What is the main function South and North Bridge on the motherboard?
The northbridge links the CPU to very high-speed devices, especially RAM and graphics controllers, and the southbridge connects to lower-speed peripheral buses (such as PCIor ISA). In many modern chipsets, the southbridge contains some on-chip integrated peripherals, such as Ethernet, USB, and audio devices.
What is the role of North Bridge?
The Northbridge is the controller that interconnects the CPU to memory via the frontside bus (FSB). It also connects peripherals via high-speed channels such as PCI Express.
How does a North Bridge work?
The high-speed part of a common chipset architecture in a computer. The Northbridge is the controller that interconnects the CPU to memory via the frontside bus (FSB). It also connects peripherals via high-speed channels such as PCI Express.
What does Apple call a motherboard?
Apple started calling their ‘mainboards’ logic boards and it stuck. they started this in the 80s. A Mac is a PC, if you think about it, its a personal computer. but we call a PC, is a PC clone. that is, it is a clone of an IBM computer.
What does the south bridge control?
The southbridge is an IC on the motherboard responsible for the hard drive controller, I/O controller and integrated hardware. Integrated hardware can include the sound card and video card if on the motherboard, USB, PCI, ISA, IDE, BIOS, and Ethernet.
What is a South Bridge in a motherboard?
The motherboard has a logical chip set compromising of two chips namely North and South bridge. It is named South bridge as it sits in the South direction of Peripheral Component Interconnect or PCI bus of motherboard. Unlike North bridge, this chip is not directly connected to the CPU.
Where is the Northbridge on a motherboard?
Northbridge is located in the northern section of the motherboard. It is also known as the host bridge. It is directly connected to the CPU, RAM, AGP, and PCI Express slots.
What is the function of North Bridge in a CPU?
North bridge acts as a medium of communication between South bridge and Central Processing Unit. South bridge controls all the Input and Output activities via CPU. Thereby it is also named as I/O Controller Hub as it acts as a hub for all the I/O processing and functionalities.
What is the difference between a northbridge and a southbridge?
The main difference between northbridge and southbridge is in the connection to the CPU. While northbridge is directly connected to the CPU, southbridge connects to the CPU via the northbridge.
