A barbershop comprises of a waiting room with ‘n’ chairs and a barber room with one barber chair. If there are no customers to be served, then the barber goes to sleep.
Assume a logical address space is 1KB, and the page-size is 16 bytes. Suppose no page is in the main memory for this process initially and the pure demand paging is used. Current free frame list is
