Wired and Wireless Port CommunicationAbstractIn today’s society, technology influences our daily lives in a variety of ways. We are constantlydependent on the use of technology to achieve everyday tasks. Computer technology, forinstance, has become an integral part of our task oriented society. How is the computer able toperform and achieve such a wide variety of tasks? The keyword is communication (with wiredor wireless). A computer can be considered as a device that provides communication betweensystem software and hardware. It also communicates with wired or wireless external deviceswith the help of standard communication ports such as parallel, serial and Universal Serial Bus(USB) ports. The external device could be in the form of a printer, scanner, embedded systemwith micro-controller, or a custom designed system, etc. This approach, whereby a computercommunicates with wired or wireless external device through a standard communication port,has provided the vital transformational change in today’s technology.The concepts of parallel, serial and USB ports are explored, in depth, as part of the trend incomputer communication technology. In particular, emphasis is placed on the discussion of howto communicate and interface, with wired or wireless, between user-designed software and acustom designed system which may incorporate an embedded micro-controller. In the past,parallel and serial ports were the standard communication interface available on most personal aswell as industrial computers. However, their limitation of the speed of communication andinflexibility in communicating with multiple devices prompted the introduction of USB interfaceport. The modern personal computers have mostly eliminated the parallel and serial ports, infavor of more flexible (and more complex) USB port. However, the serial port to a greater extentand the parallel port to a lesser extent, continue to enjoy significant application in industrial andembedded computer systems, in situations where low cost, low speed and single devicecommunication is needed.
