perform heavy charge or discharge.3. Basic charging methods. The battery features are different, so the charging should be carried out according to the method specified in the manufacturer's manual. In standby mode, the phone also consumes a battery. For fast charging, you must first turn off the phone or take out the battery before charging.4. The memory battery should be deleted regularly because of its memory effect. The method is to completely discharge the battery,Then refill. Discharge ca

and total number of data centers are relatively large, most of the products purchased in batch are checked by warehouse receiving. The proportion of the tests is from 2% ~ 20%, which is closely related to the total number of purchased products, the contract inspection ratio of Party A, and the degree of attention of Party A on product quality. Of course, the customer is conducting Cable Testing, you must use a test instrument that supports the cable test standards in TIA 568B, such as the "DTX1

to be solved is how to judge a dot within the triangle, reference blog: http://www.cnblogs.com/graphics/archive/2010/08/05/1793393.htmlI used the 3rd method.Key code:dot* A4shapecorrect::morph (Triangle source, Triangle target, dot p) {dot a = Source.a, B = source.b, c = source.c;dot at = TARGET.A, BT = target.b, CT = target.c;if (p = = a) return new dot (At.x, At.y), if (p = = b) return new dot (bt.x, bt.y); if (p = = c) return new Dot (Ct.x, CT.Y); Line CP (c, p); Line AB (A, b);D ot* d = cp

Wav TO amr and easy adjustment of the volume, wavamr volume Let's talk about how to convert wav to amr. Wav is the easiest way to generate recording audio on PC, but the disadvantage is that the generated audio volume is relatively large. Amr is a mainstream audio playing format on mobile phones. Its advantage is that the audio is small in size and easy to transmit. The conversion method is very simple. There are two types of amr. Here we take nb as an example. First, you need to download openco

wired network. The second is the mobile design, that is, applications can only be moved on wireless networks. The third is security design, which includes two aspects: wireless network security and user identity security. The last is multi-service design, so that multiple applications can run. Pay attention to actual deployment What should I pay attention to when I understand the content and principles of wireless planning in actual deployment? Fluke

Some people think that IP phones are just another application running on the data network. However, imagine this situation: the quality of VoIP calls is getting worse and worse, and even the entire enterprise IP phone system stops running. Terrible? Pay attention to VoIP and add specialized VoIP tools for your network management platform. Recently, Network World has evaluated a series of emerging products, all of which can be attributed to VoIP analysis tools. They help VoIP network administrato

low unknown compatibility (with network card, connecting hardware) Good poor individual difference big flexibility (distance length) good poor service life is unknown the use of convenience is very poor unknown jumper structure mainly from the jumper cable conductor, Crystal Head, protective sets of these three aspects, the following first let us more intuitive look at the finished jumper and on-site production of the jumper in kind contrast (left is the finished jumper, the right is

Fluke network's distributed analyzer (OPV-WGA, hereinafter referred to as WGA) analyzes the distributed switching Environment Network with a new method, allowing users to view the entire layer-7 network in the most rapid and simple way as needed. WGA works with the network monitoring Console (NIS-OPV) and Protocol Analysis experts to easily monitor and analyze 10/100/M Ethernet Over the desktop. It can be installed locally or remotely on the network.W

So far, face dirt is the main cause of fiber failure. According to a survey commissioned by Fluke Networks by installer and dedicated network owner, dirty face is the top cause of fiber failure. It is estimated that 85% of Optical Fiber faults are caused by contamination of the optical fiber end face. Therefore, the end face must be checked and cleaned whenever necessary. It is equally important to check and clean the two ends of any connection, as po

process of the basic link includes the error of the test access line. The six types of standards are very strict, and the remaining margin is very small. Therefore, the error of the Test Line cannot be ignored. Most of the adapters currently available on the market are basic link adapters, for example, Fluke network's DSP-4000/4100/4300 Series Digital cable tester random mostly equipped with basic link adapters. During the test, the error may be high

The Online Network Monitoring Interface Box of fluke network can maximize the perspective of the Full Duplex switching LAN and WAN network, and minimize the link failure time. Provides single-port or multi-port configurations. The Online Network Monitoring Interface Box can access all network traffic, including physical errors, in both directions of the full-duplex link. They are fault tolerant and support dynamic insertion of Network Monitoring and A

BKJIA editing Note: for the performance evaluation of vswitches under normal circumstances, note the following: features, application-level QoS Assurance, VLAN support, network management, and link aggregation, supports VRRP. In addition to the first two aspects, we have used the Spirent Test Center's fault generation/analyzer with 24 10 GB Ethernet filtering CV modules and 10 gbase

Vital: This is the highest standard of Web page quality. Vital's web page is usually a formal website for a company or a person. For example, search "fluke", Www.111cn.net is vital Web page. Useful: This is the second highest standard of web pages. Useful's web page refers to a Web page that answers query questions correctly. In my opinion, this is why Wikipedia is always in the front line in many searches. Relevant: This is the median score. Releva

Testing tools are the means to realize automatic testing, and reasonable use of test tools can not only improve the ability of network diagnosis, but also bring convenience to network management. Generally speaking, network testing tools in a broad sense can be divided into physical cable tester, network running Simulation tool, Protocol analyzer, special network test equipment, consistency test tool of network protocol and Network application analysis and Testing tool. The following selection o

(2) Fluke launched the certification-grade optical cable tester Optifiber is a revolutionary concept, just like the introduction of digital DSP cable tester DSP-100. 3. Development of domestic WLAN in the 2003 From the operator's point of view, the diversification of access and charge of the solution, promote the popularization and development of WLAN. But then, on the demand of the transport and pe

setting, only the CPU usage is seen as 50%. Always uncomfortable. Think about how good it would be if it could support 8 of them. It's 8 times times the size of a single core. A moment of tinkering, or not. It seems that you can only open up to the same number of CPU cores as the worker. That doesn't matter, 4 times times 4 times times. Better than nothing The second problem is the variable that calls the other function inside the for loop. For the sake of convenience, I used a single global. B

force is the entire cable, otherwise the force is the cable and the connection of the metal part of the connector.In the cable wiring construction, the cable tension is bound. Generally 9 kg or so. Please confirm its pull with the cable supplier. Too much tension will damage the symmetry of the cable.Cabling System Testing ProcessCabling System testing is generally divided into three steps.Wiring construction personnel with the test, at this time only testing the cable, cable line method, lengt
