All codes written in ZUML or Java file are executed in server side ?
A
Correct answer
Explanation
ZK is a server-side framework where ZUML markup and Java code are executed on the server. The framework generates HTML and JavaScript that is sent to the client browser. All business logic, event handling, and component creation happens server-side, with ZK's AJAX engine handling client-server communication seamlessly. This is a fundamental architectural characteristic of ZK.
