The local area network is the individual computer or the terminal, uses the communication line to connect each other, follows certain agreement, carries on the information exchange, realizes the resource sharing. Among them, communication lines, that is, transmission medium commonly used: twisted-pair, coaxial cable, optical fiber and so on. From the cost-performance and maintainability, most LANs use unshielded twisted pair (utp-unshielded Twisted Pair) as the transmission medium to network. T

The back line is in recent years in DIY assembly computer, more often heard, belong to the DIYer of professional terminology. In simple terms, the back line is for the computer chassis, as long as the chassis and power support to go back line, in the installed time, it can be internal wire to achieve the most streamlined and tidy, not only beautiful appearance, late maintenance is also convenient, and also conducive to chassis cooling.

This is done by Signaltap II to help with Debug.IntroductionUse of the environment: Quartus II 8.0 + de2-70 (Cyclone II ep2c70f896c6n)When you actually use Signaltap II, you'll notice that

and small four-core insulated wire cores into three insulated wire cores with smaller cross-section, and symmetric the three core Cables into cables, for 6/10 kV Inverter Motor cables, the cable structure is different from that of 6/10 kV common power cables. The common power cables shield three insulated wire cores with copper tape and form cables, the dedicate

How do you do the word three-wire table? Sometimes when we write the paper back to use the three-wire table, because the three-tier table its form concise, functional, and easy to read, used by the people have said. So how does word make a three-wire table? What are the benefits of doing a three-wire watch? So small ma

One-wire Demo on the stm32f4 Discovery BoardSome of the devs at work were struggling to get their software talking to a Dallas 1-wire device. I remember doing 1-wire comms back on the 1990s, but I hadn ' t do any 1-wire lately and all of my old code is for Proces Sors I no longer had running. But I had a weekend free,

Abstract: two-wire smart instruments are widely used in a single instrument with simple application and low cost. However, two-wire circuits need to transmit both energy and high-precision signals, which makes signal isolation very difficult. This article introduces the basic working methods of two-wire circuits. Based on this, the shortcomings of the existing pa

Tools for making crystal head of wire Wire pliers (for connecting crystal Heads) In fact, the tool is very simple, on one, the production is also very simple mainly to pay attention to the Crystal Head model, now the most commonly used standard is: Tia/eai 568B, there is a tia/eai 568A their wiring slightly different, making crystal head first will be crystal head with a card down side, there are copper s

We may be unfamiliar with the practices and usage of twisted pair wires. For example, it is hard to remember how the standard wire head is implemented. It is also vague to know the cross Line (or direct line) used. Let's talk about some notes. Prerequisites 1. Twisted Pair pin position definition (the crystal head has no clip side, from left to right), as shown in table 1. For Table 1, we only need to remember two points: one is that only one, two, t

For example, 120 mm² calculation: 120*8.89 = 1066.8 kg/km 1 conductor usage: (Kg/Km) = d ^ 2*0.7854 * G * N * K1 * K2 * C D = copper wire diameter G = copper proportion N = bars K1 = copper wire twisting rate K2 = core wire twisting rate C = insulation core wire number 2 insulation usage: (Kg/Km) = (D ^ 2-d ^ 2) * 0.78

In product catalogs such as LAN switches, there is a "wire speed (Wire Speed)" In a project that represents device performance. such as "The realization of the wire-speed LAN switch", "support line speed to achieve high-performance" and so on, often in the promotion of product use, people think is the meaning of speed, but in fact really so? Today we'll take a lo

Still struggling to find a suitable wire record table, Old Wang shared his frequently used record table, let you one step in place, not to worry about the measurement results table that conforms to the closed full circle method wire record table calculation table, I put the corresponding images and brief descriptions in my measurement space.

Now so we can hear in the radio spectrum, it's time to explore the possibilities of broadcasting

Since the beginning of this winter, many regions in China have suffered a cold wave. Since March November, China's North suffered a blizzard, which brought significant losses and impacts to the national economy and people's lives. On December 24, the Central Meteorological Observatory issued an orange cold wave alarm, which said that from the 24 th to the 26 th, a strong cold air would once again attack northern, western, and some eastern parts of China. This indicates that the "Frozen" phenomen

In reality, wire control headphones produced by manufacturers of various brands cannot be used in a universal manner, and purchasing dedicated headphones is expensive. If there are idle wire control headphones on hand, as long as the interface is appropriate, it can be matched with a little change. Our common wire control headphones, regardless of the interface

How to quickly insert a three-wire table in the WORD2010, in fact, in the WORD2010, tabulation function is very powerful, rapid generation of three-wire table is very convenient. It takes two steps to generate a three-wire table in the WORD2010. First we need to insert a three-row table in the WORD2010 and insert the table in WORD2010 's Insert Ribbon Table tab.

: Copper medium is a kind of electric signal transmission medium which is widely used in computer network, there are two main twisted-pair and coaxial cable, now the newly built computer network is basically a twisted pair as the transmission medium Star topology network, and coaxial cable is gradually out of the computer network market, Currently the most widely used scene is the cable TV network that we are familiar with, and cable TV connection cable in home is fine coaxial cable. 1, twiste
