what is the function of a motherboard? - what is a smart board

The word "Motherboard" comes along with the appearance of printed circuit boards and microprocessor.
The motherboard allows additional devices and additional features to be added to the computer via a plug
In modules, the term extension is usually used when referring to the capability of the motherboard.
Before the invention of the microprocessor, most computers were large computers with powerful central processing units, usually stored in mainframe cabinets.
A back panel consisting of multiple interconnected slots is used to easily connect additional peripherals and features.
Modern PCs also use the word back panel.
The motherboard adds different functions by allowing additional components to be added throughout the computer system, just like the back panel.
As we all know, the dual inline memory module or dimm provides the main computer memory in the form of DRAM (
Dynamic random access memory).
Dynamic memory needs to be charged frequently, so that information is lost quickly when power is off.
These dimm are connected to the motherboard through a dedicated slot of the motherboard itself.
The chipset contained in the motherboard provides communication between the main processor and other external devices such as memory and graphics controllers, as well as some slower devices such as Ethernet, wireless controllers and USB devices.
A computer system must include
In order to store key information such as BIOS or firmware, unstable memory.
This type of memory is usually in the form of a flash ROM, which is not really suitable as a primary storage system for technical reasons.
Another variant of this type of memory is NVRAM (Non-
Random access memory Volatile)
Used with computer network devices such as routers and data switches. With Non-
Volatile memory, keep the information after the main power supply is interrupted.
The expansion slot on the motherboard allows for additional features that are not available directly from the motherboard itself.
Video card, network card, SAN and other equipment (
Storage Area Network)
Card and modem card.
A hard drive controller is also required to provide communication and transmission of data to the connected hard drive, so this usually requires a slot as well.
Since computer system manufacturers are always trying to produce products with a smaller footprint, low-key cards have been developed to reduce the space of the computer system chassis.
Each area of the entire system, such as DRAM, CPU, expansion card, and non-
The volatile memory requires a power supply and must be connected to the computer's power supply via a connector on the motherboard.
If all subsystems and components of a computer system are to run as a whole system, they must be synchronized from a common source, so some form of clock signal is required for this purpose. Most low-
The terminal system uses a single-phase clock from a single clock generator that generates a square wave signal at a constant frequency.
Single phase means that the signal is carried out on a copper line.
Some of the more complex systems will use 2 or even 4 phase clock signals to synchronize multiple subsystems or components.
The motherboard is an important component in modern personal computers and is a catalyst for providing connectivity and allowing more and more collaboration between Add-ons, subsystems and peripherals.
Many manufacturers make their own motherboards, but ATX is by far the most popular, with fewer professional chipset manufacturers, mainly AMD, Intel and Nvidia.
If you are building a PC or upgrading a PC from scratch and need a motherboard, here are some simple tips: Make sure the motherboard does fit in that situation.
Case manufacturers usually specify types such as ATX.
The hard drive controller is usually integrated with the motherboard, just make sure that the rated controller speed matches the speed of the hard drive of your choice.
Ensure compliance with the maximum amount of RAM specified by the board manufacturer.
Make sure the Motherboard has enough expansion slots to accommodate any suggested cards you think of, or choose a motherboard with multiple onboard features like USB, Ethernet, FireWire, and sound.
Bus Speed determines the overall performance of the system because it determines the speed at which data is sent to the central processor, and attention should be paid to selecting boards with sufficient bus speed to meet your performance needs.
