Final answer:
The Southbridge chipset traditionally communicates with peripheral devices such as Ethernet adapter cards and I/O controllers, rather than RAM, which uses the Northbridge or direct CPU integration in modern PCs.
Step-by-step explanation:
The question pertains to the communication pathways between PC components and the CPU within a computer system. Specifically, the components that communicate through the Southbridge chipset are usually peripheral devices and I/O ports. Historically, the Southbridge has managed a variety of services including the PCI bus, USB, audio, SATA, and sometimes Ethernet controllers. However, with advances in chipset design, the distinction between Northbridge and Southbridge has become less clear in modern systems.
From the options provided, the two components that would traditionally communicate through the Southbridge are:
- 64-bit gigabit Ethernet adapter card
- Internal components such as audio or USB controllers. RAM typically communicates with the CPU via the Northbridge or memory controller hub in older PC architectures, or directly if integrated into the CPU itself in more recent designs.
Therefore, the components likely to use the Southbridge for communication with the CPU are interface cards like Ethernet adapters and internal I/O services rather than RAM.
