Meaning – The term page, refers to a fixed-length block that has a virtual address and is transferred as a unit between real storage and auxiliary storage.

It also refers to a fixed-length block of instructions, data, or both that can be located in processor storage or in the page data set on disk.

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. Similarly, a page frame is the smallest fixed-length contiguous block of physical memory into which memory pages are mapped by the operating system.

Example of usage“Page size is usually determined by the processor architecture. Traditionally, pages in a system had uniform size, such as 4,096 bytes. However, processor designs often allow two or more, sometimes simultaneous, page sizes due to its benefits. There are several points that can factor into choosing the best page size.”
