Description: The Inverted Page Table is a fundamental data structure in virtual memory systems, designed to manage the mapping between physical and virtual addresses. Unlike conventional page tables, which associate each virtual page with its corresponding physical page, the inverted page table maintains a single entry for each physical page frame. This means that instead of having an entry for every virtual page, the inverted page table has an entry for each physical memory frame, reducing memory usage and improving efficiency in systems with a large number of processes or a high degree of address space usage. Each entry in the inverted page table contains information about the virtual page residing in that physical frame, as well as additional data such as the identifier of the owning process. This structure is particularly useful in operating systems that handle multiple processes simultaneously, as it allows for faster and more efficient access to memory. The implementation of inverted page tables is common in modern operating systems, where efficient memory management is crucial for overall system performance. In summary, the Inverted Page Table is a key tool in virtual memory management, optimizing resource usage and facilitating the effective execution of multiple processes.
