There are several input devices for the differently abled. There are the numeric keypads, bar-code readers, digitizing tablets, and light pens to name a few.
It is none of your business
RAM (Random Access Memory) is a storage device
Dwarves aren't physically challenged, although that doesn't mean that some can be. Dwarves are just a normal person that have a gene defect that limits them to a short growth. It is a recessive gene.
In Light Emitting Diodes when electron jumps from one state to another state it emits some energy in the form of light. And the light will be different for different type of semi conductor materials used for making for it. So, in conclusion Light in LED is a result of output process.

No, a voice synthesizer is an output device. An input device is anything that accepts information, these include keyboards, mice, microphones, webcams, ect. An output device is something that gives you information, some examples of output devices are computer screens and speakers. Since a voice synthesizer uses the speakers it is an output device.
Generally yes, however some video cards also accept input from other devices.
An output interface is a device that show information or data from a computer. Some examples of output devices are printers and monitors.
Because they are too young physically challanged and mentally challenged or they are too old,
a keyboard can be an output device if it is designed to be so. example: 1: some keyboards for the blind have a row on the bottom of them that outputs what is on the screen in braille. 2: the logitech G15 has a LCD on it that outputs information.
In the strictest sense, no. It is an output device only. However, touch screens are input devices, but some would say this is just the touch panel mounted on top of the screen - so the screen is an output device while the touch panel is a separate input device. They are integrated into one unit but do have separate connection to the computer. Some would say its it one unit that does both input and output since the touch panel is integrated. The case could be made for either really, its just semantics anyway. Also, some monitors have USB hubs built in, but these really just bridge the USB device and the USB controller in the PC with no actual processing of data, so really shouldn't be considered an input device either.
Desktop are both, mean input and output, but in some times it is call out put device.
