Its main functions are as follows: To serve as a central backbone to which all other modular parts such as CPU, RAM, and hard drives can be attached as required to create a computer; To be interchangeable (in most cases) with different components (in particular CPU and expansion cards) for the purposes of customization and upgrading
Motherboard diagram, created in 2007, which supports many on-board peripheral functions as well as several expansion slots. The functionality found in a contemporary southbridge includes: [8] [2] PCI bus. A south bridge may also include support for PCI-X. Low speed PCI Express (PCIe) interfaces usually for Ethernet and NVMe. ISA bus or LPC ...
A CPU socket is made of plastic, and often comes with a lever or latch, and with metal contacts for each of the pins or lands on the CPU. Many packages are keyed to ensure the proper insertion of the CPU. CPUs with a PGA (pin grid array) package are inserted into the socket and, if included, the latch is closed.
A typical motherboard will have a different number of connections depending on its standard and form factor. A standard, modern ATX motherboard will typically have two or three PCI-Express x16 connection for a graphics card, one or two legacy PCI slots for various expansion cards, and one or two PCI-E x1 (which has superseded PCI).
Because computer parts contain hazardous materials, there is a growing movement to recycle old and outdated parts. [66] Computer hardware contain dangerous chemicals such as lead, mercury, nickel, and cadmium. According to the EPA these e-wastes have a harmful effect on the environment unless they are disposed of properly.
If MB has Integrated Graphics it must be connected somewhere to north bridge to get access to RAM. But it's not on south br definetely. Intel GMA is connected to Noth br. Modern Intel HD are located on CPU and use memory from L4 cache and RAM. 17:31, 16 April 2009: 370 × 570 (54 KB) Moxfyre: latest version from en:File:Motherboard diagram.svg
Comparison of some common motherboard form factors (pen for scale). Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics.
Intel 5 Series is a computing architecture introduced in 2008 that improves the efficiency and balances the use of communication channels in the motherboard.The architecture consists primarily of a central processing unit (CPU) (connected to the graphics card and memory) and a single chipset (connected to motherboard components).
