Understanding the main difference between websites and web applications

Which statement best describes the primary difference between a website and a web application?

A A website uses only images and text, whereas a web application uses only videos and animations.

B A website always requires user login, but a web application never does.

C A website is installed on your computer, but a web application runs only on mobile devices.

D A website mainly provides static information, while a web application allows user interaction and dynamic content.

💡 Hint

Think about whether the user can interact or just read content.

Websites usually show information that doesn’t change much and users mainly read it. Web applications let users interact, like filling forms or using tools online.

Trace user interaction in a web application

Imagine a user logs into a web application and submits a form. What is the correct sequence of events?

A 3,1,2,4

B 1,2,3,4

C 1,3,2,4

D 2,1,3,4

💡 Hint
