Describe the chipset on the motherboard



The gateway between a processor and other components is a set of interface controllers generically called the chipset. Traditional chipsets include a Northbridge with memory controller and graphics card interface, and a Southbridge containing slower expansion card interfaces and various peripheral, storage, and communications controllers. The closest match to this traditional definition, AMD’s Socket AM3+ deviates mostly in that the memory controller is on the CPU.

We have all heard about the latest chipsets from Intel, VIA, Nvidia, SiS and more and how much better they are. But what does the chipset actually do on the motherboard? We know what the CPU does, we know what the graphics card is for and why we have a hard disk drive but not many people know too much about the chipset. Hopefully we can shed a little light on the working of the chipset and why they differ from one chipset to the next.

The chipset normally consists of two major microchips. A Northbridge with memory controller and graphics card interface, and a Southbridge containing slower expansion card interfaces and various peripheral, storage, and communications controllers. Developments in chip technologies have meant that chipset and CPU manufacturers are changing the way the chipset layout works, for example some CPU’s come with a built in memory controller taking that job from the North Bridge, some chipsets have incorporated the north and south bridge in the same chip, but for now we will look at the standard setup.

The North Bridge Handles data for the graphics port whether that be AGP or PCI express and the main memory which includes the FSB (Front side bus). Although both chips are required for the PC to work the North Bridge handles most of the very important tasks such as the connection between the CPU and main memory bank. The South Bridge handles data from the PCI x1 slots and can also have integrated components such as Audio and/or onboard graphics.

The North and South bridges will have different chip names even though they are very often paired with the same opposite bridge to come under the collective name of the chipset. Below is a diagram of the KT600 chipset from VIA technologies.

Since we now know that the chipset handles an incredible amount of data, its important to see which chipsets are performing the best. Firstly to choose a chipset that supports your CPU. You obviously cant have a chipset designed for an Intel CPU if your using a AMD based CPU of course the motherboard you buy will clearly display which model of CPU it is for. Then the best way to see which chipsets are performing the best is to look at benchmarks on various internet sites. A slow chipset can be as damaging to your systems overall speed as a slow CPU or slow memory. The slowest component always dictates the overall speed at any given time. If you have a poor performing chipset, then any time that your computer is sending and receiving data from the graphics card or main memory, then the system is struggling.



12,Describe the Booting: When we start our Computer then there is an operation which is performed automatically by the Computer which is also called as Booting. In the Booting, System will check all the hardware’s and Software’s those are installed or Attached with the System and this will also load all the Files those are needed for running a system.

In the Booting Process all the Files those are Stored into the ROM Chip will also be Loaded for Running the System. In the Booting Process the System will read all the information from the Files those are Stored into the ROM Chip and the ROM chip will read all the instructions those are Stored into these Files. After the Booting of the System this will automatically display all the information on the System. The Instructions those are necessary to Start the System will be read at the Time of Booting.
