Paging is a memory management scheme that eliminates the need for contiguous allocation of physical memory, thereby avoiding issues like fragmentation. In this process, the virtual memory is divided into fixed-size blocks called pages, while the physical memory is divided into page frames. When a program is executed, its pages are loaded into available page frames, allowing the system to access them as needed. This method allows for efficient use of memory and enables processes to use more memory than what is physically available through techniques like swapping pages in and out of disk storage.
Paging generally produces better solutions for fragmentation compared to segmentation. This is because paging eliminates external fragmentation by dividing memory into fixed-size pages, allowing processes to be loaded into any available memory frame. In contrast, segmentation can lead to external fragmentation as segments can vary in size, potentially leaving unusable gaps in memory. Therefore, while both methods manage memory allocation, paging is often more efficient in handling fragmentation issues.
Paging together with segmentation offers the advantages of both memory management techniques, enhancing efficiency and flexibility. Paging allows for non-contiguous memory allocation, which reduces fragmentation and optimizes memory usage. Meanwhile, segmentation provides a logical division of memory, enabling programs to be organized into meaningful units, such as functions or data structures. This combination allows for better access control, easier sharing of code, and improved overall system performance.

Paging You ended in 1946.
Difference between paging and what?
Default paging is what it already comes with. It is a pre-made template, while custom paging would be ones on ideas and creativity.
