Computers communicate with external devices (printer, keyboard, internet, etc) using ports.
The inport() and outport() functions in old compilers read from and write to a specific port, respectively.
By the way, Don't do that. Use the modern OS system functions to handle external devices. Unless you are writing a device driver, and working in Assembly language, you are making a mistake. (Oh, unless you are programming on an old 8086 or the like.)
