Definitions for "Address bus"
A set of wires running from the central processing unit (CPU) to random-access memory (RAM).
The electronic channel, usually from 20 to 32 separate lines wide, used to transmit the signals that specify locations in memory. The number of lines in the address bus determines the number of memory locations that the processor can access, as each line carries one bit of the address. An address bus of 20 lines ( used in early Intel 8086/8088 processors) can access 1MB of memory, one of 24 lines ( as int he Intel 80286) can access 16MB, and an address bus of 32 lines (as used by Intel 80386,80486, and later processors, or the Motorola 68020) can access over 4 GB.
A unidirectional set of signals used by a computer to point to memory locations in which it is interested.
A type of communication of the microprocessor which involves sending and receiving of data or instructions.
