| 1. | In paging, program is divided into fixed or mounted-size pages. | In segmentation, the program is divided into variable-size sections. |
| 2. | For the paging operating system is accountable. | For segmentation compiler is accountable. |
| 3. | Page size is determined by hardware. | Here, the section size is given by the user. |
| 4. | It is faster in comparison of segmentation. | Segmentation is slow. |
| 5. | Paging could result in internal fragmentation. | Segmentation could result in external fragmentation. |
| 6. | In paging, logical address is split into that page number and page offset. | Here, logical address is split into section number and section offset. |
| 7. | Paging comprises a page table which encloses the base address of every page. | While segmentation also comprises the segment table which encloses the segment number and segment offset. |
| 8. | A page table is employed to keep up the page data. | Section Table maintains the section data. |
| 9. | In paging, operating system must maintain a free frame list. | In segmentation, the operating system maintains a list of holes in the main memory. |
| 10. | Paging is invisible to the user. | Segmentation is visible to the user. |
| 11. | In paging, processor needs page number, offset to calculate the absolute address. | In segmentation, the processor uses segment number, and offset to calculate the full address. |
