But first, let me explain to you what's memory page and how we'll program access memory.

00:25

When your app reads or writes variables, it stores them in a volatile memory, known commonly as physical memory or RAM.

00:34

To simplify its organization and reduce waste space, data is stored in a fixed size block, and we call this block a memory page.

00:45

And on Android, historically, there are 4 KB each.

00:49

And when an app needs more memory, more memory pages will be allocated.

00:55

Each memory will have its own physical address to locate it inside the physical memory.
