Answer Posted / suvendu dalai
Two-tier architecture is a client/server architecture ,
where a request to do some task is sent to the server and
the server responds by performing the task.
where as a three-tier or a multi tier architecture has
client, server and database. Where the client request is
sent to the server and the server in turn sends the request
to the database. The database sends back the
information/data required to the server which inturn sends
it to the client.
In other word you can say that in 3-tier architechure
business logic,databases & presentation are maintained in
different files whereas in 2-tier architechure business
logic &databases are maintained in same layer or file
3-tier architechure in other word u can say fallows MVC
