What is independent process? A process is independent it cannot influence or be affected by the other processes implementing in the system. Any process does not share data with
Hashed page tables A common approach for handling address spaces larger than 32 bits is to use a hashed page table. Every entry in the hash table having a linked list of elemen
Enhanced second-chance algorithm. When we increase the second-chance algorithm by considering both the reference bit and the modify bit as an order pair. We have the following
