Give details about An N-Tier Application program.
An N-tier Application program is one that is distributed among three or more separate computers in a distributed network.
N-tier architecture would involve dividing an application into three different tiers. These would be the
1)logic tier The application logic tier is where all the “thinking” happens, and it knows what is allowed by your application and what is possible, and it makes other decisions. This logic tier is also the one that writes and reads data into the data tier.
2)presentation tier The presentation tier is the user interface. This is what the software user sees and interacts with. This is where they enter the needed information.
3)Data tier The data tier is where all the data used in your application are stored.
