To operate expansion cards, “resources” required for operation must be reserved.
The floppy disk drive or hard disk drive inside the PC uses predetermined paths specific to
those devices when transferring data with the CPU and memory.
These paths include I/O port addresses, DMA channels, and interrupt levels (IRQ), which
are generally called “resources.”
Expansion cards for PCI bus can be installed in the PC.
Because expansion cards for PCI bus are “Plug & Play supporting cards”, the resources
are set automatically when installing the card.
