Computer devices such as mice, printers, scanners and speakers are known as peripheral hardware. These peripherals are further split into two categories, input devices and output devices.

Revise the ways that informational technology controls the various systems in our homes. Learn the technology that requires input and output devices.

Output devices include speakers, monitors and printers. This explanation includes how input devices are converted into binary code, and how wireless devices like tablets have both inputs and outputs.

In prior Java 101 articles, I referred to the concepts of redirection, standard input device, and standard output device. To demonstrate inputting data, several examples called System.in.read().

We generally think of plugging new input/output devices into a computer and turning it on to get something new. But with this model, the previously stored data is changed by the new parts, too.
