Is this information accurate?
I apologize in advance if this kind of post is not allowed here, and, if its not, if anyone knows of a better place to ask instead that would be rad
I am studying and this excerpt from the study guide I was given isn't matching up with some of my other sources. Could someone please verify if any of this is correct/misleading? For instance, it says paging divides virtual memory and physical memory into pages, but isnt physical memory divided into frames?
Excerpt:
"Virtual RAM: also known as virtual memory, is a memory management technique used by operating systems to extend the apparent amount of RAM available to applications. This is done by using a portion of a computer's storage (such as an SSD or HDD) to simulate additional RAM.
Paging: The operating system divides physical memory and virtual memory into small fixed-sized blocks called pages. When the system runs out of physical RAM, it can swap inactive pages to the storage device, freeing up RAM for active processes.
Pagefile/Swap Space: On Windows systems, this is often referred to as a pagefile, while on Unix-like systems, it is called swap space. This file or partition on the storage device is used to store pages that are moved out of physical RAM.
Address Translation: The CPU uses a memory management unit (MMU) to translate virtual addresses (used by programs) into physical addresses (used by the hardware). This allows applications to use more memory than is physically available."
