Address bus

An address bus is a computer bus (a series of lines connecting two or more devices) that is used to specify a physical address.

Address space

In computing, an address space defines a range of discrete addresses, each of which may correspond to a network host, peripheral device, disk sector, a memory cell or other logical or physical entity.

Addressing mode

Addressing modes are an aspect of the instruction set architecture in most central processing unit (CPU) designs.

Bus (computing)

In computer architecture, a bus (a contraction of the Latin omnibus) is a communication system that transfers data between components inside a computer, or between computers.
