A page table is the data structure used to store the mapping between virtual addresses and physical addresses in memory. The RAM is divided into fixed-size page frames, creating system Page Table Entries to store information about these page frames, and mapping them. System Page Table Entries are small kernel-mode buffers of memory that are used to communicate with the disk I/O subsystem and the network.
