32-bit is also a term given to a generation of microcomputers in which 32-bit microprocessors are the norm. A 32-bit register can store 2 different values. The signed range of integer values that can be stored in 32 bits is -2147483648 through 2147483647 . Hence, a processor with 32-bit memory addresses can directly access 4 GiB of byte-addressable memory.
