Final answer:
The mapping of files is managed by the file system, which utilizes file metadata to organize and locate files on a storage device. The page table, associated with virtual memory, does not manage file mapping.
Step-by-step explanation:
The mapping of files on a computer system is managed by the file system. When a file is created, the file system establishes a structure to organize data and manage the file's location on the storage device. This involves file metadata, which includes information like file size, creation date, permissions, and the address of the file on the disk.
The mentioned page table is associated with the virtual memory management in an operating system. It helps the system keep track of all virtual pages and their corresponding physical memory locations. However, it does not manage file mapping.
