Need explanation on 2 tier and 3 tier. Thank you

Hello all.

I'm new to forums so i've no idea where to post. But i think 2 tier and 3 tier is kindia in advance for java so I would like to ask someone to explain to me what's the difference between 2 tier and 3 tier java programming.

I've google what's the difference BUT i still dont understand this is what i think

"2 Tier"
Computer Control The Java Coding and OOP ( Am i right to say this or I'm wrong? This is what i think please correct me thank you all )

"3 Tier"
Computer act as a server which has a database and it can be control the java coding and OOP things BUT other device such as laptop on the another end which can access the server and edit the database record or maybe end device like iPhone can access and edit the database? ( this is what i think i've no idea am i right or wrong so please correct me

Thank you all !! Sorry for my bad english.

Sorry about that

You could have looked this up on wikipedia you know.

And it has noting to do with OOP. It's an architectural thing.

2 tier - client talks to database server.
3 tier - user interface talks to middelware (business) layer which talks to the database. Though this can be multi tier.

Hmm so do anyone have any recommend for me to learn 3 tier ?? Any website that teach? Thanks alot in advance.

No idea I'm afraid.
Start with the wiki article on it.
I think it might be multi tier.

So anybody got any recommendation to learn 3 tiers Java programming
