How many types of mining pool are exist for bitcoin or litecoin?

[navidos]

I would like to know exactly how is the type of different Bitcoin or litecoin pool ?!

For example when you have P2POOL , it can be getwork or stratum but they are protocol.

In some pool like BTCGuild when you mine, the reward will be added instantly but in P2POOL takes time to see the reward in you wallet.

Please explain clearly .

Thanks
