Which of the following is a bus mastering method? (Select TWO).

Bus mastering allows a peripheral device, such as a network interface card or storage controller, to initiate and control data transfers directly to system memory without involving the central processing unit as an intermediary.

Mediation between the northbridge and the processor is a function typically handled by the chipset's northbridge or integrated memory controller, not a general bus mastering method for data transfer.

In bus mastering, a peripheral device can communicate and exchange data with another peripheral device or memory directly over the system bus, effectively offloading this data transfer task from the main processor.

Transferring data to the processor and then on to memory describes a CPU-centric data transfer model, which bus mastering aims to circumvent by enabling direct device-to-memory transfers.

Mediation between the southbridge and the processor is a function typically handled by the chipset's southbridge (or I/O controller hub) and the processor's bus interface, not a bus mastering method.
