In addition, in the T568A and T568B cable standards, the twisted pair wires only use four serial numbers: 1, 2, 3, and 6, among them, line 1 and line 2 are specifically used to send data information, and line 3 and line 6 are specifically used to receive data information, and the T568A production line standard

Then, the NIC's "network cable pulled out" is changed to "enabled ", configure according to the "ip" address provided by the network service provider to enable normal internet access. The NIC connected to "local connection 3" does not need to be configured. 2. Use another machine as the client, install a NIC on it, install the Windows 98 operating system

, because each wiring construction personnel's technical level is good and bad, this leads directly to those low quality, the technical level is not high the construction personnel to oneself request is not high, often can only satisfy oneself to arrange the network cable to meet only "pass" the minimum requirement, They simply think that the network cables they have arranged are qualified as long as they are able to pass. In fact, the arrangement and production of network cables Meet the standa

GenerallyExpress CONNECT: both ends are connected in t568b line order.Crossover line: one end is connected in t568a line Order and the other end is connected in t568b line order.

There are two connection standards for RJ45 twisted pair wires: Standard 568B: White orange -- 1, orange -- 2, white green -- 3, blue -- 4, white blue -- 5, green -- 6, white brown -- 7, brown -- 8 Standard 568A: white green -- 1, green -- 2, white orange -- 3, blue -- 4, white blue -- 5, orange -- 6, white brown -- 7, brown -- 8 Currently, the 568B standard is used in the network. 10 M Ethernet cables use, and 6 serial numbers to transmit data, while M Ethernet cables use, serial number

The TCP/IP model consists of the following layers and main functions: the application layer directly provides services for your application process. The transport layer is responsible for providing services for communication between two host processes. The Internet layer is responsible for providing basic data packet transmission functions so that each packet can reach the target host. The Network Interface Layer receives and transmits IP data packets, receives physical frames from the network,

Twisted pair has two methods, eia/tia568b standard and eia/tia568a standard.(1) Straight line: Both ends are connected in accordance with the T568B sequence standard, as shown below:B Standard: white/orange orange white/green blue white/blue green white/brown BrownA standard: white/orange orange white/green blue white/blue green white/brown Brown(2) Intersection line: A t568b line order standard connection,

need to transfer data through a hub or vswitch. However, when connecting two NICs, you cannot directly use the express Connect line, but you must use the cross-type network line. When creating a cross-type network line, you must use the T568A line sequence to connect one end to the other, the other end uses the T568B line sequence connection. If the crossover network cable is not created in accordance with

ISO/IEC 7498, which defines the 7-tier framework for network interconnection, the Open Systems Interconnect Reference Model (OSI model ).A switch is like a neighboring street, and a router is the intersection of a street. (The second layer of the switch , the data link layer, also has four layer, seven layer switch; the router works on the third layer).See (http://www.he.edu.cn/learn/wlxy/netlan/index.html)Crossover and direct-attached network cablesFirst, direct connection interconnectionBoth e

marked on the label, there is a standby line of the place to do a record. When such a failure occurs, it is generally used in a step-by-step approach to partition segmentation. Third, network cable problems caused by slow speed We know that twisted-pair wires are tightly twisted and together by four pairs of lines to reduce crosstalk and background noise. At the same time, only 1, 2 and 3, 64 lines of twisted pair are used in the T568A standard and

In the above links must establish a sound document, as part of the acceptance.(Excerpt from: David's wiring bulletin board)Common mistakes in line playingThe common error of the line is open, short circuit, reverse connection (two of a pair of lines crossed, such as 1 corresponding 2,2 corresponding 1). Another error is bridging, such as 1, 2 corresponds to 3, 6. The main causes of this error are two. One end of the cable uses the T568A
