In the construction of digital community, the choice of cable is one of the most important links. At present, several schemes are: 1, twisted pair, 2 coaxial cable, 3, optical fiber. From the practical application, because the price factor of twisted-pair cable has advantages over the latter two kinds of cable, but bec

The UTP and unshielded FTP for category 5 and Category 6 copper cables have already reached a consensus in the industry. After the promulgation of the 10GBase-T standard, the battle for shielding and unblocking 10g copper cables is now in front of us. When more and more 10g copper cable products are available and more mature, are they shielded or unshielded? Debate stems from out-of-Line crosstalk Before the promulgation of the 10GBase-T standard, IEE

specific applications to test the quality of cable jackets. For details, see: CMP: Fill-level communication cable, which is the highest cable Safety Grade and has a perfect flame retardant capability with very low smoke and toxin emissions. According to UL's definition, a bundle of CMP cables must be self-extinguished when the fan is forced to burn in dense comb

Officer Liu said, "net silver" crime through the Trojan program remote control of your computer, even if the use of the bank's U-Shield also useless, will be criminals steal your bank card information, "because your computer has been controlled by criminals." ” In response to the "net silver" crime, Officer Liu gave a simple method, that is, when the use of net silver if suddenly the computer appears abnormal display (such as

The following are provided using the NETCTL Configuration tool:Demand:Tstation Management mouth for daily use. There is no gigabit swap. So add a piece of gigabit card. This card is for the purpose of data transmission.At present the main is weekly to T7 backup use. But because it is a direct connection. So each time it is each other up after setting the IP on each other. Today want to give tstation this mouth elan0 to do the configuration is not moving.T7 also makes a profile so that you can di

The simple query of this function solves the problem I have encountered. Learn a lot about the knowledge and implementation of the SYS file system for the Linux kernel. Thanks to the @win of the crowd for their hints. The network card has the function of carrier interception physically, when the network connection is complete or the network link is disconnected, the hardware of the NIC chip will automatically set the register mark bit to identify.
