The motherboard is one of the most fundamental components of a computer, and it features a variety of interfaces. Today, I will introduce the functions of each interface for those who are not very familiar with this aspect.
First, let’s look at the side interfaces, as shown in the image:

Description of commonly used interfaces:
SATA hard drive interface: This is the Serial ATA, a new type of hard drive interface that has been upgraded from PATA, significantly improving transmission speed.
HDMI interface: This is the graphics card slot, primarily designed to provide high-performance graphics acceleration support for gaming enthusiasts.
CPU socket: The CPU interface, also known as the “central processing unit,” is where the CPU is inserted, which is the most important device in a computer.
Memory slots: This interface is mainly used for expanding memory; motherboards generally have two memory slots. Memory is akin to a phone’s operating memory.
Main power connector: This is the motherboard power supply connector, which is mostly a universal 20+4 pin supply located in the middle of the long edge of the motherboard and is quite large.
Auxiliary power connector: Also called the CPU power connector, it is used to supply power to the CPU. Currently, most CPUs are powered by an 8-pin connector, while some lower-end motherboards may use the older 4-pin connector, which are compatible with each other.
The above are explanations of the commonly used interfaces on motherboards. If you find it useful, remember to give it a thumbs up!
