General guidance needed; 'terminfo' and other special class of commands

[Sabniveesu Shashank]

Hi!

Today I came across some discussion to discover 'terminfo'. After a few
attempts I see terminfo is not a command yet a man page exists for it. This
raised a few questions:

1) What class does this 'terminfo' belong to and how many such exist?
2) Are they bash-specific or GNU-specific or what at all is their scope?
3) Are they called 'classes' or is there a term for them?
4) Is there a definitive place I can learn about them?

Thanks
