KeyboardsThe ideal input devices that is used to input texts,numbers and instructions (eg CTRL+V) into thecomputerMost keyboards It is mostly used on phones, ipads, petrolstations, ATMs, Interactive boards and other payment methods . "An input device is a hardware device that is used to provide input (data / instructions) to a computer so that it can be processed". Besides the widely used input devices like keyboard & Mice there are other different input devices that perform various input operations like a scanner scan images Input Devices The devices which are used to give data and instructions to the computer are called Input Devices. Various types of input devices can be used with the computer depending upon the type of data you want to enter in the computer, e.g., keyboard, mouse, joystick, light pen, etc. Input devices have a history as long as computers themselves. Perhaps the first input device was the simple electronic switch ( similar to a light switch ) which turned bits on or off. As computers evolved throughout the late 20th century, computers became more and more interactive. Input and Output Devices are required for users to communicate with the computer.Input devices bring information INTO the computer and output Keyboard is most common input device is used today. The data and instructions are input by typing on the keyboard. The message typed on the An input device is a piece of hardware used to provide data to a computer used for interaction and control. It allows input of raw data to the computer for processing. Read more of the theory on input devices or sign up to download our GCSE Computer Science resources today. Interactive input devices are those that give the user feedback as they are used to feed in data. An example is a touchscreen, which doubles up Input devices include the keyboard, pointing devices (such as mouses), scanners and reading devices, digital cameras, audio and video input devices What is an input device? Input devices are used to provide data and control signals to a computer. Input devices allow us to enter raw data for processing. Benefits of interactive whiteboards. Large display allowing multiple people to view at once. Interactivity helps learning and presentations. 13. API - Input Devices¶. These input device component interfaces have been provided for simple use of everyday components. Represents a generic input device with typical on/off behaviour. This class extends InputDevice with This method is primarily intended for interactive use at the command line. 4 Logical Classification of Input Devices Logical input device refers to input devices classified according to data type. LOCATOR - specifies one coordinate position STROKE - specifies a set of coordinate positions STRING - specifies text input VALUATOR - specifies a scalar value CHOICE An input device is a hardware device, often a peripheral device, which is used as part of a computer system. Input devices allow a computer system to receive data from the real world. For instance a microphone can be used to input audio data in to a computer system. The HTML input element is used to create interactive controls for web-based forms in order to accept data from the user; a wide variety of types of input data and control widgets are available, depending on the device and user agent.
