In this tutorial, we will be covering the concept of Paging in the Operating System.Paging permits the physical address space of a process to be non-contiguous. It is a fixed-size partitioning scheme. In the Paging technique, the secondary memory and main memory are divided into equal fixed...
In the case of pure demand paging, there is not even a single page that is loaded into the memory initially. Thus pure demand paging causes the page fault. When the execution of the process starts with no pages in the memory, then the operating system sets the instruction pointer to the...
PURPOSE:Toattain an on-demand paging ODP system in an operating system that can reduce the overhead of a task of higher priority caused by the push-pull operations and can run the task with priority. CONSTITUTION:An ODP mechanism 2 selects a proper page to be pushed with the LRU control...
In order to record where each virtual page of the address space is placed in physical memory, the OS keeps aper-processdata structure known as apage table. The major role of a page table is to storeaddress translationsfor each of the virtual pages of the address space, thus letting us kno...

system. With one hundred active process (not uncommon on a modern system), we will be allocating hundreds of megabytes of memory just for page tables. As a result, we are insearch of some techniques to reduce this heavy burden. There are a lot of them, so let us get going. But not...
