'How much memory is used for page tables, when there are 100 processes running in the system?
Consider a virtual memory system that has a 4 GB (32 bits) virtual address space. The system uses a single-level page table and the page size is 1KB. Each entry of the page table contains two parts: a valid bit and the corresponding physical page frame number (PFN). The system has a maximum of 32MB physical memory. How much memory is used for page tables, when there are 100 processes running in the system?
