In Paging, a process address space is broken into fixed sized blocks called pages. In Segmentation, a process address space is broken in varying sized blocks called sections. Operating System divides the memory into pages. ... During segmentation, a logical address is divided into section number and section offset.

Paging is a method or techniques which is used for non-contiguous memory allocation. It is a fixed size partitioning theme (scheme). Segmentation is another non-contiguous memory allocation scheme like paging. like paging, in segmentation, process isn’t divided indiscriminately into mounted(fixed) size pages. It is variable size partitioning theme.

Paging is a storage mechanism that allows OS to retrieve processes from the secondary storage into the main memory in the form of pages. In the Paging method, the main memory is divided into small fixed-size blocks of physical address, which is called frames.

Segmentation method works almost similarly to paging, only difference between the two is that segments are of variable-length whereas, in the paging method, pages are always of fixed size.

Segmentation is a method of memory management. Memory is managed in segments that are of variable or fixed length, depending upon the processor. Segments originated on 16-bit processors as a means to access more than 64K of memory.

Paging allows a process to have a larger address space than there is physical memory available.
