What is a Motherboard What Function What are The Benefits of Motherboards?
what is motherboard
The motherboard is known by many names, such as motherboard, system board, logic board, or in some countries it is called mobo. It is an abbreviation for the motherboard.
A motherboard is an electronic circuit board that is a very important part of a computer. It is the motherboard that directs the connected devices to perform the commands. The motherboard is a circuit board that combines computer components such as sockets for the CPU (CPU) and main memory and permanent memory. with bios as firmware with slots to plug-in devices to connect other accessories It can be connected to both internal devices and external devices. The motherboard has continuously developed technology, which today has a form that is popularly used in personal computers is ATX (Advanced Technology Extension). The development period of the motherboard is as follows.
Currently, there are two types of standard motherboards in use: ATX and Mini-ITX. It is a small motherboard for smaller computers. This Mini-ITX motherboard is mostly for entertainment purposes.
PC/XT is a predecessor built by IBM.
AT (Advance Technology) got its name in the 386, but it's outdated with the ATX model.
ATX is the most popular model in use today.
ETX is used in embedded systems.
LPX designed by Western Digital BTX (Balanced Technology eXtended) is the next generation motherboard introduced by
Intel Mini-ITX (VIA Epia) designed by VIA
WTX (Workstation Technology eXtended) is a motherboard for large computing systems.
What does the motherboard do?
The function of a motherboard is like a community area and transport routes, and the motherboard's traffic control panel comes with a chipset that indicates the motherboard's model. The motherboard consists of a socket for inserting the CPU, each model is not the same, there are about 2 RAM slots, a BIOS chip (Bios) for checking peripheral devices / there is a slot for a video card called. The white AGP/slot is PCI, which includes a LAN card/SOUND card.
The motherboard has a socket to insert the CPU. Let's take a look at each socket for which CPU.
Socket 370 is a very old Socket using a CPU of Intel Celeron, Pentium, etc. This model will be released as an early version
Socket 478 is a socket used in intel Celeron D, Pentium 4 CPUs.
Socket 775 is a socket that has recently been released by Intel as a manufacturer. For use with new CPUs which this CPU model does not have a pin But there will be a pin on the motherboard instead.
The Motherboard Contains.
1. Chipset The chipset is the heart of the motherboard. This device's main function is to control various devices to work as needed. The chipset is composed of two chips, the System Controller chip, or AGPSET, or the North Bridge, which is the chip that controls the operation of the main high-speed devices. On the motherboard that contains the CPU The second level cache memory (SRAM), main memory (DRAM), AGP graphics bus, and the PCI bus and PCI to ISA Bridge or South Bridge chip act as interconnection devices between the PCI bus system and the PCI bus. other-equipment with lower operating speeds such as ISA bus systems, USB serial bus systems, IDE controller chips, ROM memory chips
The nature of the use will depend on the CPU. mainly used Each brand has different strengths and weaknesses.
2. BIOS ROM memory and battery backup. BIOS BIOS or CMOS (CMOS) is a type of memory chip used for storing data. and small programs needed to boot the computer system, CMOS chips require electrical power to store data at all times. It will come from the battery back up on the motherboard. (The backup battery looks like a blue can. or is a round, flat silver Inside contains a 3-volt lithium battery), but later the two chips were combined. And called the bios chip ROM alone. but later developed The new technology chip ROM is either EEPROM or E2PROM. You can both write and erase using special software. easily by yourself as we see today
3. Second level cache memory that acts like a memory and buffers for the CPU using the principle Working with devices at higher speeds wastes time go with waiting for the device with that low-speed work until the end Because the CPU has a very high operating speed. The CPU's need for information Wash one batch to process if there is no cache memory.
How do we know that the motherboard we are using? What Onboard devices are supported? If you want to know, we can easily find out. Look at the back of the case. There will be ports for connecting a mouse and keyboard, and if the motherboard comes with another Onboard device, there will be ports for that device such as Modem, Lan, VGA, Sound ports. can be plugged in and used immediately.
What are the benefits of motherboards?
As you know, the motherboard It's a very important component. The benefits of the motherboard are many together. The motherboard is the main circuit board for connecting and controlling various devices in the machine. If the motherboard is not of quality, it may cause different data and devices. It can be damaged if the motherboard is stable and of good quality. will make each workflow smoothly Every device will work without interruption. As a result, the service life of connected devices is also increased.
The continual development of motherboard designs and standards is to prevent weaknesses that must be avoided in most motherboards. The point to be most careful about is the heat. The reason why the current ATX (Advance Technology Extension) standard is used is that the CPU and devices are positioned to be able to cool themselves well.
