A display device is the most common form of output device which presents output visually on computer screen. The output appears temporarily on the screen and can easily be altered or erased. With all-in-one PCs, notebook computers, hand held PCs and other devices; the term display screen is used for the display device.
Intelligent Input/Output (I2O) is a defunct computer input/output (I/O) specification.I2O was originally designed to make use of the Intel i960 microprocessor as the I/O offload engine, bringing channel I/O to the PC.
Devices for communication between computers, such as modems and network cards, typically perform both input and output operations. Any interaction with the system by an interactor is an input and the reaction the system responds is called the output. The designation of a device as either input or output depends on perspective.
In the original S/360 and S/370 architectures, each processor had its own set of I/O channels and addressed I/O devices with a 12-bit cuu address, containing a 4-bit channel number and an 8-bit unit (device) number to be sent on the channel bus in order to select the device; the operating system had to be configured to reflect the processor and cuu address for each device.
External Device Monitor (EDM). The device issuing the OSSD signals may have an EDM input. The EDM is used to verify that the controlled device (safety relay) did indeed open when the OSSD signals were dropped. The safety relay has normally closed contacts, which close when the relay is de-energized, thereby turning on the EDM input.
3. Control devices are always shown between L1 and the output device. Control devices may be connected either in series or in parallel with each other. 4. Devices which perform a STOP function are usually connected in series, while devices that perform a START function are connected in parallel. 5. Electrical devices are shown in their normal ...
The driverquery [4] command-line program generates lists of installed devices and drivers, similar to the Device Manager's output, which the user may view on-screen or redirect to a file. This is useful for note-taking and for reporting problems to remote third parties such as technical support personnel.
