Answer / k. pratap
In 2 tier architecture we have only two tiers: client and
server. Depends on the application consistency we called
this 2 tier architecture as thin client-fat server
architecture or fat client-thin server architecture. In the
first one most of the business logic will be residing on
the server side, where as in the second one most of the
business logic will be residing on the client side.
In 3 tier or n tier architecture we will maintain one
seperate tier for this business logic. we will call that as
application server. This will act as the mediator for
converting the client requests into the database
understadable formats and it retrieves the data according
to the command given by the client and it will again
convert those results in the client understadable formats
and displayes in the internet explores pages.
