PC using a type connector, socket DB-25 pass, including 17 signal lines and 8 line, signal lines are divided into 3 groups, control line 4, status line 5, data line 8. The printer uses a type-B connector, which is a 085inch pitch Champ connector

Hostapd introduction: To put it simply, hostapd can switch the wireless network adapter to the master mode and simulate the AP (which can be considered as a router) function, that is, the soft AP we call it ). As an AP authentication server, hostapd is responsible for controlling and managing the access and authentication of stations (usually a PC with a wireless network card. You can use hostapd to switch the wireless network adapter to the AP/master mode. By modifying the configuration file, y

In fact, it's supposed to be the best pattern recognition. In computer vision, there is a ICCV equivalent.

IEEE 802.11 was designed in the late 1990s s, when the powerful wireless network encryption technology as an effective weapon was strictly restricted by the United States. Wireless Network products are banned from being exported due to fear of cracking powerful encryption algorithms. However, two years later, the dynamic Wired Equivalent security mode was found to have serious disadvantages. However, the 1990s error should not be caused by wireless n

difficult to properly understand some basic knowledge. When you encounter difficulties or faults in use, you can solve them by yourself, not only saving time, but also learning a little knowledge. However, many people think that wireless routers can be used for plug-in! No need to set anything? Isn't it good? This is certainly the case for general applications, but if you encounter problems such as: Why is the overall suspension speed slow, and so on, will you be unable to start as a common con

1. Mixed wireless networks often fall off the line Failure phenomenon Use the Linksys WPC54G network card and Linksys WRT54G AP to build a wireless LAN that uses IEEE 802.11G protocols and a few 802.11B network adapters. The line is often dropped when using wrt54g for 54mb/s connections. Fault analysis In theory, the IEEE 802.11g protocol is backward-compatible with the 802.11B protocol, and devices usi

Overview: Media independent interface (media-independent interface), or media-independent interface, is the Ethernet industry standard defined by the IEEE-802.3. It includes a data interface and a management interface between MAC and PHY. Data interfaces include two independent channels used for the transmitter and receiver respectively. Each channel has its own data, clock, and control signal. The MII data interface requires a total of 16 signals. Th

address is defined by the Institute of Electrical and Electronic Engineers (IEEE). Assign an EUI-64 address to a network adapter, or derive it from an IEEE802 address. During the IPV6 stateless address autoconfiguration process and the link-local link-local address generated under the interface, the interface ID section is typically generated according to EUI-64 rules: that is, the next 64-bit portion of the IPV6 address 128-bit length.

~ 1500 bytes. · FCS-this field contains a 32-bit Cyclic Redundancy Check (Cyclic Redundancy Check, CRC) value to verify damaged frames. The initial Ethernet II frame format has some drawbacks. To allow conflict detection, 10 Mbits/s Ethernet requires the minimum group size to 64 bytes. This means that if the frame length does not reach the standard, 0 must be used to fill the short frame. Therefore, the upper-layer protocol must contain a "length" field to distinguish the actual data from the
