Clarification isn't something you "know". You seek, obtain, need, or
get clarification, not know it.

Having an address which is accessable through an instruction to read or
write system RAM.

Having an I/O location assigned, accessable though an I/O instruction.
> 3. what is memory mapped IO ?
I/O registers that are accessed via normal memory instructions. Some
processors have no separate I/O instructions, so all I/O is memory mapped.
> 4. what is IO mapped memory?
Memory accessable by I/O instructions? One example is an external FIFO
that you write one byte at a time. Another would be external EEPROM
that are accessed serially and used in small systems.
