Memory , I/O, Memory-I/O and I/O-Memory Mapping

Hi,

What is the actual difference between the following :
1) Memory Mapped
2) I/O Mapped
3) Memory Mapped I/O
4) I/O Mapped Memory

Kindly tell me their actual definitions/meanings .
Further, Let me know some best conditions whereit should be used and
other scenarios where it should not be used.

Need some clarifications / links / docs.

Thx in advans,
Karthik Balaguru
