What is the difference between 2-Tier architecture and
3-Tier architecture

Answer Posted / ravi148

hi
2-tier - also called client/server applications which
consist of two separate applications, one server
application (typically a database server like Oracle, MSSQL
or any other standalone database) and a client application.
suppose you want to have many different clients for front-
end would be unwise to copy all the business logic (all the
rules of your application) to each client app.,. so its
better to create a middle layer containing the business
logic, and then let the clients talk with this middle
layer. Thus the clients can relatively easily be changed
for other types of clients, without need for remembering
how was the business logic put together.

3-tier architeture where one tier is the backend database
engine, one is the front end client and one is just in
between them, also named the application server or business
logic node.
its uses mainly Load balancing and Fault tolerance.
