I was reading about the difference between a "view" and an "activity" and there, I discovered that the "Back button" is used to switch to the previous ACTIVITY.
Applying this concept to the Google Chrome browser app on Android: I somehow know that each tab in Chrome is a separate activity (right?). But what now confuses me is that when I am on a particular chrome tab, and I press the back button on my smartphone, it takes me to the previous page on the same tab. Does that mean that each "page" on every tab is a separate activity, and that whenever I open a website page on an existing tab, the webpage gets pushed into the stack as a running activity?
* the aim of this question is to help me better understand the concept of activity and activity-stack on android *
