RJ11 the definition and standards of the relevant provisions. 　　 RJ11 usually refers to the 6-position (6-pin) modular jack or plug. The connectors do not have international standards and are mentioned in the generic cabling standard. Also, this name is often used in the 4-pin version of the modular connector, causing confusion. 　　 In the generic cabling standard, there is no separate mention of '

line to connect. RJ45 Type Cable Plug RJ45-type network cable plug also known as Crystal Head, a total of eight cores made, widely used in LAN and ADSL broadband Internet users of network equipment between networks (called five-type line or twisted pair) of the connection. The difference between RJ45 and RJ11 Different standards, different sizes. Because the size of the two is different (RJ11 is

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
