There was a substantial volume of controversy when IBM included a printer port on the PC that didn't Adhere to the market-conventional Centronics style, and it absolutely was rumored that this had been completed to prevent consumers from using non-Epson/IBM printers with their equipment (plugging a Centronics printer into an IBM Computer system could problems the printer, the parallel port, or each).
^ Often the tracks have been also referred as cylinders, and that is technically suitable and analogous to harddrive cylinders. A single floppy disk monitor equaled one cylinder, having said that with double-sided floppies, only the first facet's cylinder quantities were being similar to the keep track of numbers; on the second facet, the cylinders one-40 corresponded to tracks forty one-80 of your formatted floppy.
