Servlets are an integral part of any J2EE Web application. The key benefits of using Servlets in our web applications are:

b. Servlet API is standard and available easily on the internet (like JSPs)

How do servlet handle multiple simultaneous requests?
Servlets handle multiple simultaneous requests through a multi-threaded model provided by the Java Servlet API. When a servlet is deployed, the servlet container creates a separate thread for each incoming request, allowing multiple requests to be processed concurrently. This means that each request can be handled independently, with the servlet's service method being invoked in a separate thread for each request. However, developers must ensure thread safety when accessing shared resources to prevent data inconsistencies or conflicts.

A loosely coupled system offers advantages such as increased flexibility and scalability, allowing components to be modified or replaced independently without affecting the entire system. This modularity can enhance resilience, as the failure of one component is less likely to disrupt others. However, disadvantages include potential performance overhead due to the need for communication between loosely connected components, and the complexity of managing interactions and dependencies, which can lead to challenges in system integration and consistency.
