PHP Export CSV format data implementation:First define a string to store the content, for example$exportdata = ' rule 111, Rule 222, 222, gauge 222, take 2222, rule 1, Rule 2, Rule 3, match characters, set time, validity '. \ n "; Then a foreach loop is performed on the array that needs to save the CSV, for example Copy Code code as follows: if (!empty ($lists)) { foreach ($lists as $key => $value) { $time = Date ("Y-m-d_h:i:s", $value

The specification of the USB connector has different meanings in different states. For example: In the United States, it is AWG is the United States of the cable standard (American Wire gauge), high-speed signal transmission, transmission line skin effect is the biggest difference. Maximum Skin frequency: 26AWG 107KHz 30AWG 270KHz For ordinary users, 30AWG means low power consumption under the same transmission speed, For ordinary users, the data

its "Instructions" (see section 5.9), which is used to measure and control the total rate of all the flow table item collections that are bound to it. Multiple "gauges" can be used in the same flow table, but are used in disjoint flow table item collections (that is, the stream table entries do not match to the same packet). Multiple flow table entries can also be used on the same packet aggregation, as long as the meter is used in the next flow table that processes this packet collection. Each

special material that gives it incomparable advantages over cables: High bandwidth and high transmission capacity: because the carrier is light in the optical fiber transmission system and the optical frequency is high, the bandwidth and transmission capacity are high. Strong anti-electromagnetic interference: Because the optical fiber transmits a beam, it is highly resistant to electromagnetic interference. Even if exposed to V or even v strong electromagnetic interference, it will not be affe

common cascade use and GBIC modules for stacking Ethernet switches. Cascade GBIC Module The GBIC modules used for Cascade are divided into four types: one is 1000Base-TGBIC module, which is applicable to cat5e or cat6 twisted pair wires with a maximum transmission distance of 100 meters; the other is 1000Base-SXGBIC module, suitable for Multimode multi-fiber (MMF), with a maximum transmission distance of 500 meters. 3. 1000Base-LX/LHGBIC module, appl

When the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways to connect vswitches: Stack and cascade. 1. GBIC and SFP 1) GBIC Cisco GBICGigaStack Gigabit Interface Converter) is a common and low-cost Gigabit Ethernet stack module that provides high-speed connections between Cisco sw

ground the ground, so that the screen itself becomes the biggest interference source, resulting in far worse performance than unshielded twisted pair UTP. Therefore, unless otherwise required, only unshielded twisted pair wires are used in the Integrated Wiring System. As a low-cost and high-performance transmission medium, twisted pair wires are widely used in horizontal cabling in integrated cabling systems. Twisted Pair wires are cost-effective, reliable, and easy to maintain. They provide t

in this period have better opportunities than any other time. Therefore, they are pursuing product innovation, technology, user experience, and other challenges, it is precisely what these smart hardware manufacturers are currently trying to solve. However, the competition between technology and experience is also becoming the focus of most vendors. Huawei honor 6 mobile phones are on the ultimate path in this regard. This flagship host launched by Huawei glory in 2014 uses the blockbuster 8-c

resistance, attenuation, and near-end crosstalk loss, cat5th and cat6 twisted pair wires also have some differences in the test parameters.Propagation latencyThe propagation delay is the extended time of the propagation signal. When channel and basic link propagation are determined, the transmission latency of the connected hardware cannot exceed 2.5ns within the range of 1 MHz to MHz. The maximum propagation latency of all channels cannot exceed 555

costs. Compare multiple schemes with the owner's responsibility, and adopt the best cost-effective and reasonable schemes.Advanced-the use of advanced and mature international technologies enables the system design to be built on a high starting point. The system architecture and the selected equipment should have an advanced international level and have development potential, on the Rise. The design of the system is advanced, the technical starting point is high, and the life cycle is long. Th

interruption time when fixing faults, responds quickly to a scheduled MAC. Composition of Integrated Wiring real-time smart management system Traditional network connections include the connection from the switch port to the distribution frame port, the connection from the distribution frame port to the client port, and the connection from the client port to the computer and telephone of the terminal device ). Generally, the network connection from the distribution frame port to the client port

this basis becomes even more uncertain. Therefore, the most basic condition for safe network operation is to ensure the reliability and effectiveness of the transmission media, and to ensure the high performance of the components connected to the network and the good matching between the components, minimize information loss and provide sufficient transmission capacity to meet application requirements today and tomorrow.

materials and printing clearly, and in most cases there are anti-counterfeit labels outside the carton. 2. Work on twisted pair case. The insulation skin of twisted pair wires should contain information such as the place of origin, implementation standard, product category, and cable length. Cat5 is the identification of Category 5, cat5e is the identification of Category 5, and cat6 is the identification of category 6 ".Products with uppercase lett

) Frequency and signal-to-noise ratio can be divided into 3 categories, 4 categories, 5 categories, and 5 categories. Currently, cat6 and cat7 lines are used in many places. There are at least three types of computer network communication. The following lists various line descriptions: Class 1: Mainly used for voice transmission (class 1 standard is mainly used for telephone cables before the beginning of 1980s), not for data transmission. Level 2

setting one to ten information points exist, the information outlet module for cable and optical cable backup is reserved. Because the user nature of a building is different, the functional requirements are different from the actual needs, the number of information points cannot be determined only by the office building model, in particular, demand analysis should be strengthened when private buildings (such as telecommunications, finance, stadiums, museums, and other buildings) and computer ne
