Name came from Multics.
Basically, they had the whole address space consisting of mmaped files. address was (segment << 18) + offset (both up to 18 bits) and primitive was "attach segment (== file) to address space". Each segment had its own page table, BTW. Directories were special segments and contained references to other segments (both files and directories). Root had fixed ID. You could lookup segment by name.
