  port (computing)
In computing, a socket that enables a computer processor to communicate with an external device.
It may be an input port (such as a joystick port), or an output port (such as a printer port), or both (an i/o port).
Microcomputers may provide ports for cartridges, televisions and/or monitors, printers, and modems, and sometimes for hard disks and musical instruments (MIDI, the musical-instrument digital interface).

 PC World - Mobile Computing: Port Replicators
Though there are variations, a typical port replicator is a device containing common computer ports such as parallel, serial, PS/2, and USB.
You connect your peripherals to the port replicator, rather than to the ports on your notebook, then connect your notebook to the port replicator.
For instance, my Dell notebook (which is the computer I use daily) hooks up to a multifunction printer, a four-port USB hub, a back-up hard drive, an external keyboard, an external trackball, and a flash memory card reader.

  Utility Computing: Any port in a storm? | On-Demand, Grid & Utility Computing News   (Site not responding. Last check: 2007-10-30)
Given that Utility Computing is relatively new, there is ample room for dispute between suppliers eager to push the advantages of Utility Computing, and customers who may not be entirely sure what they are buying.
Without necessarily being able to rely on empirical evidence of successful utility computing transactions over the years, many customers may find themselves simply holding their breath to see whether the model works as promised.
In a Utility Computing arrangement, as in more conventional outsourcing models, it is important to ensure that, after the termination of the agreement, the customer is able to recoup its assets that the supplier used during the project.

 Net Optics 10/100BaseT Port Aggregator Tap | Tapping the Network Feed | Mar 18, 2004 | Network Computing
The Port Aggregator hardware includes dual external power supplies, two 10/100 Ethernet ports, one 10/100 monitor port and 2 MB of memory--1 MB each for A and B. The Port Aggregator passes frames transparently, regardless of whether it's powered, though the monitor port will pass frames only when turned on.
The Port Aggregator passed all frames at 100 percent utilization and with less than 2 microseconds of latency--hardly enough to matter.
Using SmartWindows, I tested the monitoring port's capabilities by connecting Port 1 of the SMB 600 to the Port Aggregator's Port A, Port 2 of the SMB 600 to Port B and Port 3 of the SMB 600 to the monitoring port.

 Jan Axelson: Parallel Port Complete a jpoc computing book review
The author covers the port from the nitty gritty of designing and building custom hardware to connect to the parallel port to the higher level protocols such as the IEEE standard for daisy chain negotiation on the port.
Many systems now include parallel ports that are register compatible with the PC parallel port from a programming point of view.
More that that, the protocols that operate between the computer and the peripheral are standard and so something like the daisy chain protocol is relevant to any architecture that wants to use it.
