Study Notes
Definition and Function
- An output device is any peripheral that conveys information from a computer to the user.
- This information can take various forms, including text, images, audio, and video.
- Output devices translate the computer's processed data into a human-readable or usable format.
Types of Output Devices
-
Visual Output Devices: These devices display information visually.
- Monitors (or Displays): Common visual output devices displaying text, graphics, and video. Technologies like LCD, LED, and OLED are used. Resolution, refresh rate, and size are crucial characteristics.
- Projectors: Display computer images onto larger screens. Useful for presentations and large group viewing. Brightness, resolution, and contrast ratio are important considerations.
- Printers: Produce hard copies of documents, images, or other output. Types include inkjet, laser, and 3D printers. Print speed, resolution (DPI), and color quality vary.
-
Audio Output Devices: These devices provide sound.
- Speakers/Headphones: Enable users to hear audio from a computer (music, movies, alerts). Sound quality (fidelity), volume, and clarity vary.
Other Output Devices
-
Physical output devices: Devices producing tangible output.
- 3D Printers: Create physical models or objects from digital designs. Resolution, material options, and print speed are key factors.
- Plotters: Used for large-scale drawings and maps. Resolution, print size, and accuracy are important.
- Braille Displays: Output information in tactile Braille for visually impaired users.
Key Characteristics of Output Devices
- Speed: How quickly the device produces the output.
- Resolution: Clarity and detail of the output (pixels or DPI), crucial for visual output.
- Quality: Level of detail and fidelity of the output (color accuracy, sound quality).
- Connectivity: How the device connects to the computer (USB, HDMI, Bluetooth).
- Cost: Price of the output device.
Common Examples
- Monitor (LCD, LED, OLED): Displays text, images, and videos.
- Printer (Inkjet, Laser): Produces hard copies.
- Speakers: Play audio.
- Headphones: Personal audio experience.
Factors to Consider When Choosing an Output Device
- Task: Intended use (gaming, presentations, printing).
- Budget: Price range.
- Size and portability: For monitors and portable speakers.
- Resolution and quality: Desired quality for the given task.
- Features and connectivity: Needed features and compatibility.
- Environmental considerations: Energy efficiency.
