Mapping is either a translation database from the names in one namespace to those of another, or the process of doing that translation.
For instance, memory management generally involves mapping from the address space of a process to addresses in physical main memory. This may be done in a simple way, with base and bounds registers, or the use of page tables when virtual memory is being used.
Similarly, the Domain Name System maps from human-readable names (organized in a hierarchical system), to Internet Protocol addresses.
