Address bus


Address bus: An address bus is a computer bus that is used to specify a physical address. When a processor or DMA-enabled device needs to read or write to a memory location, it specifies that memory location on the address bus. The width of the address bus determines the amount of memory a system can address. For example, a system with a 32-bit address bus can address 2³² memory locations. If each memory address holds one byte, the addressable memory space is 4 GB.
