What is the definition of core I/O?
Wtat are the components in core I/O, like lan port, MP etc.

There is no rigorous definition as it means somewhat different things on different models. On some models there is literally a separate board labeled "Core I/O" so whatever is on that card is, by definition, Core I/O. In other cases, the core i/o functions are integrated with the systemboard. In general, it means those I/O capabilities/ports that are included with the base system as opposed to optional i/o boards.
