Imagine you have a book that is very big and has a lot of pages. It's hard to read the whole book at once, so you just read a few pages at a time.
Now, imagine your computer has a lot of programs and information that it needs to access. This is like the big book. But just like it's hard to read the whole book at once, it's hard for the computer to access all the information at once.
That's where paging comes in. Paging is like dividing the book into smaller sections, called pages. When the computer needs to access information, it takes out just one page at a time, instead of the whole book.
This makes it easier for the computer to find the information it needs quickly, and also saves space in the computer's memory.
So, paging is like dividing a big book into smaller pages, and helps the computer access information more efficiently.
