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.
what a wicked page, really helpfull Difference between pre-tensioned and post-tensioned?
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
Right in this moment you are reading a web-page.
The space between a page's content and the edge of the page is called "margin" in printing, as well as web design.
the print command gives an order to the computer to print a page but the print preview gives us a preview of the way in which it has to be printed
difference between home page and effective home page
A person in need and a ............................ Why are you readig tis? =)
A web page is just one page, a web site is a collection of pages. Much like the difference between a page and a book.

DHTML combines HTML, JavaScript, the HTML DOM, and CSS.
an automatic page break is a generated page break that automatically puts a new page onto the document.
There is one basic difference between a footnote and an endnote: where it is placed. A footnote is at the bottom of a page and an endnote is at the end of a document.
the difference between a iphone 4 and iphone 5 is that the back is made out of aluminium and it has 5 row of apps on a page

The page header repeats on every page. The report header is just on the first page.
briefly explain the home page
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
