Kerning - adjustment of the space between two specific letters.

I am just wondering what computer subsystem is responsible for font kerning. Is it font engine  ? Or it is quality of specific font  ?

If it is quality of specific font can you please give me the names of most known fonts which uses a kerning.

Thanks in advance.
