Question

a) In order to communicate between devices inside a computer. A wire routing scheme is needed such that all the devices remains connected without wasting much wires and the scheme must be scalable to add new devices with ease. Connect the devices mentioned in the diagram, using a single bus controller.

Answer 1

This is how we can connect the given device using a single bus controller:

Explanation:

• Buses: Input Output will be connected to the Processor and Memory using a Bus.  

• A bus is a mutual communication link. It utilises one set of wires to link multiple subsystems.

• In this situation a bus can be used in the following way, as given in the attached image.

• Advantages of this connection are:

• Versatility: New devices can be added without any hassle.

• Transport: Peripherals can be shifted between computer systems that employ the same bus standard.

• Low Cost: A single set of wires can be pooled in multiple ways.
