Let’s go back so far several items have been mentioned as being connected to the motherboard, they are the following hard disk drive which connect via the older IDE or the newer SATA interface cable, then the memory or RAM which is connected via the memory slot and then there’s the graphics card which is generally built-in or is connected via the graphics card slot which could be the now phase-out AGP slot or the newer PCIE slot. All the three system mentioned previously communicates with each other via the motherboard and also communicates with the central processing unit or CPU. The motherboard also serves as the manager of all different systems connected on it. The motherboard also facilitates the proper flow of data from one point to another. One important function of the motherboard is to regulate the flow of current from the power supply unit to all the different components that needs them. The power supply unit is also connected via the motherboard using several color coded wire where in each wire color correspond to a specific value of power that flows thru it.
Also other additional system that interacts with the motherboard are the sound card which processes information to be converted to sound and is play out via a speaker system. Another expansion system is the NIC controller which comes in two configurations. The first type is built-in NIC controller and the second is add-in card. The NIC stand for network interface card or controller, this system allows the computer to be connected to a network, or to the internet. The expansion NIC is also connected via the PCIE slot located next to the graphics card. Also all motherboard have external connector for external devices such the printer, mp3 player, Smartphone, external drive, flash drive, microphone, speaker and many other devices. As we can see the motherboard is the host for all the devices that can connected to the computer. Other devices can also use the external ports of a motherboard to charge their battery. This feature was not available before, but as technology evolves and develops the computer allows other devices such as smart phone and mp3 player to charge their battery via the usb ports.
One important feature of the computer motherboard is that there are no moving parts. All different systems are electronic there is no wear unlike parts that has a clear movable parts where the continuous movement through constant usage at a long period of time will eventually result in that parts succumbing to wear and tear. But since all components are small, to be exact micro in size or even smaller that power they consume less power compare to conventional devices which would eat a considerable amount of power. While wear and tear is not common to electronic component, power surges are common. These small electronic component when feed with the right amount of power will function correctly but if the power being feed increases dramatically at a given time then that electronic component is very susceptible power burn-out which will cause the main system to malfunction and eventually failure. Just like what I posted a couple of days ago regarding motherboard failure cause by blown-out capacitor, the same is true with IC based components.
Integrated circuit is the main components of all type of motherboard and much other electronic system. All integrated circuit consume certain amount of very low power from 4 volts DC to 15 volts DC. So if there is a power surge on the motherboard system most IC would not be able to withstand such a sudden increase in power and will always burn-out once the power flowing through is suddenly increased instantly. The main benefit of very small circuits is that a lot of system can be built and compacted which in turns would produce smaller system and greater efficiency in operation. Also the cost of building such system is very chip as well since free made smaller system is already working and linking them together is the only problem. A problem that be easily solve by proper design and configuration. So whenever we are giving importance to other components of the computer the motherboard should also be at the top or near the top of your list because it plays a very important function in your computer over-all performance.
