Software bus
Software architecture model
A software bus is a software architecture model where a shared communication channel facilitates connections and communication between software modules. This makes software buses conceptually similar to the bus term used in computer hardware for interconnecting pathways.[1]
In the early microcomputer era of the 1970s, Digital Research's operating system CP/M was often described as a software bus.[2][3] Lifeboat Associates, an early distributor of CP/M and later of MS-DOS software, had a whole product line named Software Bus.[4] D-Bus is used in many modern desktop environments to allow multiple processes to communicate with one another.
