[05:22:10] GPIO is an acroynym that stands for General Purpose Input/ Output.

GPIOs are often placed into groups of 8 pins. In some cases, GPIOs may use Direct Memory Access in order to move large amounts of data in an efficient manner.

[05:31:29] PCI stands for Peripheral Component Interconnect and is a commonly used interface. Typical PCI cards used in PCs include: sound cards, USB/Serial ports, and other such hardware. The PCI Local Bus (often referred to as PCI), is used for attaching hardware devices in a computer such as a planar device (an Integrated Circuit that is mounted onto the motherboard), or an expansion card.
