Breakdown of the Problem

The question asks about the use of servlets in a web application context. It's important to understand what a servlet is and its role compared to the provided options.

Relevant Concepts

1. Servlet: A servlet is a Java program that runs on a server, handling requests and responses in a web application.
2. Web Application Components:
   • Tomcat Server: This is a web server and servlet container used to execute Java servlets.
   • Client: The end-user's interface, typically a web browser that makes requests to the server.
   • Applet: A small application designed to run in a web browser but not directly related to how servlets function.

Analysis and Detail

1. Tomcat Server: Servlets are deployed on a server like Tomcat, which processes requests coming from clients, executing the servlet, and sending responses back.
2. Client: Clients don't directly use servlets; instead, they make requests that servlets process.
3. Applet: Applets are Java programs that run on the client-side and aren't directly related to servlet functionality.

Verify and Summarize

The servlet is primarily associated with the server-side processing of requests in a web application. The correct choice is the component that relates directly to where servlets are utilized.

Final Answer

Tomcat server is the correct answer, as servlets run on a server designed to handle Java applications, making it a vital component of web applications.
