an electronic tool that allows information to be input- process , and output is?
Answers
Answer:
A computer is a machine that can be programmed to accept data (input), process it into useful information (output), and store it away (in a secondary storage device) for safekeeping or later reuse.
Answer:
In computing, an input device is the piece of equipment used to provide data and control signals to the information processing system, such as a computer or information appliance. Examples of input device include keyboards, mouse, scanners, cameras, joysticks, and microphones.
Input devices can be categorized based on the following factors:
modality of input (e.g., mechanical motion, audio, visual, etc.)
whether input is discrete (e.g., pressing of key) or continuous (e.g., a mouse's position, though digitized into the discrete quantity, is fast enough to be considered continuous)
number of degrees of freedom involved (e.g., two-dimensional traditional mice, or three-dimensional navigators designed for the CAD applications)
An output device any piece of computer hardware equipment which converts information into a human-perceptible form or, historically, into the physical machine-readable form for use with other non-computerized equipments. It can be text, graphics, tactile, audio, or video. Examples include monitors, printer, speaker, headphone, projector, GPS devices, optical mark readers, and braille readers.
In an industrial setting, output devices also include "printers" for paper tapes and punched cards, especially where tape or cards are subsequently used to control industrial equipments, such as an industrial loom with electrical robotics which is not fully computerized form.
