Input and Output Devices

Now that we've talked about the origin of modern computers, we're going to talk about input/output devices. But first, what's the difference?

An input device allows you to enter information into a computer. It can also be described as,
"A peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or information appliance."~https://en.wikipedia.org/wiki/Input_device
The most fundamental pieces of information are keystrokes on a keyboard and clicks with a mouse. On the other hand, an output device converts input data into a form which can be seen, read, heard, or used as input for another device. Or it can be defined as,
"Any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) which converts the electronically generated information into human-readable form."~https://en.wikipedia.org/wiki/Output_device
