Input devices
Input devices are peripherals or tools that allow users to interact with a computer or electronic device by providing data or control signals
Mouse: The mouse is a pointing device that allows users to move a cursor on the screen by physically moving the mouse on a surface. It has 3 buttons for left and right clicks and a scroll wheel for navigation.
Touchpad: Commonly found on laptops, touchpads enable users to control the cursor by swiping or tapping on a touch-sensitive surface.
Touchscreen: Touchscreens allow users to interact directly with the display by touching it, making them prevalent in smartphones, tablets, and some computers.
Graphics Tablet: Graphics tablets are used by artists and designers for drawing and creating digital art. They consist of a flat surface and a stylus, providing precise control and pressure sensitivity.
Joystick: Joysticks are often used in gaming and flight simulation. They consist of a stick that can be moved in various directions to control on-screen movements.
Scanner/Barcode Reader: Scanners convert physical documents or images into digital formats, allowing them to be stored or manipulated on a computer.
Barcode scanners read barcodes on products, documents, or other items, translating the information into a digital format that can be processed by a computer.
Webcam: Webcams capture video and sometimes audio, enabling video conferencing, live streaming, and other multimedia applications.
Microphone: Microphones capture audio input, allowing users to record sound, make voice commands, or participate in voice and video calls.
Light Pen: Though less common today, a light pen is a stylus-like device that can detect light emitted by a computer screen, allowing users to interact with the display.
MICR stands for Magnetic Ink Character Recognition. It is a technology used for the recognition and processing of characters printed with a special type of ink that contains magnetic particles. MICR is commonly used in the banking industry for the encoding and reading of characters on the bottom of checks.
OMR stands for Optical Mark Recognition, a technology used to detect and interpret human-marked data on paper forms.
