POJ 1064 Cable master (second answer) DescriptionInhabitants of the Wonderland have decided to hold a regional programming contest. the Judging Committee has volunteered and has promised to organize the most honest contest ever. it was decided to connect computers for the contestants using a "star" topology-I. e. connect them all to a single central hub. to organize a truly honest contest, the Head of the Judging Committee has decreed to place all con
Scroll Mandrel must be used for field testing of Multimode Optical Cables according to U. S. TIA/EIA-568B standards ). It can be used to verify whether the 62.5 m and 50 m Multimode Optical Cables support Gigabit or even 10-Gigabit Ethernet networks by using a common LED light source with a wide scattering area. High-level and low-level models Multi-mode optical fiber cables contain multiple optical paths at the same time. Some of these paths are in the "low-level" mode in the center of the opti
Regardless of the final minimum copper platform, the complexity of the encoding system is a major obstacle for source equipment manufacturers. For cable and connector personnel and physical layer equipment installers, the question is more about what restrictions will this bring to the cabling facilities and what installation and test parameters will be required. The Working Group has made a lot of discussions to solve the problem of external crosstalk
We know that the cable is the basis of the network, if you do not well identify the use of the cable, you will not become a qualified engineer.The BNC cable is the copper shaft cable that we use for CCTV, which is used today as a signal input/output probe in an oscilloscope, although the appearance and the traditional
Rules for making cable Heuristic to think of the last year now do network maintenance day, every day line, pinch line, sometimes a day pinch more than 100 network cable. Based on the discovery that many of the computer-born small partners are unfamiliar with the network cable, the following roughly literacy. Network cable
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 specific steps are as follows: 1, the realization of mobile phone and computer connection The first step is to open the mobile phone "USB debugging" switch. Click "Settings"-"Application"-"development tool" and check the USB debug switc
Silver" crime is not even customer magnetic stripe information need. 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

Links:http://poj.org/problem?id=1966Test Instructions: an undirected graph, n points, M edges, to find the vertex connectivity of this graph.idea: vertex connectivity, that is, the number of cut points in the minimum cut point set, the general method of finding the vertex connectivity of undirected graphs is to transform to the minimum cut of the network flow.Build diagram:(1) The original image of each point I split, split for I ' and I ', I ' to I ', an arc capacity of 1.(2) for edges present
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. If the c
Cable TV NetworkTime limit:3000ms 64bit IO Format:%lld %llu The point connectivity of undirected graphs is obtained, that is to say, to find the minimum cut of any two points.But considering s set and T set, the middle is connected by several edges, these edges are the smallest cuts of s to T, assuming that this is the answer, then finding that there is no need to enumerate all the points, but to fix a point, and enumerate another point to ensure that
Based on the continuous development and application of new technologies, such as cloud computing and IoT, network demand for bandwidth is increasing, especially in the cloud computing environment in the data center will be a large number of virtualization technology, thereby maximizing the utilization of server equipment, which requires a higher bandwidth cabling system to support the cloud Computing data Center network communication, 10G (Gigabit Ethernet) application has become the mainstream,
There are two types of network interfaces for a general home router: 1. Wan Port: The WAN port is the Internet connection, and the other part of it is connected to the Internet device, for example: The cat's network port, or the upper router's LAN port (Cascade) All users have access to the Internet via a WAN port. The average home router has only 1 WAN ports (some routers have multiple WAN ports, which are currently on the market), and are labeled with different colors, with letters labeled
Joint Index is a secondary index, the bottom of no data, fewer blocks, fast traversal. 7. General analysis, only T8 table (INNODB) in accordance with the primary key index sorting time is much, the rest is OK Time Sequencing Conclusion: InnoDB. Primary index > InnoDB. Secondary index > Mysiam The efficiency is nearly 30 times times worse, where is the problem? 1. The main reason, the order by ordering along the primary key, the query will spread a lot of blocks,
indexes frees the disk space that the index consumes. After you disable nonclustered indexes, all queries are the same as no indexes. Disabling a clustered index frees the space occupied by non-leaf layers in the index. After you disable a clustered index, the table cannot be queried and updated. Because disabling an index is accompanied by a space release, processing requires a small amount of processor time and log file IO. The primary reason to disable indexing is to save some disk space whe
