address space

A computer's address space is the total amount of memory that can be addressed by the computer. The term may refer to the physical memory (RAM chips) or virtual memory (disk/SSD). For example, a 32-bit computer can address 4GB of physical memory and as much as 64TB of virtual memory. See address register and flat address space.
