What is the principle of browser tabs on PC and tablet?

Question

Browsers

Here I open a lot of new tabs in the browser on the computer and the computer is loaded harder and slows down, it also reboots when it is reopened. However, on a tablet, I open at least ten, at least a hundred tabs, this has almost no effect on performance, even if I accidentally turn it off and on by logging into the browser (with those very 10-100 tabs), the tablet does not hang.
The question is, how are open tabs on a PC and a tablet loaded in such a different way that the first one completely freezes tightly, and the second at least something (even with 100 tabs, checked)?

Answer 1

On a PC, each tab creates a new process that consumes RAM. Over time, the memory starts to run out and the PC uses a slow paging file on the disk, everything slows down.
On android it's about the same, but as soon as the memory gets low, the tabs in the background are "freed" - usually a small piece of information will remain, like a preview and a link to the site.
When you switch to any tab on a PC, everything on it will remain as it was.
When switching to the old background tab on the tablet, the page will reload

Answer 2

I use The Great Suspender for chrome . You can configure which tabs to load and which not.
