hi i m swapnil
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 / frso
In Two-Tier Architecture we have just two layers
1. GUI/ intrface / presentation layar
2. Database layer (where we store/retrieve our data)
Basically this architecture is followed in client/server
applications where database and application resides in the
same machine or database may in other machine conected
thtough network.
Three-Tire Architecture:
In three tier architecture we can find three layers names:
1. Presentation Layer
2. Busness Layer/ Mid Layer
3. Database Layer.
Presentation Layer: GUI/Interface , where a user view or
enters the data.
Business Layer: where business login and rules are execute
and can accommodate hundreds of users.
Database Layer: Data access layer takes care of connection
between the appication and storing the data as a warehouse.
This is very important layer in any architecture 'coz
finally all data comes to it and maintaining such a huge
amount of data is taken care by this layer avoiding
concurrency and maintaining scalibility, durability to the
application.

Answer / mitesh pandere
two tier achitecture is use for implement web based
application in which:
application logic implemented on pc's or client with
interfaces.application logic exicuted on pc not on the
server.database store on other server. one of the main
dissadvatage of this , when new updates release you have to
apply updates to each individual pc. think about network
where thousands of pc's connected, it's time consuming
process to apply updates to each pc on network.
three tier architecture is archetecture use for web based
application in which it consist of :
1)presentation layer :implemented on client.
This is topmost layer of 3 tier it . you can think it as
GUI gets input form user send it to application logic,
and show the result in sutable format.
2)applicaton logic layer or server:
this layer cordinate the application , process ,
comands,makes logical decisions, calculatons.
search contains from databases
3)database server:
this generally stores data in tabaular format.
generally database server RDBMS. the information you ,
will get after proceesing data from database server .

Answer / sethu
Two tier architecture :
Client server application. Client acts as Front End
and Server acts as Back end (databases).
Here where client make a request to the server where
the query evaluated in the server and returns the request
given by client .where here all the query evaluated in the
server side .
Three tier Architecture :
Three tier architecture means N tier architecture
1. Presentation Layer
2. Business Layer/ Middle Layer(tier)
3. Database Layer.
where here client make a request to server through
presentation layer to get some data the query is evaluated
in business layer and the data is retrieved from the
database layer(all the complicated work done in middle layer
) . Database layer is responsible for all the connections
between the server .so the accessing through database make
easier through 3tier architecture

Answer / asadul
The two-tier architecture is like client server application. The direct communication takes place between client and server. There is no intermediate between client and server. The two tiers of two-tier architecture is
Database (Data tier)
Client Application (Client tier)
Three tier architecture having three layers. They are
Client layer
Business layer
Data layer

Answer / kartheek yakkati
2 tier architecture :- A 2tier architecture have two
layers nothing but a Client server architecture.
3 tier architecture :- A 3 tier architecture have 3 layers
they are
1.Presentation layer : Its a front end which is implemented
on client.It is the top most layer of all the 3 layers.
2.Aplication logic layer : It is the layer in which all the
application logic is implemented.Every task will be
executed here,data required for the processes is retrieved
from the dedicated database servers which can be considered
as the third layer,and the results of all the processes
will be shown in the GUI whic is the top most layer.
3.Database layer : It is the last layer of the 3 tier
architecture,in this layer all the database will be stored
and retrieved by the application logic layer.In one term we
can say it as the "Storage layer".

1.)Two tier Architecture:
Definition: A Two tier architecture is an architecture which
contains two tiers.
Examples: Two wheelers like Bikes,Cycles etc...
Explanation: Here the Bikes and Cycles are having two tiers
namely,
a.)front tier-1 and
b.)back tier-1
Finally, Totally 1+1==>2 tiers.
So it contains only two tiers.
And hence it is also named as two tier architecture.
2.)Three tier Architecture:
A three tier architecture is an architecture which contains
three tiers.
Examples:Three wheelers like Ordinary Auto,Share Auto, try
Cycle etc...
Explanation: Here the Ordinary Auto,Share Auto and try Cycle
are having three tiers namely,
a.)One front tier and
b.)Two back tier
Finally, Totally 1+2==>3 tiers.
So it contains only three tiers.
And hence it is also named as three tier architecture.
If you still having any doubt then, go to www.google.com and
search Bike picture,BiCycle picture==>for Two tier And
then,Ordinary Auto picture,Share Auto picture,try Cycle
picture==>for Three tier. Or else, You better contact to my
number in the below and ask it directly . I will explained
you...
