An '''address space''' is the total [[namespace]] available for identifying discrete objects in an information-processing system.

Most commonly, it refers to the maximum amount of [[main memory]] a given [[central processing unit|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).
