, but rather a straight line, that is, the line sequence at both ends of the jumper is identical, but it does not mean that as long as the line sequence is the same, for the 100Mbps network uses 100Mbps Exchange method, Refer to the previous chapter of this tutorial for details. One more note is that the cascade between the hub devices is usually done through a cascading port, and that the interconnection between routers and hubs is done through a normal port. In addition, the router and hub dev

Topic Links:ah haha, dot me dot MeTest Instructions:A region of the Arctic has n villages (1≤n≤500), each of which is represented by a pair of integers (x, y), of which 0≤x, y≤10000. In order to strengthen linkages, it was decided to establish communication networks between villages. The communication tool can be a radio transceiver, or it can be a satellite device. All villages can have a radio transceiver

transceiver lamp "Normal", the user is God, I believe you once, but still not pass ah, suspicion is the user firewall or internal network problems, let users restart equipment, and then contact the user. The phone rang again, looking for someone, OK! Give a turn, just hang up the phone, telecommunications pass to the phone, ask us to do not network export access, I said do not need, this brother really dedicated, have to grind with me, I am anxious!!

; 　 3, as shown in the following illustration, the pop-up data will lose the dialog box, further emphasizing the consequences of this deletion. If you confirm that the data has been backed up or that no data is needed for backup, click the "Confirm" button to continue the partition deletion operation; 　 4, the following figure shows a partition after the deletion of the state, part of the disk into unallocated space (as shown in the red box);

1. Preface According to our current requirements, we have not enough disk space for the previously planned GB. Here we will demonstrate the resizing of The XFS file system. Because I am using KVM, we will also demonstrate the KVM resizing method.2. KVM disk resizing Before resizing, you must back up the data or take snapshots to avoid data corruption. [[Email protected] img] # qemu-IMG info c7_data_g2.raw # The modification is complete. You need to restart the KVM virtual machine to take effect

capacity forwarding characteristics. Data center switch must support Gaomi million card, that is, 48 million gigabit board, in order to enable 48 million Gigabit board can be forwarded across the line, data center switches can only use Clos distributed Exchange architecture. In addition, with the popularization of 40G and 100G, support 8-port 40G Board and 4-port 100G card is also gradually commercial, da

40g/100g era (the standard was released in June 2010, the technology has matured), we have no reason not to believe the arrival of the Wan Xiaotong cable era. In fact, cabling system, as an information and communication infrastructure, should take into account the development law of the network in line with Moore's law. For the data center, from domestic and foreign standards (Ansi/tia 942, EN 50173-5, ISO/IEC 24764, GB 50174-2008) are required to m

plan and construction have been replaced by the fussy of project validation. Unlike the voice-centred networks of the past, the next generation network will be a data-core fusion network. The China Network Communication (Holdings) Co., Ltd., which was born in the tide of telecom reform, was fortunate to be IP/WDM as the Technology Foundation and business platform of the network, and built a backbone network with 40G bandwidth, which lay a good found

Many computer users for the computer hard disk integer partition calculation method is not very understanding, therefore, today's small series to share about the hard disk integer partition calculation method knowledge, they include: Hard disk integer partition of the general calculation method and hard disk partition integer g calculation formula. Hope everyone will like it! Computer hard disk Hard disk Integer partition calculation method general algorithm: Partition size = (partition s

stream that the computer can recognize). Assuming that the PC uses a hundred gigabit NIC, the delivery speed is 100Mbps, so the calculated delivery time is: 800Mbit/(100MBIT/S) = 8s. The other two exchange nodes A and B, we assume that they are the city's metropolitan area network top-level node, and they directly through the cable access to the national backbone node, the backbone node bandwidth assumption of 40G, then 100MB files through the backbo

servers, switches and active devices, integrated wiring provides the highest return on investment (ROI), the integrated wiring in its life cycle (10-15 years) to support at least 2~3 generation of network switching equipment upgrades, 3~5 PC hardware upgrades. Moreover, as an important part of the physical infrastructure of data center, the integrated cabling plays an irreplaceable role in the reliable operation of the data center. Three key words for data center cabling Small investment, big

Vro interfaces are very important for network connection and routing functions. Here we will give a comprehensive explanation of vro interfaces and connection knowledge. A vro has powerful network connection and routing functions. It can be physically connected to a variety of different networks, which makes the router interface technology very complex, the more high-end router interfaces there are, the more network types it can connect. Vro ports include LAN ports, WAN ports, and configuration

The new-generation ADSL access technology supports up to four bearer channels and four delay channels, while the first-generation ADSL supports up to three bearer channels and two delay channels ). You can configure the frame structure latency and bit error rate (BER. The first generation of ADSL access technology has a fixed error code of 10. Because the BER is fixed, the line must maintain this BER indicator from start to end. Once the BER is greater than 10, the speed

proprietary wireless protocol developed wireless products. 2.4GHz type of wireless key mouse, generally plug in the computer's USB interface adapter, mouse and keyboard powered by the battery.2. Basic principles of wireless key mouseThe main difference between the wireless mouse and the Wired mouse is the way the signal is transmitted. Wired mouse uses wires to transmit information, while wireless keyboards use radio to transmit information. The early wireless keyboards used 27MHz bands, and th
