Recently, someone often mentions how Exchange's multiple domain names are implemented, simply collating a document and communicating with everyone. By default, the default policy for Exchange Server 2010 is to send and receive mail using the same

Abstract: This paper discusses how to use the serial port with FIFO to reduce the number of received interrupts, and gives the frame packing method through a custom communication protocol format, and then introduces a special serial port data

How does a laptop use a wireless mouse? Wireless mouse believe that many friends are not unfamiliar, the general notebook users to pursue simplicity, more like the use of wireless mouse. The biggest bright spot is that it eliminates the need to use the computer U interface, with the addition of a data line tail, to make the computer desktop more concise. The following small series on the detailed introduction of wireless mouse and notebook connection using the tutorial. 　　How to use

ObjectiveIn the past few weeks, I have investigated and researched the security of GSM in many aspects, such as the loopholes in GSM communication protocol. In addition, I have a security audit of the most widely used BTS software in the world today. In this article, I'll show you a few of the vulnerabilities I've found in this open source product that will allow an attacker to invade the base station transceiver (BTS) and remotely control its

For example, /Usr/X11R6/bin/xmodmap/usr/share/xmodmap. fr Set the keyboard in your X system to a French keyboard. 　　 After the/etc/sysconfig/keyboard file is correctly configured, the configuration program of X system configures the section on keyboard configuration in X according to the information in this file. If the content of this file is incorrect or the file does not exist, X system cannot be started and configured. 　　 　　 2. Configure the mouse 　　 2.1 Basic mouse informatio

characteristic impedance Z0 of the transmission line cable. The RS-485 is recommended to use a 120 Z0 cable, so each end of the cable is usually used 120 resistance for end-to-end connection. Figure 4: RS-485 end-to-end using common mode noise filter. Applications in a noisy environment often use two RC low-pass filters to replace these 120 resistors to enhance the filtering of common-mode noise (see figure 4 ). It is worth noting that the resistance values of the two filters should be equal

LinuxThe configuration process of a device is to use this information to configure the driver and working method of the device after detecting the device type and current working parameters of the device, for device detection process, see how to implement automatic hardware detection in Linux). To complete such a task, you need to do the following: First, a detailed device information file is required, which describes the device ID, the device driver corresponding to the device ID, and the devic

). Note that the IP addresses of the two APS must be in the same CIDR Block and the same channel can be used to achieve wireless connection and resource sharing between the two wired LAN networks, or expand the wired network. It should be noted that both APs adopt oriented antennas. Opinion 2: Use optical fiber Many netizens have agreed to this solution, because the current price of fiber optics is also more than 10 pieces per meter, and the cost of pulling fiber cables between two points is no

termination resistor.Figure 2 shows an example of the SN75LBC176A transceiver Unit load calculation. Because the device integrates the drive and receiver together to form the transceiver (that is, the driver output and receiver inputs are connected to the same bus), it is difficult to obtain the drive leakage current and receiver input current separately. For ease of calculation, the receiver input impedan

What makes good: Germany as a large machinery manufacturing country, its mechanical keyboard is more well-known, especially a lot of friends familiar with the Cherry, is a 1953 since the establishment of the old brand, which in the mechanical keyboard manufacturing technology far more than other brands. The following is to introduce the most popular mechanical keyboard, the best sales of the top ten brands. 1, Thunder Snake Mechanical Keyboard 2, Cherry Mechanical keyboard 3.

the port specification when purchasing the device. You only need to select the GBIC corresponding to the required transmission interface, and it is easy to make adjustments as needed. The current GBIC has a Small version (Small Form-factor Pluggable, SFP), also known as mini GBIC (mini GBIC ), The size is about half of the original size, which not only saves costs, but also doubles the port density of network devices. Term 3 Small encapsulation pluggable
