What Is Motherboard

What Is Mother Board 

A motherboard is the main printed circuit board  (PCB)  in a computer , the motherboard is a computer,s central communications backbone
connectivity point, through which all components and external peripherals connect.

The large PCB of a motherboard may include 6-14 Layers of fiberglass , copper connecting traces and copper planes for power and signal isolation
additional components can be added to a motherboard through its expansion solts. these may include processor sockets , DIMM . HTX , PCI , PCIe
and M.2 solts as well as power supply connections. typically motherboard  offer additional connectivity through a southbridge chip such as PCI , SATA,
thunderbolt ,USB , and more CPU , to RAM , and PCIe are generally connected through point-to-point interconnects such as hypertransport (HT) , quick
path interconnect (QPI) or ultrapath interconnect (UPI) . often choosing a motherboard determines many of the features a desktop will have..

Motherboard Part

(1) A CPU socket - the actual CPU is directly soldered onto the socket since high speed CPUs                 generate a lot of heat, sinks and mounting points for fans right next to the CPU sockt..
   

(2) A power connector to distribute power to the CPU and other components.


(3) Slots for the system,s main memory typically in the form of DRAM chips.


(4) A chips forms an interface between the CPU , the main memory and other components . on may          types of motherboard this is referred to as the northbridge . this chip also contains a large heat              sink.
   

(5) A second chip controls the input and output (I/O) function. It is not connected directly to the               CPU but to the northbridge. this I/O controller is referred and southbridge combined are referred         to as the chipset.

   
(6) Serveral connectors which provide the physical interface between input and output devices and         the motherboard the southbridge  handles these connections
