Activating Virtual SmartDust Keyboards by Lance Winslow
SmartDust are tiny electronic particles which are connected together electronically using those nodes or motes. There should be away to sprinkle the use tiny SmartDust onto a surface and use the SmartDust as a virtual keyboard for data input into a computer. ... In this way you can type the data into the device without looking at the surface where the smart to dust is located, but rather at the input device. ... Such a system would allow you to input data into a very tiny device such as something the size of an iPod Nano with a one and one half inch LED screen, a wristwatch computer or PDA.

What are the Main Components of Any Computer, and Which are the Most Critical to Its Performance? by George Chamoun

Embedded DVR by Max Bellamy
In most surveillance operations using a DVR, the commonly used method is to link the DVR card to a computer containing the software. This has serious limitations in the event of a virus attack or power failure, because the surveillance system could be thrown off gear. ... Embedded DVRs also have remote storage facility meaning storage of information can be done at a location away from where the input device is located. ... If there is a problem with storage, a back up plan is activated where by the data is written onto CD disks.

History of the Computer: Handshaking, Part 1 of 2 by Tony Stockill
There is still information to be transferred to the I/O unit from the printer, for example a request for the next line of print, or an error message. So we use an OUTPUT cable and an INPUT cable. Apart from this, the printer is an Output Device. (We are talking here about the System Line... We observe a convention here, that data movement FROM the mainframe is considered to be OUTPUT, while data TO the mainframe is considered input. ... This convention is continued down the hierarchy, so that data from a disk drive to a controller is Input data, headed for the mainframe.
