What is paging? Name the different paging techniques.
Paging is a memory management method that permits the physical-address space of a process to be noncontiguous. Paging evades the considerable problem of fitting the varying-sized memory chunks onto the backing store, from which the majority of the previous memory-management schemes suffered. The fragmentation problem undergo in the backing store is as well avoided. For the reason benefit over the previous methods, paging in its different forms is commonly used in most operating systems.
The various paging techniques are.
1. Multilevel paging or hierarchical paging method.
2. Hashed page table method.
3. inverted page table method
4. shared pages method
