When I first bought the computer, everything is new, as long as the connection speed guaranteed, then the speed is very normal, but over time, the computer will be used more and more slowly, in the end is what causes of slowdowns of your computer?
Network cable problem leads to slower speeds we know, twisted-pair cable is made up of four pairs of wire tightly twisted together and according to strict rules, to reduce background noise and crosstalk effects. Meanwhile, T568A and T568B standards using only twisted pair lines 1, 2 and 3, 64 lines, of which 1, 2 for sending, 3, 6, used to receive, and 1 and 2 must be from a round, 3 and 6 must be from a wound. The only way to minimize crosstalk, and ensure data transmission. Do not follow the correct standards (T586A, and T586B), produced by cable, there is a big risk.
Performance: speed is very slow when you are just starting to use; another was begun on the speed to normal, but after some time, slow speed. The latter is evident in the desktop computer, but with a laptop to check net speed is shown as normal. Because they do not follow the correct standards produced by the slower speeds also caused by cable and network connection quality. General performance than a laptop of desktop computer's network adapter, so in Exchange Troubleshooting, using the laptop detects normal speed and network cable not manufactured according to the standards cannot be ruled out that a problem exists. We demanded that all T586A, T586B standards to suppress cable detection failure cannot be used in notebook computers instead of desktop computers.
Loop exists in the network causing slower speeds when the number of nodes of the network involved is not much, the structure is not very complex, that rarely happened. But in some of the more complex networks, often have an extra spare lines, such as accidentally even when composed. As the network cable from the hub to the computer room, from the two-compartment computer room to the computer. From Network Center also has a standby line connected directly to a computer room, if these few lines simultaneously connected, then loops, packets will constantly send and verify data, thus affecting the overall speed. This search is more difficult. To avoid this from happening, request we develop good habits when laying cable: cable marked with the clear label, where there are alternative line to do a record. When you suspect that there is such a failure occurs, usually through zoning analysis step by step way to exclude.
