Computer Interfacing

Three components are required in order to produce a computer interface: Computer Interface Peripheral The computer allows information to flow back and forth between the computer and peripherals through the parallel port. The interface such as printer consists of electronic components that require commands to be operated. The peripherals allow commands to be sent to the interface, and one most common example is parallel port. The main peripheral that can be used in a computer …

…is helpful visuals that can allow the user to determine the progress of the operation. In summary, this software is necessary for control over the interface. Parallel port can be used to interface: LEDs - turn on or off, display a pattern Motors - starting or stopping, controlling further operations Sensory devices - such as miniature robots Printer - executing printing instructions Scanner - executing scanning instructions Circuits - small circuits, inputs can be controlled
