A GPIO port is a group of GPIO pins (often 8 pins, but it may be less) arranged in a group and controlled as a group. GPIO abilities may include: [2] GPIO pins can be configured to be input or output; GPIO pins can be enabled/disabled; Input values are readable (usually high or low) Output values are writable/readable
The Video Graphics Array (VGA) connector is a standard connector used for computer video output. Originating with the 1987 IBM PS/2 and its VGA graphics system, the 15-pin connector went on to become ubiquitous on PCs, [1] as well as many monitors, projectors and HD television sets.
Examples of computer connector sockets on various laptops Ports on the back of the Apple Mac Mini (2005) A computer port is a hardware piece on a computer where an electrical connector can be plugged to link the device to external devices, such as another computer, a peripheral device or network equipment.

Memory-mapped I/O is preferred in IA-32 and x86-64 based architectures because the instructions that perform port-based I/O are limited to one register: EAX, AX, and AL are the only registers that data can be moved into or out of, and either a byte-sized immediate value in the instruction or a value in register DX determines which port is the source or destination port of the transfer.

The 8255 has 24 input/output pins. [10] These are divided into three 8-bit ports (A, B, C). [11] Port A and port B can be used as 8-bit input/output ports. Port C can be used as an 8-bit input/output port or as two 4-bit input/output ports or to produce handshake signals for ports A and B. The three ports are further grouped as follows:
