What tools do not use a network cable can easily achieve multiple computers synchronized Internet access 1, first of all, select one of the notebook computer as the host, the host needs to be normal with the network cable connection, that is, the normal Internet. Open the host's network connections, select Wireless network Connections, right-click on the Properties dialog box, under the General tab, doubl

First, the mobile phone data cable connected to the computer, mobile phone prompts "host no response" How to do? This is because you are using a computer connected to the USB interface wiring or chassis front USB interface, try to test the rear of the chassis USB interface. Second, the mobile phone connected to the computer, the choice of "data storage" mobile phone will prompt "another program is in use." This is because your phone uses the memory

Many times, we will encounter the data cable can not connect to the computer situation, many people do not know how to do. It doesn't matter, here, small weave to share peas pod solution cannot connect the computer problem through the data line, below can be helpful to everybody. Question one, if the mobile phone can not link to the computer through the data line? 1, poor data cable or USB power supply, t

1, data cable or USB power supply, this may be the purchase of the data line is not the original or the quality is very poor, at this time we can change the original data line or good quality data line can be resolved. 2, the pea clip is not the latest, we can upgrade the latest version of the pea clip, you can go to the official download 3, to see if the computer has installed security software, these software may not be allowed to link peas

1 when the power switch connector is connected to the power switch cable, first from the chassis panel line labeled "Power SW" two-pin plugs, are white and brown two colors, and then inserted in the motherboard labeled "PWR SW" or "RWR" on the words of the pin on it. 2 reset switch connectors are used for hot start of the computer. Connection, first find labeled "Reset SW" two-pin plug, is white and blue two colors, and then inserted in the motherboa

The internet cafes of penguin countries are connected by network cables to form a tree structure. Now that the winter is up, the heating sector lacks fuel, so they decide to dismantle some of the cables to make fuel. But now there are K penguins to surf the internet and others online games, so they need to put this K-Penguin into different room (two penguins in the same room will quarrel), and then remove some network cable, but need to ensure that ea

I. Optical Fiber1. OverviewThe optical fiber is similar to the coaxial cable, but there is no mesh shielding layer. The center is the glass core of light transmission. In multimode optical fiber, the core diameter is 15mm ~ 50mm, roughly equivalent to the hair width of a person. The diameter of the Single-Mode Optical Fiber Core is 8mm ~ 10mm. The outside of the core is surrounded by a glass envelope with a lower refractive index than the core to keep

Talking about Cable Modem broadband access technology and its maintenance when talking about Cable Modem broadband access technology and its maintenance, we need to first understand what Cable Modem?1 Cable Modem the concept Cable Modem is also known as a

Currently, cabling system installers and network technicians are still using older Cable Fault Locating tools based on analog technology that was just 40 years ago. Even tools that use these simulation technologies often identify cables incorrectly or cannot discover signals in common work environments, they are the only choice. This is the case until today. R D engineers of fluke networks have applied decades of specialized

A few years ago, people thought that the unshielded twisted pair copper cable had reached its limit in the fifth category of MHz. Many users and manufacturers turned their attention to the optical fiber and thought that the optical fiber is an inevitable transitional path for IT facilities. The optical fiber solves the disadvantages of unshielded twisted pair wires in various aspects: it has higher bandwidth, longer distance, higher security, complete

Several problems should be noticed in the connection of optical cable. 1. Note the depth of the knife when opening the optical cable. The key to open the outer sheath of optical cable is to master the depth of the cutting tool, otherwise it is easy to break the fiber. In the actual operation, should rotate the sheath cutting knife, while observing the incision,

The cable system is designed and constructed for the convenience of the landlord, but the landlord and the facility manager usually have no knowledge or measure of the interior of the room to ensure the proper design and installation of the cable system. General contractors and construction managers are generally not experts on telecommunication cables, nor can they take into account the best interests of t

main driving force of Wan Xiaotong Cable Ethernet is to reduce the cost of Ethernet network, for a wide range of implementation of Gigabit Ethernet, the use of optical fiber transmission solution has been proved to be too expensive, so based on the copper cable solutions can be developed and applied. Wan Xiaotong Cable Ethernet Recently, the IEEE is working on

A cable with a jack is found in the chassis, and the surface of the slot is marked with some English letters. This is the motherboard control line. In the lower right corner of the motherboard can be found in a row of pins, the needle is also printed next to some English instructions, this is the place to plug the control line. First step: Connect the Power switch control line. The power switch control line is indicated in English as either "powered

Printers are an indispensable office equipment for every company, and some families also buy printers, but how do they connect when they buy a printer? The printer interface also refers to the type of interface that is used between the printer and the computer, and the main interface types of the printer products currently on the market include common parallel interfaces, Professional serial port as well as the mainstream USB interface and is not a very common network port.
