E Correct answer
Explanation

Extreme Prototyping as a development process is used especially for developing web applications. Basically, it breaks down web development into three phases, each one based on the preceding one. The first phase is a static prototype that consists mainly of HTML pages. In the second phase, the screens are programmed and fully functional using a simulated services layer. In the third phase, the services are implemented. The process is called Extreme Prototyping to draw attention to the second phase of the process, where a fully functional UI is developed with very little regard to the services other than their contract.

Multiple choice

An applet

  1. is an interpreted program that runs on the client

  2. tracks the number of visitors to a website

  3. is a compiled program that usually runs on the client

  4. collects data from visitors to a website

  5. none of these

C Correct answer
Explanation

An applet is a small application compiled to bytecode that runs on the client side, typically within a browser or JVM. While applets are interpreted at runtime, they are first compiled to bytecode before distribution. Visitor tracking and data collection are web server functions, not applet characteristics. The key distinction is that applets are pre-compiled programs delivered to clients.
