In segmentation, the address space is typically divided into a preset number of segments like data segment (read/write), code segment(read-only), stack(read/write) etc. And the programs are divided into these segments accordingly. Logical addresses are represented as tuple <segment, offset>.
While with paging, the address space is divided into a sequence of fixed size units called "pages". And logical addresses take the form of a tuple <page, offset>.
Each of these techniques offer several benefits e.g., segmentation offers better security since the segments are pre-defined and we can avoid spurious reads/writes at the time of address translations etc.
On the other hand, paging helps reduce fragmentation and ensures better memory management.
So, most modern operating systems employ a combination of both these techniques for their memory management.

How do you get segmented base and offset when you have logical address?
You cannot. The conversion goes this way: segment+offset -> [segment-table] -> linear_address -> [page-table] -> physical_address PS: In most cases there is only one (4GB long) segment (or one code-segment and one data-segment), so offset is quite the same as linear address

Difference between a page and a segment?
Paging is a virtual memory scheme which is transparent to the program at the application level and which divides memory into fixed-size blocks, such as 4 KBytes. The segmentation memory management scheme imposes a greater book-keeping burden on the application, and refers to memory using segments of variable size. segmentation is a logical unit visible to the user's program and id of arbitary size whereas paging is a physical unit invisible to the user's view and is of fixed size
