An input method is typically a term used to describe the entirety of the
program(s) that do input for a specific language. So you can have a Korean
input method, a Japanese input method, et cetera.
A conversion engine is the inside of an input method, specifically the part
that takes your written text, ro-maji to kana to kanji + kana in Japanese
case, ro-maji to jamo to hangul in Korean's case, ro-maji to pinyin to hanzi
in Chinese case, and converts it in the probable characters that you wanted,
depending on context.
I think input module is a hook-in module for a specific input method.

It's essentially part of the 'workflow' for any input method. You have the raw
Every time the input matches a kana it gets transliterated/replaced, so you
pressing space (or some other trigger key) will switch to the conversion mode,

Those are read as: ro-maji, kana, and I am not sure what AZIK is.
In general people use the ro-maji one if they have, say, an US (international)
keyboard, the kana if they have a keyboard with keys (sub-)marked with
hiragana symbols, and AZIK I would not know.
Of course, this is all based upon my own experiences and reading into the
subject at hand.
Hope this helps,
