Tomcat (Apache Tomcat)

Apache Tomcat is an open-source software that acts as a web server and servlet container for Java applications. It allows developers to run Java-based web applications and serves as the bridge between users' requests and the applications' responses. Essentially, when you visit a website built in Java, Tomcat processes the request, executes the necessary code, and delivers the resulting web page to your browser. It's widely used for its reliability, scalability, and ease of integration with various technologies, making it popular among developers for hosting Java web applications.
