2. [10 Points] Consider a system with paging-based memorymanagement, whose architecture allows for a 4GB virtual addressspace for processes. The size of logical pages and physical framesis 4KB. The system has 8GB of physical RAM. The system allows amaximum of 1K processes to run concurrently and uses a 10-bitnumber to represent the PID. (Assume 1K = 1024.) A) [5 Points]Assuming the OS uses hierarchical paging; calculate the maximummemory space required to store the page tables of all processes inthe system. Assume that each page table entry requires anadditional 10 bits (beyond the frame number) to store variousflags. Assume page table
