An address space is the total namespace available for identifying discrete objects in an information-processing system. (These names are usually termed 'addresses'.)
Most commonly, it refers to the maximum amount of main memory a given CPU architecture can handle, but it appears in other contexts as well; e.g. the Internet Protocol Version 4 has an address space of 2^32 names (from its 32-bit addresses).
