An input device is any device that is used to provide data and control signals to an information processing system.
Examples:
* Keyboard * Mouse * Microphone * Web cam
An output device is any computer hardware equipment used to communicate the results of data processing carried out by a computer.
Examples:
* Monitor * Printer * Projectors * Speakers

∙ 14y agoAn input device is a piece of technology which allows information to be sent to a computer system so that it can process it in some way whereas an output device is a piece of technology that allows information to come out of a computer system.
The most common input devices are the computer keyboard and computer mouse.
The most common output devices are the VDU (Visual Display Unit: monitor) and the printer.

Difference between Input vs output?
An input device is something that enters anything into a secondary system that's following. A mouse is used to maneuver a UI A monitor is used to display the mouse and the UI Mouse being input Monitor being output If you have any specific devices just post them

How might knowing about the inputs and outputs and side effects or errors produced within a system or device help you fix the device?
The question seems to most clearly be rephrased as "How does a device's output depend on it's input, and how can I troubleshoot it?". As an EE, I can best answer from a generalized electronic approach. In general, electronic systems consist of an input, some "box", and an output. For the output to be correct, the "box" must know what the error is between it's input, and it's expected output. Though there are several methods, the most basic one is termed "negative feedback". The concept is simple. An input is applied, the "box" does it's thing, and supplies the output. But how does the "box" know it's "right"? In general, the box must react to it's input and quickly produce an output, but how? Using negative feedback means using a basic addition system where that system compares the input to the "box" to it's output. For a system to be stable (and the theory is beyond this question), this feedback consists of adding a negative version of the output back into, and added to the input. Any difference is the error and is used to modify the output. If this is hard to visualize, think of it like this: A camera sees a dark area and decides to flash a bright light. But it does not know how the light will reflect. So before the camera takes the picture, it measures how much light comes back and subtracts that from what it originally flashed. Now the subtraction of what it put out vs. what it sees (negative feedback) shows what the "error" or correction is required. Knowing the difference allows the rest of the processing know how it needs to adjust so that what "what went in" = "what needs to come out". Now, how to fix a device? Well, it might not be apparent, but this stabilizing system of negative feedback can make it very difficult to diagnose a device or system. Fundamentally, it gets in the way while you try to see what's wrong, It is there altering the behavior of the "box" as it is malfunctioning, trying to make things right. So the basic answer is that, in order to fix a device, you have to first know what the input and output characteristics are, WITHOUT feedback. Then, to SEE that characteristic, the feedback somehow, must be removed, or accounted for so that it's effect can be eliminated from the "output = input x something" characteristic. This can be a difficult job within any system. I myself have struggled in attempts to separate "what's wrong" with the correcting effects of feedback trying in vain, to fix an erroneous output. Knowing the fundamental device's input and output, plus the "correcting or side effects" of feedback, will help you fix the device.
What kind of bugs are you more likely to find with black box testing vs glass box testing?
You run Black box Test when you make integration test. This means you have input and output. You will therefore see that certain input may not match your expected output. To solve this use Boundary Value Analysis to find out what to values gives what result.
How many btu equal a 1 ton heat?
Heating units are not measured in tons as AC units are. Heating capacity is referred to in 1000`s of btu output per hour of operation. The ratio of input vs output = the efficiency rating, for example if your home furnace is rated at 100,000 btu per hour input and 80,000 btu per hour output . it is 80% efficient (when it was new). For AC 12.000 btu = 1 ton.
What is meant by the term touch computing?
The user interface aspects and workflow associated with using a touch screen as a primary input device, as opposed to a keyboard or mouse. Think iPad vs Windows.
What is the voltage gain of the FET amplifier?
It can be answered in two ways : 1. ratio of output & input voltages [Vout / Vin] i.e Drain voltage(Vds)/Source voltage(Vs). 2. multiplication of trans-conductance & drain resistance .
What are the advantages of voice recognition vs the keyboard?
Despite the development of alternative input devices, such as the mouse, touchscreen, pen devices, character recognition and voice recognition, the keyboard remains the most commonly used and most versatile device used for direct (human) input into computers. reference: http://en.wikipedia.org/wiki/Computer_keyboard
Can you use EU two pin adaptors in US 3 pin sockets?
It depends on the device. The US runs at half the voltage of Europe (110/120VAC vs 220/240 VAC). The device to be plugged in should state what input voltage range it can tolerate, or, in the case of a computer, will have a 110/220 switch on the back of the power supply.
What unit does a barograph measure in?
A barograph is a device that monitors pressure. It plots pressure vs time. Units can be kPa vs hr.
