how to splice cat5

I. LAN interface cable standards 10base-t: twisted pair cable, generally using RJ-45 connector; maximum effective transmission distance is 100 m from the hub, even high-quality 5 category twisted pair can only reach 150 m. The matching resistance is 120 Euro. 10base5: coarse coaxial cable with plug-in connector and baseband signal. The maximum supported length is 500 m and the maximum segment is 100. The matching resistance is 75 Euro. 10base2: thin coaxial cable. The connector uses the industr

damage has occurred. The cable cannot guarantee the cable performance. Minimum bending radius For the minimum bending radius, see the cable diameter. It is usually expressed in multiples of D (Cable diameter. The diameter of cat6 cables is generally greater than that of cat5 cables. Therefore, the actual radius of cat6 cables is generally greater than that used in cat5 cables. Comparison between cat5e an

pair wires as transmission media: 100Base-TX, 100Base-T2, and 100Base-T4. Among them: 100Base-T4 standard requires the use of all 4 pairs of lines for signal transmission, the other two standards only require 2 pairs of lines. The 100Base-TX standard is the most popular in Fast Ethernet. Therefore, when purchasing a m twisted pair, do not use a twisted pair with only two wires at a low cost. Category 3, category 4, Category 5, and Category 5 twisted pair wires are defined as 4 pairs in the US c

With the development of science and technology, the computer price is getting lower and lower, the performance is getting better and better, the transmission speed of LAN is getting faster and faster, and the transmission medium of LAN is also switched from coaxial cable to twisted pair wires and optical fiber, twisted Pair wires have evolved from CAT1, CAT3, and CAT5 to CAT5E, CAT6, CAT6A, and CAT7. Although the performance of twisted pair wires has

lanport status indicator shows no normal connection.

A. The status indicator of the NETCORE router lan interface corresponding to the physical connection error is abnormal) Solution: 1) check whether the network cable is strictly compliant with the

use cat5e unshielded twisted pair wires in horizontal wiring. Cat6 unshielded twisted pair wiresThe parameters of cat6 unshielded twisted pair have been greatly increased, and the bandwidth has been extended to MHz or higher. The shape and structure of cat6 twisted pair wires are different from those of cat5 or cat5, which not only increases the insulating cross skeleton, place the four pairs of twisted pa

present the domestic operator also has the 2M transmission line networking. Another type of Out-of-band management device and managed device is placed in the same network using dial-up and so on as backup. This kind of network mode, Out-of-band network management equipment is connected to the Operation network, if there is a fault, through dial-up access to Out-of-band network management equipment. The console server has several RS232 interfaces (up to 48) and is connected to the console inte

With the development of science and technology, the price of computer is getting lower, the performance is getting better, the transmission speed of LAN is more and more fast, and the transmission medium of LAN has shifted from coaxial cable to twisted pair and optical fiber, twisted-pair line from the initial CAT1, CAT3, CAT5 to the present CAT5e, CAT6 CAT7. Although the performance of twisted pair has been continuously improved, but there is a para

array position 10. If the value is white, the project at position 4-9 is undefined by default. 4. Conversion Method All objects have the toString (), toLocaleString (), and valueOf () methods. The same value is returned by calling the toString () and valueOf () Methods of the array. This will call the toString () method of each item of the array in the background to splice the final string. 1Var a = ["red", "blue", "black"];2Alert (a. toString () //

(1) = 10; Deq1 [2] = 12; Cout Put_deque (deq1, "deq1 "); // Remove an element from the front and back of the deq1 Sequence Deq1.pop _ front (); Deq1.pop _ back (); Cout Put_deque (deq1, "deq1 "); // Clear the 2nd elements in deq1 Deq1.erase (deq1.begin () + 1 ); Cout Put_deque (deq1, "deq1 "); // Assign values to deq2 and display them Deq2.assign (8, 1 ); Cout Put_deque (deq2, "deq2 "); } The above demonstrates how deque performs insert and delete operati

in the array• Sort (comparefunction) method:-The parameter is a method used to compare two elements.-If the parameter is omitted, use • Slice (START, end) method:-The new array is returned, which does not affect the old array.-Contains elements starting from subscript start to subscript end-1-If end is omitted, all elements starting from the subscript start to the end are included.-If the parameter is negative, it indicates the subscripts (I .e., the subscript is n + array. Length) of the array

items before the array: var arr = ['a','b'];arr.unshift(1,2);console.log(arr); // [1, 2, "a", "b"] In addition to the two methods, you can also use the splice () method to add array items to the array: var arr = ['a','b','c',1,2];arr.splice(2,0,'d','c','e');console.log(arr); // ["a", "b", "d", "c", "e", "c", 1, 2] In addition to the splice () method, you can also use the concat () method to add array item

String representation of the arrayThere are two ways to convert an array to a string: Join () and ToString (), both of which return a string containing all the elements of the array, separated by commas, and here are some examplesvar names = ["David", "Mike", "Cynthia", "Mike", "Jennifer"];var namestr = Names.joi

If the value is white, the project at position 4-9 is undefined by default. 4. Conversion Method All objects have the toString (), toLoc

back to forward). Figure 2 is the data organization form of list. One obvious difference from the previous two container classes is that they do not support random access. To access the items at a subscript in a table, the cycle starts from the header or the end of the table (close to the end of the table. The subscript budget operator [] is missing. At the same time, the list still contains basic functions such as erase (), begin (), end (), insert (), push_back (), and push_front, next we wil

B = object. Therefore, go to obj [array [I]! = Array [I] |, that is, obj [B]-> obj [Object]->! = B, so it is stored Obj [B] = B; that is, obj [Object] = B; overwrite the previous obj [Object] =; In this case, all objects will be stored with only the last object value. When considering objects, I will use the following method: The Code is as follows: For (var I = 0; I For (var j = I + 1; j If (temp [I] = temp [j]) {Temp. splice (j, 1 );J --;}}}Retur
