Preface:Wi-Fi has become increasingly familiar to smart phones, and the design of built-in Wi-Fi network cards on the motherboard is becoming more and more popular, however, some players may still think about the "Wi-Fi network card = Nic connected to wireless networks, I don't need it when using wired network". So let's talk about it today, what kind of functions can be achieved by the self-built Wi-Fi network card in the PC.

The most common SATA solid-state hard drive installation method
When a new solid-state drive is installed, many new cases are now designed with solid-state hard disk positions, especially when the smaller SATA solid-state drives are installed on traditional mechanical hard disk positions. Therefore, we recommend that you choose some of the 2012 production of motherboards, in order to better install solid-state drives. But if the 2.5-inch SSD is the same size as the traditional ha
