Southbridge (computing)

In computing, a southbridge is a component of a traditional two-part chipset architecture on motherboards, historically used in personal computers. It works alongside the northbridge to manage communications between the central processing unit (CPU) and lower-speed peripheral interfaces. The northbridge typically handled high-speed connections such as…
