Input / Output Ports \(I/O Ports\) of Input pin A logic one (1) is applied to a bit of the P register. The output FE transistor is turned off and the appropriate pin remains connected to the power supply voltage over a pull-up retor of high sis resistance. Logic state . COM1 is the bottom connector; COM2 is on the top. The integrated parallel port uses a pin D-subminiature connector on the system's back panel. This I/O port sends data in parallel format (where eight data bits, or one byte, are sent simultaneously over eight separate lines in a single cable). Computer Input/Output Ports and Interfaces. Terms and abbreviations: port an electrical connection using multiple wires to send data typically between a computer and a device. interface a standardized method of communicating data typically between a computer and a device. bit a single binary.
