effectively prevent the static electricity to the computer hardware damage, I will introduce several methods. How to effectively avoid the N-way of electrostatic First, the computer chassis needs reliable grounding Some users respond, hand contact to the computer chassis, there will be shock paralysis feeling, this is because the chassis does not have a good grounding, static accumulation in

fails to pass the CRC checksum, the frame is considered distorted. By verifying that the frame is considered valid, the NIC receives it for local processing. Basic knowledge of the computer Factors affecting the work of network card Whether the NIC works correctly depends on the network card and its connected switching device settings and the interference caused by the network card working environment. such as signal interference, grounding interfe

full load operation of the Internet bar: After the first Test run, the equipment in the Internet café in batches to open, and gradually reached the full load of the Internet café power operation. It is best to run the whole load at more than 24 hours, in order to verify the true performance of the power wiring system. In the full load operation process, if the air switch automatically tripping or fuse is burned, please be sure to carefully check the reason. 3, Internet cafes overload operation

guarantee that the resistance of the copper foil on the board is zero, and that the access point is separated digitally from the analog ground in order to minimize the co-ground resistance of the digital ground and the analog ground.Second, the basic principles of digital and simulated ground treatment are as followsIf the simulated ground and the large area of the digital directly connected, will cause mutual interference. It's not a short connection. For low-frequency analog circuit, in addit

All over the country has been fully into the summer, and summer thunderstorm weather often give outdoor LED display steel frame structure to bring lightning hazards, see the following several lightning protection measures.　　(1) For the protection of Direct thunder, in the led electronic display (outdoor) support structure to install lightning rod, indoor full-color LED display or next to a tall building led electronic screen , you can not consider installing lightning rod.　　(2) against the steel

metal particles to exist between wires, the gap is reduced. Therefore, the designer should take this factor into consideration when considering the voltage. When the wiring density is low, the signal line spacing can be appropriately increased, and the signal lines with high and low levels of disparity should be as short as possible and increase the spacing. Shielding and grounding of printed wires:Public Ground Wires for printed wires should be arra

voltage, rated frequency, and rated power according to the operation conditions specified by the power adapter. Tag and usage instructionsMarking is an important information that instructs the user to correctly install and use, and is the most basic security content to ensure the security of the user's personal and property. Labels must be durable and eye-catching. When considering the durability of tags, the impact on tags during normal use should be taken into account. Products sold in Chin

1. Prevents load balancing and integrated isolation switch. (The isolating switch cannot be operated when the circuit breaker, load switch, and contactor are closed .) 2. Prevent misdivision, false combination of circuit breakers, load switches, and contactor. (Operations on the operated device can be performed only when the operation instructions correspond to the operated device) 3. Prevent the Grounding Switch from shutting down the circuit break

caused by the failure of the post, some technicians are advised to use a separate socket. Also some netizens believe that the "big cat" power quality is generally bad, anti-interference ability is particularly poor, especially for a long time to use a severe fever, resulting in equipment failure. Therefore, it is recommended to switch to high-quality power supply (only the price is more expensive). 3, the equipment (including the host) for good shielding and

ADSL off line involves many problems, including line fault (line interference), ADSL modem fault (fever, quality, compatibility), network card failure (slow speed, outdated driver) and so on. Operators and users should do the following routine inspection: ADSL telephone line connector is safe and reliable: whether away from the power cord and high-power electronic equipment, ADSL household line and separator between the installation of telephone extensions, fax machines, billing equipment, such

the possibility, especially web viruses and worms. If the virus destroys the ADSL-related components, there will be a cut-off phenomenon. If you can determine the damage and attack by the virus, but also occurs when the cut-off phenomenon should check the installed firewall, the sharing of Internet Proxy Server software, Internet acceleration software, etc., stop running this kind of software, then the Internet test, see whether the speed back to normal. If the internet is not stable, you can t

I recently worked on a project in the lab and used Android Bluetooth development. There are many pitfalls in this project, so I still hope to write down these things and share them with you, so I don't want to go on my own. Let's talk about the background. I am an APP that develops mobile phones and smart devices with Bluetooth (such as Bluetooth sphygmomanometer, blood glucose meter, and wristband. That is to say, there is no operation on the device

1. Start to put the wristband on a wrist.2. When you find yourself complaining, chatting, or criticizing, move the bracelet to another hand and start over.3. If you hear complaints from other people wearing a purple bracelet, you can point out that they should move the bracelet to another hand. But if you want to do this, move the bracelet first! Because you are complaining about them.4. Stick to it. It may take several months for you to achieve the g

. Specifically, the built-in news reading program, system security, and 40 TB cloud storage space are worth mentioning. Compared with miui 6.0, which focuses on improving the animation effect, flyme 4.0 is undoubtedly more changing. In fact, among the many third-party Android systems with in-depth customization, flyme 4.0 is outstanding. In addition, meizu's ambition is far more than that. It also wants to build a complete ecosystem. The corresponding means provided by it is to access smart hard
