What are memory mapped I/O and isolated I/O? What are differences between memory mapped I/O and isolated I/O?

Memory Mapped I/O and Isolated I/O are two methods of performing input-output operations between CPU and installed peripherals in the system.  Memory Mapped I/O: Memory mapped I/O uses the same address bus to connect both primary memory and memory of hardware devices (registers). Memory and registers of I/O devices gets assigned values, thus when CPU …
