b.) Two tier and Three tier architecture

In a two tier architecture there is a data server and a client application. Client application directly accesses the server data. In a three tier architecture there is a data server, a client application and a server application. Client application calls the server application which in turn fetches data from the data server and returns back to client application.

c.) Alpha testing and Beta testing

Alpha testing is conducting acceptance testing in the environment where the application was developed. It is done by the customer. Beta testing is conducting acceptance testing is the customer environment. It is done by the group of customers or users who will actually be using it.

d.) Static testing and dynamic testing

Static testing is checking the application without actually running the application whereas dynamic testing checks the application by running it.
