-in speaker towards the top of the keyboard.
Headphones
Just like a speaker, headphones deliver audio as well. But the difference is, it transits concealed audio. Only you can listen to what’s going on.
With this, you can avoid disturbing others while enjoying any audio. And audio sounds become very clear with headphones. Nowadays, many headphones with advanced technology can connect to any musical device with a jack port of up to 3.5MM.
Video Card
The video card is another inevitable output device. Every computer user, especially gamers, is well aware of how essential it is. This component is known as a video adapter as well.
Besides, a video card is responsible for processing and translating data or machine code to a practical image. It summarizes the computer code to a user-friendly image on the monitor, television, or any other display in the process.
Sound Card
The sound card is an expansion of computers. It’s basically used to receive and send audio signals. Sound cards use software and device driver to work. Here microphone works as an input device, while a speaker works as an output device.
Once the sound card receives a digital audio signal, it converts that data into an analog signal. This analog signal is then played by the speaker. The reverse happens here as well.
The sound card receives incoming analog audio sound, converts it into a digital signal. This signal is then sent to the receiver.
GPS (Global Positioning System)
GPS is a satellite navigation device that determines time and location. It works under all weather circumstances.
This device lets us locate the desired object on a map, regardless of its place on the globe. The primary function of GPS is to provide position, weather information, and tracking.
Almost every modern laptop and computer has GPS navigation on their smartphone or tablet. For persons of various vocations and occupational needs, the necessity for GPS can arise at any time.
Braille Reader
Everyone knows what braille is. It’s a system for blind people to read texts. A blind person can comprehend texts by touching engraved patterns. Thanks to modern technology, this feature is not available for computers as well.
A braille reader is an output device that converts the displayed texts into brailed patterns. The whole device is basically a flat device with rounded pins.
These rounded pins raise in accordance with the displayed texts. Blind people touch these texts and immediately know what the text is.
How To Take Care Of Output Devices
Cleaning is the major and the most effective way of taking care of devices. But, whenever you work with electronic equipment, there’re always some precautions you should take.
The best way to clean any computer component or device is to follow the manufacturer’s instructions in the user’s guide. Here are a few things you can do:
- Always turn off the system first
- Wear an anti-static wrist strap
- Never work on carpeted floors
- Don’t spray cleaning fluids directly on computer components
- Always spray the cleaner on a cloth first and then wipe it off
- Never let the detergent or drip run near circuit boards or connectors in device housings
- Keep a cautious eye so that the circuits or electronics don’t get wet
- Some cleaning liquids can damage components. So, choose the detergent wisely
- In most cases, water works just as well
The cleaning of electronic circuits and printed circuit boards requires experience, knowledge, and unique electronic cleaners. Before you execute the process, keep that in mind.
