What does the motherboard structure mean and how to choose?

Motherboard structures are divided into AT, baby-at, ATX, micro ATX, LPX, nlx, flex ATX, eatx, WATX, and BTX. Among them, AT and BABY-AT are old motherboard structures many years ago, which have now been eliminated; The LPX, NLX, and Flex ATX are variants of ATX, which are mostly seen in foreign brand machines, but are not rare in China; EATX and WATX are mostly used in server workstation motherboards; ATX is the most common motherboard structure on the market, with many expansion slots, and the number of PCI slots is 4-6, and most motherboards adopt this structure; Micro ATX, also known as Mini ATX, is a simplified version of the ATX structure, which is often referred to as a "small board", with fewer expansion slots, and the number of PCI slots is 3 or less, mostly used in brand machines and equipped with small chassis; BTX, on the other hand, is the latest generation of motherboard architecture developed by Intel.

Micro ATX motherboards reduce the number of expansion slots to 3-4 and DIMM slots to 2-3, reducing the width of the motherboard horizontally, reducing the total area by about square inches, making it more compact than ATX standard motherboards. According to the Micro ATX standard, graphics and audio processing should also be integrated on the board. At present, many brands of motherboards use the Micro ATX standard, and Micro ATX motherboards are often seen in the DIY market.

Generally, if you do an assembly machine, you can use a large board, after all, you don't need to pursue the chassis is too small, and the expansion slot of the large board is larger than the small version.

It also depends on the chassis of the computer you want to build and the performance you are looking for.

Common motherboard structures are as follows:

1.ATX (Advanced Technology Extended): ATX is one of the most common motherboard structures and is suitable for most desktop computers.

It has a standard size (305mm x 244mm) and a fixed location for mounting processors, memory slots, expansion slots, and other major components.

2.Micro ATX: The Micro ATX is a smaller-sized motherboard structure for situations where you need to build a small or compact computer system.

Despite their small size, the Micro ATX main can still have a certain number of expansion slots and interfaces.

3.Mini ITX: Mini ITX is a smaller form factor motherboard structure for computer systems that require a very small footprint, such as a center or laptop.

It typically has only one expansion slot and is suitable for low-power and power-saving applications.

4.EATX (Extended ATX): EATX is a larger motherboard structure that is typically used in high-performance and workstation-level computer systems.

In addition to these common motherboard structures, there are also special-purpose constructions such as BTX (Balanced Technology Extended) and ITX series (e.g., Nano ITX, Pico ITX, etc.) that are designed for specific needs and applications.

Different motherboard architectures vary in size, number of expansion slots, interfaces, and power management, and the choice of motherboard should be based on individual needs and budget. Also, pay attention to the motherboard's compatibility with other hardware components to ensure that they work together and operate effectively.

1. Motherboard, also known as motherboard, systembourd and motherboard; It is installed in the chassis and is one of the most basic and important components of the microcomputer.

2. The motherboard is generally a rectangular circuit board, on which the main circuit system of the computer is installed, generally including BIOS chips, IO control chips, keyboard and panel control switch interfaces, indicator plugs, expansion slots, DC power supply connectors of the motherboard and plug-in cards, etc. Another feature of the motherboard is that it adopts an open structure.

3. Most of the motherboards have 6-8 expansion slots for the control card (adapter) of PC peripherals. By replacing these plug-in cards, the corresponding subsystems of the microcomputer can be partially upgraded, so that manufacturers and users have greater flexibility in configuring models.

4. In short, the motherboard plays a pivotal role in the entire microcomputer system. It can be said that the type and grade of the motherboard determine the type and grade of the entire microcomputer system, and the performance of the motherboard affects the performance of the entire microcomputer system.

Motherboard (English: motherboard, mainboard, referred to as mobo), also known as motherboard, system board, logic board, motherboard, bottom board, etc., is the center or main circuit board of complex electronic systems such as electronic computers, and the computer is a modern intelligent electronic device that can automatically and high-speed a large number of numerical calculations and various information processing according to the pre-stored program.

And because it works in a way that is very similar to the human thought process, it is also called a "computer".

The plane of the motherboard is a PCB printed circuit board, and on top of the circuit board, there are staggered circuit wiring; On top of that, there are the angular components: sockets, chips, resistors, capacitors, etc. When the host is powered on, the current will pass through the CPU, north-south bridge chip, memory slot, AGP slot, PCI slot, IDE interface, and serial, parallel, and PS2 ports on the edge of the motherboard.

Subsequently, the motherboard will identify the hardware based on the BIOS (Basic Input and Output System) and enter the operating system to perform the functions that support the operation of the system platform.

Board, also known as motherboard, system board, logic board, motherboard, bottom board, etc., is the center or main circuit board that constitutes a complex electronic system such as an electronic computer.

The main function is to make the various components of the computer have a connection, simply put, to connect the power supply with various external chips and its own integrated chips.

The CPU is a very large-scale integrated circuit, which is the computing core and control core (controlunit) of a computer. Its function is mainly to interpret computer instructions as well as process data in computer software. The CPU is installed on the motherboard, and the motherboard can be seen as the body, while the CPU is the heart.

The role of the motherboard

1. Integrate various important hardware devices

In order to enable the various hardware devices of the computer to transmit information and communicate with each other, the motherboard provides them with a variety of sockets suitable for themselves, therefore, the sockets on the motherboard will have CPU, graphics card, sound card, communication card, network card and so on. The motherboard can realize the information exchange and connection between them, and make information feedback on related operations.

2. Provide power for various hardware devices

The components on the motherboard, from the CPU to the hard drive, all need power to work, otherwise they are just a bunch of decorations. And when they are connected to the motherboard, the motherboard can provide them with the right amount of power.

When the user presses the power button of the computer, the power circuit and the power supply circuit can replace the electrical energy into the electrical energy suitable for each device, and promote them to work normally, and respond to the user's instructions in time. In addition, the motherboard of the laptop is also connected to the power supply, which can replenish the power supply of the notebook.
