this is done by some address reference and some service.
example: in your college and in office you are developing application in one system and your database server is on other system. they are communicating using connection string.
here 2 physical system
so its 2 tier.
like this you can separate your all layers .
for this you can use webservice ,wcf etc...

As u told in tier the components are physically separated into multiple machines, ok I am agree then how they are communicating with each other

It is a confusing question for beginners. A few think that both are the same. But they are not the same. Tier represents multiple hardware boxes. In other words the components are physically separated into multiple machines. But in the case of layers all components are in the same system.
