G As implicitly assumed earlier, the first physical frame is reserved for the OS; the other frames are initially free. You will initially use the following frame allocation scheme: (1) allocate the physical page in order of frame number, starting from 1, 2, 3, (2) when there are no free physical frames, you will need to use the LRU policy for page replacement. That means, the page that is least recently used (accessed) will be allocated to the new request.
