Communication is an inherent part of computers, and various protocols and methodologies have been used to facilitate this communication. Low-speed serial interfaces may not be as smooth as high-performance PCI Express, but large numbers of serial ports tend to be a requirement for many embedded microcontrollers to interface with digital sensors and control systems.
