A "diode" will allow current to pass thru it in only one direction, provided you don't overload it.
A method for the CPU to communicate with the device, Software to instruct and control the device, and Electricity to power the device.
a mouse
The device that allows u 2 hear the CD and codes is called a laser head.
There is no device that allows a computer to work in a different country you have to change the settings in the computer for it to work in a different country.
If you have the skills to create your own USB device, you should have the skills necessary to write a device driver for it.
diode
Diode in simple terms is a "One Way" Device, i,e it allows current to flow thru in one direction only.Diodes are the most indispensable part in the electronic/electric World.
The kind of material used in a device depends on its requirements and functions. Semiconductors are used where we need moderate conductivity, conductors are used where we need very high conductivity. Junction diodes(a semiconductor device) allows electricity to pass in one direction and can be used as rectifier. Conductors can't do this. Transistors and LED are other applications of semiconductor. Note that generally devices are made of both conductors and semiconductors.
A diode is a semiconductor device that allows current to flow in one direction only, while an LED (Light Emitting Diode) is a type of diode that emits light when current passes through it. In simpler terms, a diode controls the flow of electricity, while an LED produces light.
compass
A diode is a semiconductor device that allows current to flow in only one direction. Although there may be several reasons why there is a diode on a calculator PC board, a common reason would be to protect the device from a battery inserted in the wrong direction (if battery powered) or if an AC adapter is used, to make AC into DC current.
A light-driven semiconductor device that prevents current flow in either direction until it receives a signal.
A device that changes the direction of the current is called a "switch" or a "reversing switch." This device allows for the current to flow in different directions as needed.
N is the type of semiconductor, MOS refers to Metal Oxide Semiconductor device.
A momentary 3-way switch in an electrical circuit is used to control the flow of electricity to a device or light fixture. It allows the user to turn the device on or off by pressing the switch momentarily in either direction.
LED = Light-Emitting Diode This is a semiconductor diode that emits light when an electric current is applied in the forward direction of the device.
N is the type of semiconductor, MOS refers to Metal Oxide Semiconductor device.
