Computer Hardware Terms, Glossary and Dictionary

64-bit

In computer architecture, 64-bit describes integers, memory addresses or other data units that are, at most, 64 bits (8 octets or 8 bytes) wide, or describes CPU and ALU architectures based on registers, address buses, or data buses of that size. As of 2004, 64-bit CPUs are common in servers, and have recently been introduced to the (previously 32-bit) mainstream personal computer arena in the form of the AMD64, EM64T, and PowerPC 970 (or "G5") processor architectures
