Very Easy bchooo ... Linux also near to popular Windows .. in All Aspects

In certain categories, one family of operating systems dominates, for example, most desktop and laptop computers use Microsoft Windows, while most supercomputers use Linux.

Solution For GDB of CS604- Operation System.
Remember me in your prayers.

Linux is the kernel nothing more. The software built on top of the kernel is GNU software meant to finish out the OS. Take Linux Mint, for example, which is a good "beginners distort"(which is exactly what I like about it, is very easy and simple to use. People who know Windows are easily able to find their way around it. In a lot of ways, Windows is the opposite of user friendly, and Linux Mint shows how not user friendly Windows is, when compared to each other. It's more about showing the software alternatives that Linux bistros use. Not that the system is hard to use or anything on its own.

Page tables are used to translate the virtual addresses seen by the application into physical addresses used by the hardware to process instructions; such hardware that handles this specific translation is often known as the memory management unit. A page, memory page, or virtual page is a fixed-length contiguous block of virtual memory, described by a single entry in the page table. It is the smallest unit of data for memory management in a virtual memory operating system. Each entry in the page table holds a flag indicating whether the corresponding page is in real memory or not. If it is in real memory, the page table entry will contain the real memory address at which the page is stored. When a reference is made to a page by the hardware, if the page table entry for the page indicates that it is not currently in real memory, the hardware raises a page fault exception, invoking the paging supervisor component of the operating system. Systems can have one page table for the whole system, separate page tables for each application and segment, a tree of page tables for large segments or some combination of these. If there is only one page table, different applications running at the same time use different parts of a single range of virtual addresses. If there are multiple page or segment tables, there are multiple virtual address spaces and concurrent applications with separate page tables redirect to different real addresses. Sosupport them to used Larger Page Tables can be implemented on Secondary storage devices they can’t slow down the systems.
