Input Devices

The graphic input devices subsystem includes the keyboard/sound, mouse, tablet, dials, and lighted programmable-function keys (LPFK) devices. These devices provide operator input primarily to graphic applications. However, the keyboard can provide system input by means of the console.

The graphical input device (GID) enables model users to. see, at a glance, the shape of a graphical function. edit a graphical function from the Interface layer. restore a graphical function to its author-defined relationships. view an animation of the “Y” value of the graphical function during a simulation.

In computing, an input device is a peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or other information appliance. Examples of input devices include keyboards, mice, scanners, digital cameras and joysticks.

Language and memoryData and instructionsText and graphicsStorage and commandsFeedbackCorrect. These are the two categories of input. Data can be unprocessed text or numbers, images, etc.

An output device is any piece of computer hardware equipment which converts information into human readable form. Some of the output devices are Visual Display Units (VDU) i.e. a Monitor, Printer graphic Output devices, Plotters, Speakers etc.

Speakers receive information from computers (think smartphones, laptops, tablets, etc.) and are, therefore, output devices. This information is in the form of digital audio.

Keyboard and Mouse are input devices. Monitor, Speakers and Printer are output devices. Any device has to be connected to the CPU to receive or send information.

It does both send data and receive data, so it is an input/output device entirely.

According to the input signal from input devices the required data i.e. the output signal is send to the output devices. so hard disk is neither input and nor output device.
