the download speed of 1/8, can be said to be international standards. At the same time, because of this limitation, a single ADSL line in general, the maximum rate is only 10Mbps, very few 24Mbps ADSL.Of course, with the development of the network, telephone line access ADSL generally less, most rural still use telephone line access, and urban areas are generally used LAN access, that is, the use of network cable access, although the transmission med

For example, adding adapter A and Adapter B, respectively, at both ends of the network, when B sends the frame to the gate A, a happens to also send a frame, when the signal occurs collision, and when B detects collision, the signal is actually The distance between two A and B has been gone. 2. To know for sure that the frame it just sent did

Its UNIX systemschanging Ethernet Media speed for AIXFirst you need to find out the device name of your Ethernet card. It should is ent0 if the machine had only 1 Ethernet card. Otherwise, it may be a higher number.You can determine the legal values for the media speed of the card by running the following command (where the value of the May is different if you have multiple Ethernet cards).lsattr -R -l ent0 -a media_speedIf This command results in the following error-lsattr: 0514-528 The "m

Only then will you know where to start testing the cables to isolate problematic terminals, disconnected connectors, or grounding loops. In the copper axis network, search in the same axis "T-head" and the end of the network card, in the UTP Network, continuous operation of the instrument diagram testing function, constantly twisting the terminal to identify contact with bad or

do not meet the standard of broadband data transmission, there may be some return noise, line crosstalk phenomenon, which will affect the data transmission. Comments: The author of the region only some of the schools closer to the city is equipped with ADSL. This way the cost of investment is very low, but also more stable, just feel the speed of general. Second, cable wired access Advantages: Cable Wired access technology is based on high-quality two-way cable television network, HFC (Hybri

But at that time, as the first homemade supercomputer, its 16 Intel 486DX processors and the 10Mbps Ethernet bus were a great feat. Beowulf was designed by the NASA contractor Don Becker and Thomas Sterling, the first "maker" supercomputer. Its "compute part" 486DX PC costs j

Symptom: A company intranet is a 100Mbps network that connects to the Internet via ADSL broadband. The ADSL modem is connected to the 10/100 Mbps switch, and the switch is then connected to the server. When the connection is good, the PPPoE protocol is not available to computers in the company intranet. Failure analysis and exclusion: according to the symptom analysis, the PPPoE protocol may not be able to find the ADSL signal under the Mbps network, because the PPPoE protocol generally support

the bridge mode can be contacted with modem manufacturers to obtain the operation method; You can also judge the computer to connect to the MODEM, and dial on the computer, after the successful dialing, you can surf the internet, If this is the case, it means that the modem works in bridging mode, which can eliminate this possibility.
