, filtering out the user caused "harassment" of the spam message. But after all, there is no guarantee that users will be completely protected. It's also certain that there are occasional miscalculations. Therefore, the default settings are not entirely easy to use, if you want to make Kaspersky's message protection capabilities more powerful, users also need to set up the Kaspersky software function, according to their actual needs, to adjust it. Kaspersky's mail protection settings are locate

These two days to modify the network card driver to achieve 10/100/1000m adaptive, so the next PHY chip and EMAC driver to the compatibility of 10/100/1000m network environment, recorded here. Network device-side Data link layer is composed of MAC Chip and PHY chip, PHY chip based on the external network environment to complete the automatic negotiation and configuration, drive in accordance with the PHY state to configure the Mac to achieve PHY and Mac work with each other. Now the mainstream n

a straight line. Use the crossover line to cascade the switch through the normal port. Cascade of Switch Fibre ports Because the price of the switch fibre port is still very expensive, the fiber is used primarily for connecting between the core switch and the backbone switch, or for cascading between the backbone switches. It should be noted that the switch fibre ports are not stacked and can only be used for cascading. Cross-connect of fiber jumper More Wonderful content: http://www.biance

changing as each symbol changes. EVM is also very important for the performance of WCDMA transmitter, because it indicates the modulation quality of the transmitting signal. A large EVM value will result in poor detection accuracy, thus reducing the performance of the transceiver. Frequency error: The difference between the specified carrier frequency and the actual carrier frequency. Due to the adjacent channel interference and low quality detecti

. Hardware DesignThe hardware connection of the MCP2515 and s3c2416 is shown in Figure 3. If the hardware schematic diagram shows that the MCP2515 chip is connected to the s3c2416 chip SPI0, interrupted on GPF1, MCP2515 output connection sn65hvd230 can bus transceiver, sn65hvd230 is Texas Instruments produced by the 3.3V can transceiver. In order to save power and reduce the circuit volume, the logic level

ADSL Cat LED Description ADSL Cat indicator is an important tool to judge ADSL faults. Different brands of different models of cat led numbers vary. But they all have link lights, LAN lights and power lights. Link Light Status Description Link lamp for the cat and the local Dslam device connection indicator, usually link lights have a rhythm flashing, indicating ADSL data link is trying to sync, at this time the link is not connected. Under normal circumstances, ADSL cat after a minute of syn

The new version of Eggplant Express Computer version has increased the classic two transceiver mode, in this mode, in addition to supporting the file with the Android device to send and receive, while also supporting the computer (Windows system) and computer (Windows system) between the file transceiver, computer (Windows system) Send and receive files between iOS devices (note: Only pictures and music are

this time the link is not connected. Under normal circumstances, ADSL cat after a minute of synchronization process, after the success of the link lights often bright, some brand model cat link lamp has the role of the data transceiver led, will be flashing with data transmission. In the Internet, if the link lamp has a rhythm flashing, indicating that ADSL is not synchronized, then the network is in a state of interruption, in most cases, there is

standard for applications that have a frequency range between 2G to 10G Hertz. We can see that 802.16.1 is responsible for very high frequencies, and its work is at the forefront of these three groups. Because of its unique bandwidth, 802.16.1 is most likely to attract industry interest in the future. The role of the 802.16 wireless service is to establish a communication path between the user site and the core network, which can be a public telephone network or an Internet. The IEEE 802.16 s

worker thread (recall how the Java program is executed in the Tomcat thread, how the task is performed in the Dubbo worker thread), As a result, you can increase the number of worker threads by increasing the concurrency capability, and the main focus today is "how much of this model worker thread is set to maximum concurrency".Pure Asynchronous Threading ModelThere is no blocking anywhere, this threading model only needs to set a very small number of threads to achieve very high throughput, LI

Design IntroductionTraditional manual Office is unable to meet the needs of modern office, transceiver management system as to improve work efficiency, standardize Office system, enhance the transparency of office, realize the unified management of information and document resources, facilitate leadership decision-making, and gradually realize the paperless office of important tools, more and more people pay attention to. We choose b/s three-tier str

Help coal mine customers adjusted for many years terminal resistance, summed up some of the experience for everyone to reference, no reference theory, but are the result of practice. About the terminal resistor: We always remember can terminal to add 120 euro, but that is a short distance impedance matching results, if in the long-distance or add 120 kohm will be very harmful to the signal, because the can transceiver drive capacity is certain, trans

interface is also a two-wire interface, it is two lines through a complex logical relationship between the transmission of data, communication speed is not high, the program is also more complex to write. The general SCM system is mainly used to connect with small easy memory such as 24C02.SPI: High-speed synchronous serial port. All-in-line interface, independent transceiver, can be synchronizedUART: Universal asynchronous serial port. Two-way commu

the network port, from the SD card, start the application, the whole transplant process is smooth, unexpected smooth, I drop off the bottom transceiver function after the transplant, soon can use, but I am not satisfied with the "official boot" Serial transceiver is a blocking way, as if very backward, I use the LPC1788 on the non-blocking mode of receiving and sending. However, the official boot function

is high, and in the use of the process will inevitably bump, therefore, in the use of a certain period of time, the test of the performance of the mobile phone transceiver will appear to varying degrees of decline. Under the same test conditions, the test results for the use of the new mobile phone and the old one are likely to differ significantly, which will result in a different assessment if the assessment requirements are severe. When the DT roa

In the whole optical network, the backbone of the network generally uses quartz fiber network equipment to ensure the transmission distance. and between the Working Group and the workgroup, between the Working Group and the user, uses the plastic optical fiber equipment, realizes entire local area network uses the light to transmit the information. 1.

microwave relay communication long-distance microwave communication trunk can be transmitted through dozens of times to thousands of km can still maintain a high quality of communication. Microwave station equipment including antenna, receiver transmitter, modulator, multiplexing equipment and power equipment, automatic control equipment. In order to gather the wave to become beam, sent to the distance, generally using parabolic antenna, its focus can greatly increase the transmission distance
