The devices used to interact with a computer system, including keyboards, mice, printers, and displays.
Input Devices: These are devices used to provide input to a computer system. Examples include keyboards, mice, touchpads, scanners, digital cameras, microphones, and more.
Output Devices: These are devices used to display or output data from a computer system. Examples include monitors, printers, speakers, projectors, and more.
Interfaces: These are the connectors and protocols used to connect various input and output devices to a computer system. Examples include USB, HDMI, Bluetooth, analog audio inputs, and more.
Drivers: These are software programs that facilitate communication between the computer system and the input or output device. They translate the device's language into a language the computer system can understand and process.
Data Transfer Rates: These are the speeds at which data can be transferred between the input/output devices and the computer system. Factors that affect the transfer rate include the interface, drivers, and the device's capabilities.
Human-Computer Interaction (HCI): This is the study of how people interact with technology, including input and output devices. It encompasses research in areas such as user interface design, usability testing, and information architecture.
Device Resolution: This is the level of detail and clarity that an input or output device can provide. For example, monitor resolution is measured in pixels, while scanner resolution is measured in dots per inch.
Latency: This is the time delay between when an input is detected and when the output is generated. High latency can result in frustrating delays, whereas low latency can provide a more seamless user experience.
Signal Processing: This refers to the way in which the input and output signals are processed as they move through the system. Examples include analog-to-digital conversion, pulse-shaping, and signal amplification.
Power Consumption: This is the amount of power required to run the input or output device, which can affect the overall power consumption of the computer system as a whole. Lower power consumption can result in longer battery life and reduced energy costs.
Keyboard: Allows the user to input letters, numbers and symbols into the computer by pressing specific keys.
Mouse: A pointing device that allows the user to select and move objects on the computer screen.
Touchpad: A pointing device similar to a mouse but is a built-in device on laptops.
Joystick: Input device commonly used for gaming, it allows the user to control the movements of characters on the screen.
Scanner: A device that can digitize images and documents and convert them into computer-readable formats.
Webcam: A device capable of capturing video and audio to record or stream content to the computer.
Microphone: An input device capable of recording sound or voice to the computer.
Monitor: Display for outputting visuals and text from the computer.
Printer: A device that reproduces text and images on paper or other media.
Projector: Projects visuals from the computer onto a large screen or wall.
Speakers: Output device for sound.
Headphones: Personal output device for sound.
Plotter: A device used to produce high-quality, large-format output such as graphics and maps.
Braille display: Converts text on the computer screen to braille for visually impaired individuals.
