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.

Answer / sunil reddy
2 tier architecture is nothing but client and server
Means It consits of client(Presentation layer) and server
(may be database)
Client gives the requests through the browser for HTMl
pages stored in remoting machine(Server).The server locates
this files and passes to the Client
Only presentation layer and database server exits
Request are in the form of Http or FTP
Most of the actions done on the client side so client is
thick and server is thin
Web application consits of Presentation layer( client or
browser)Business process and database layer
As i mentioned earlier
Presentaion layer is useful for to submit the requests in
HTTP form
Web server recieves the Request in HTTP form and sends to
application server. Application server process the Request
and gets the information from the database and sends back
to Web server. WEb server sends the recived data in the
form of HTML to the client.
Most of the action done on the server side
so client is thin
Presentaion laye<-->web server<-->application server<-->data

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
architure

Answer / mallikarjun
In 2 tier applications client requests the server
directly,there is no intermediate layer between them.
In 3 tier aplications there is middleware (Is nothing but a
collection of diff. softwares),first client request is
received by middleware & then it passed to server,after
that server give response.

Answer / gaumzi
In Two Tier application if client hits the server then in
Server the request goes, verified by the Databse or
buisness logic as application layer and Database are
connected in parallel and server replies to the client.
In Three Tier architecture when client hits the server then
in server there is some temporary database connected in
parallel with Application layer and after that the main
Database server is connected with that server in series,
after verification from the first database server
(Temporary) the data finally goes to second Database server
(Final repository).
This is how the architecture can be increased to n-tier.
