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 cable standa

. Currently, Category 5 wires are more than Category 6 wires. The 3rd class line is commonly used for 10 Mbps Ethernet data and voice transmission in the LAN, and complies with the IEEE 10Base-T standard. 5th twisted pair wires currently have the largest LAN market, with a maximum rate of 100 Mbps, in line with the IEEE 3u 100Base-TX standard. The main difference between Category 5 and Category 5 is the application. Only two pairs of cables are used for transmission during use of Category 5 cab

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

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

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

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

exon (exon expressed region) is part of the eukaryotic gene, which is preserved after splicing (splicing) and can be expressed as a protein in the process of protein biosynthesis.Exon is the last gene sequence that appears in mature RNA, also known as the expression sequence. A nucleotide sequence that exists both in the original transcription product and in the mature RNA molecule. The term exon also refer
