Study Notes
ICT Input Devices: Keyboard Technology
- Keyboards are the most common input devices for text entry.
- Mechanical keyboards use physical keys, typically employing mechanical switches.
- These switches offer tactile feedback and distinct actuation points, contributing to a better typing experience.
- Membranes keyboards are frequently used in laptops.
- These keyboards are more affordable and compact.
- Modern keyboards use variations such as ergonomic layout for reduced strain, and multi-function keys for advanced commands.
- Keyboards often incorporate anti-ghosting technology to ensure multiple keys are properly registered simultaneously.
- Key scan technology and internal circuitry translate keystrokes into digital signals for processing.
- Different layouts cater to varying language and cultural needs.
- Keyboards vary in layouts across languages, with differing key positions and combinations for specific needs.
ICT Input Devices: Mouse Types and Functions
- A mouse is a pointing device that controls the cursor on a screen, directing user interaction.
- Optical mice track movement by using a light source and sensors, responding to the reflection of light off surfaces.
- Mechanical mice use a ball mechanism for tracking on a surface, often producing more noise and slower response, albeit cheaper.
- Laser mice are high precision, more accurately tracking movement on various surfaces and with a greater field of view.
- Touchpads are small, flat rectangular surfaces incorporated into laptops or tablets, allowing users to interact with devices using finger gestures.
- Touchscreens directly accept input via touch, common in mobile devices and interactive displays.
- Wireless mice communicate with the computer wirelessly, usually over radio frequencies or Bluetooth.
- Ergonomic mice are designed to promote comfortable positioning and reduce strain during prolonged usage, offering different shapes and grips.
ICT Input Devices: Scanners and Imaging Devices
- Scanners convert images or printed documents into digital files readable by computers.
- Flatbed scanners are widespread due to their convenience and ability to scan documents of various sizes.
- Handheld scanners have a smaller form factor and allow easy scanning of documents or materials of differing sizes.
- 3D scanners capture data from different angles, creating detailed 3D models of objects.
- Digital cameras are used for still image capture and are versatile for use in other situations as well.
- Webcams, used for video capture, are less expensive than high end cameras and provide affordable video options.
- Optical character recognition (OCR) software can convert scanned documents into editable text.
- Magnetic resonance imaging (MRI) uses powerful magnetic fields to produce detailed medical images of the inside of the body.
