Explain isolated I/O scheme.

In I/O mapped I/O scheme the addresses allocated to memory locations can also be assigned to I/O devices. Because the same address may be assigned to an I/O device or a memory location, the microprocessor should issue a signal to distinguish when the address on the address bus is for an I/O device or a memory location.
