Processor and System BUS

The controller is a device that manages the operation of a system or subsystem. In computer engineering, a controller is often used as an interface between the processor and other devices or systems. The controller is responsible for controlling the flow of data and commands between the different components of a system.

The processor bus is a communication pathway that connects the processor to the memory and other components of the computer system. The system bus is a communication pathway that connects all the devices and subsystems of the computer system.

Answer Explanation

The controller is connected to the system bus. This is because the system bus is responsible for connecting all the devices and subsystems of the computer system. The controller acts as an interface between the processor and other devices or systems, and therefore it needs to be connected to the system bus to communicate with other components of the computer system.

The processor bus is responsible for connecting the processor to the memory and other components of the computer system. While the controller may interact with the processor, it is not directly connected to the processor bus.

Conclusion

In conclusion, the controller is connected to the system bus. This is because the system bus is responsible for connecting all the devices and subsystems of the computer system. The processor bus is responsible for connecting the processor to the memory and other components of the computer system.
