I have some guesses about some of them, but am not certain.  Sorry if I missed the definitions, but I cannot find them in the manual.  What do each of these acronyms mean?

 

FIO =  Flexable Input or Output.  This pin can be configured for an analog input, a digital input, or a digital output.

EIO = ?

CIO = ?

The names are arbitrary.  You can also call them DIO0-DIO19.

The differences:

 

FIO & EIO can be set to analog or digital.  CIO are digital only.

 

FIO are on the built-in screw-terminals.  EIO & CIO are on the DB15.

 

FIO have ~550 ohms source impedance.  EIO & CIO have ~180 ohms of source impedance.

Thank you for the link to the discussion.  I see there they say,

 

The origin of the names is FIO=Flexible, EIO=Expansion, CIO=Control, and MIO=Multiplexing, but those names don't always have true meaning.

 

Even if the actual usage of the channels can change, it really helped me to sort them out when I can remember a meaning to the letters.
