of front audio, with the front-facing audio actually connecting only 7 lines, which is the 7 lines in the figure above. At the pin end of the motherboard, we just need to know the definition of each root cuttings pin, and it's good to connect the front audio. Let's look at the definition of each pin on the motherboard: 1--mic in/mic (Microphone input) 2--GND (grounded) 3--

Introduction to regular expressions

Some new users are not very familiar with regular expressions. it is necessary to make a brief review here. If you are a regular expression expert, you do not need to look at this part. A regular expression is a string that describes a string set. For example, the regular expression "Mic *" describes all strings that contain "Mic" followed by zero or multiple characters. This regular expression of Mickey, M

serious security vulnerability in WEP, WiFi Federation has developed WPA and WPA2 to replace WEP. Where WPA implements the main part of 802.11i, it provides backward compatibility with existing hardware and is used as a transition from WEP to 802.11i. After that, WPA2 completed the entire IEEE 802.1i standard.WPA uses different authentication methods depending on the scenario, where the wpa-psk of a home or small office network does not require a dedicated authentication server, and all devices

A complete mobile phone Structure Design Process

start to build an internal structure. Vi. Structure Design To refine the structure, we should first start with the overall layout. I advocate that the overall structure should be well planned, that is, the upper and lower shell stop lines, the screw column and the main buckle structure should be well done to complete these three steps, the mobile phone framework is built. then follow the order from top to bottom, from top to ground to complete the detailed structure. From top to bottom means t

Board jumper connection method secrets

? Let's take a look.From the current market, we can see that the sorting of the front audio plug-in has become a fixed standard (such ). From the figure, we can see that there are a total of 9 pre-audio pins, But they occupy a total of 10 pin positions, and 8th pins are left blank.It is a typical frontend audio line. In fact, the frontend audio only needs to be connected to seven wires, that is, seven wires. On the pin end of the motherboard, we only need to understand the definition of each pin

key.After the sta passes 802.1x authentication, the AP will get the same session key as the STA, and the AP and STA will use the session key as the PMK (pairwise master key, for pre-shared keys, PSK is PMK ). Then the AP and sta through the EAPOL-KEY WPA four handshakes (4-way handshake) process ,.In this process, the AP and sta both confirm whether the other party holds the same PMK as their own. If they are inconsistent, the four handshakes fail. To ensure the integrity of the transmission, t
