Paging

Let’s say you have a computer program that contains hundreds of thousands of instructions. More often than not, these instructions occupy a much larger size than what the computer’s memory can handle. Paging is an essential memory management technique that breaks that large program into smaller more manageable pieces. This allows the computer to only load the pieces that are in use into memory.

What is Paging in a Nutshell

Think of paging as a way to organize information on a computer's memory. To make it easier to keep track of, the computer divides memory into equal sections called pages. Each of these pages is kept on a disk, and they're only loaded into memory when they're needed. Paging is an essential memory management technique that allows computers to handle large programs and files. Without paging, you would have to reload the entire program into memory every time a new section was needed. With paging, only the specific pages needed are accessed.

It's important to note that paging is invisible to users as it happens automatically. You don’t need to worry about how your computer is managing memory, and it will continue to work efficiently.
