IHA

Short for Intel Hub Architecture, IHA replaces the Northbridge and Southbridge found on computer motherboards. The IHA is found on all Intel 800 series chipsets, and like its predecessor, it has two parts: the GMCH and the ICH.

The GMCH (Graphics and AGP Memory Control Hub) is similar to the Northbridge and helps control the AGP (Accelerated Graphics Port) and memory.

The ICH (I/O Controller Hub), is similar to the Southbridge and is responsible for the I/O ports and PCI (Peripheral Component Interconnect) controller.
