I/O adapter
An adapter that converts between the timing and protocol requirements of a system's memory bus and those of an I/O interconnect or network.
In the context of storage subsystems, I/O adapters are contrasted with embedded storage controllers, that not only adapt between buses and interconnects, but also perform transformations such as device fan-out, data caching, and RAID. Host bus adapters (HBAs) and Ethernet NICs are types of I/O adapters.
