    - Minimum number of pages based on instruction set architecture are required by every process.

    - An example of IBM 370: 6 pages are required to handle MVC (storage to storage move) instruction

    - This instruction is of 6 bytes, which might span across 2 pages.

    - 2 pages are required to handle from.

    - 2 pages are required to handle to.
