Detailed explanation-1: -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.

Detailed explanation-2: -Paging is a function of memory management where a computer will store and retrieve data from a device’s secondary storage to the primary storage. Memory management is a crucial aspect of any computing device, and paging specifically is important to the implementation of virtual memory.

Detailed explanation-3: -Paging technique is the mapping done from virtual address to physical address by the MMU (a hardware device). The Physical Address Space is divided into multiple fixed-size blocks. These blocks are called frames. Whereas, Logical address Space is divided into fixed-size pages.

Detailed explanation-4: -In Operating Systems, Paging is a storage mechanism used to retrieve processes from the secondary storage into the main memory in the form of pages. The main idea behind the paging is to divide each process in the form of pages. The main memory will also be divided in the form of frames.

Detailed explanation-5: -Demand paging is a technique used in virtual memory systems where the pages are brought in the main memory only when required or demanded by the CPU. Hence, it is also named as lazy swapper because the swapping of pages is done only when required by the CPU.

Detailed explanation-6: -When a computer runs out of RAM, the operating system (OS) moves pages of memory over to the computer’s hard disk to free up RAM for other processes. This process is designed to ensure that the OS will not run out of memory and crash. However, overreliance on memory paging can impair performance.
