Which statement is NOT true regarding web applications?

The statement regarding the need for virtualization of the client's machine is not true for web applications. Web applications are designed to run within a web browser, allowing users to access them directly without the need for additional software installations or virtualization efforts on the client side.

Web applications primarily rely on the server to host the application and its logic, while clients interact with it through their web browsers, making them accessible from various devices as long as they have internet connectivity. This model leverages the server's resources to deliver content and functionality, freeing the client device from the burden of running heavy processing tasks or needing a specific operating environment.

Since virtualization typically involves creating virtual devices that emulate hardware or software systems to run applications, it is not a requirement for web applications, which operate in a more lightweight and flexible manner by simply utilizing existing browser capabilities. The other statements accurately describe fundamental aspects of web applications, reinforcing that virtualization is not necessary for their functioning.
