Data Flow diagramsCole and James

Control Bus This is where we control how we save

and how we open our documents up. This controls how, where and why we install our documents and our apps. This tells the other busses what to do.

Data Bus The data bus lets us transfer our work to

different places.

Address Bus The address bus lets you locate the

work where you have recently saved it. It’s like a post code, you put it into your

satnav and it will take you there.
