In other words, page segmentation is a study technique devised by search engines to calculate the importance or relevance of a page to the web. Noise levels are calculated based on the amount of information contained in a website

Page segmentation is the process by which a scanned page is divided into columns and blocks which are then classified as halftones, graphics, or text.

In paged segmentation technique, the paging of memory happens under the control of segmentation. Typically program in memory is loaded into memory regions called segments. The segmentation of memory allows for separate and multiple memory regions for code, data and stack. This allows of simpler design of program address space. Each segment is further divided into fixed or variable sized pages and a page table data structure is constructed that maps virtual/linear address to physical address.

To decide scanned pages into block, columns - known as page segmentation.

Page segmentation is the process by which a scanned page is divided into columns and blocks which are then classified as halftones, graphics, or text. Past techniques have used the fact that such parts form right rectangles for most printed material.

I assume the question is about “paged segmentation”.

In paged segmentation technique, the paging of memory happens under the control of segmentation. Typically program in memory is loaded into memory regions called segments. The segmentation of memory allows for separate and multiple memory regions for code, data and stack. This allows of simpler design of program address space. Each segment is further divided into fixed or variable sized pages and a page table data structure is constructed that maps virtual/linear address to physical address.

The most famous example of the is type of paged segmentation is Intel i386 architecture (aka 80386). The 80386 processor allows software based enabling and disabling of paging. The default operating mode is pure segmentation but if the paging is enabled, the operating mode becomes “paged segmentation”.

As far as modern operating system design is concerned, Segmentation is not a popular concept. Most operating systems use linearity of addressing as a central tenet to program the address spaces even on CPUs like 80386 that support segmentation such that all code, data, stack and other segments are mapped to the same linear address range starting from 0 to MAX.

The operating systems like Windows NT and Linux which were designed for i386 use the technique described above to achieve linearly mapped segments.
