(1) Fast Ethernet: 2 - pair UTP Cat.

(2) Higher categories of UTP require more twists on each wire pair in the cable to minimize crosstalk at high transmission frequencies .

(3) A disadvantage of UTP is that it may be susceptible to radio and electrical frequency interference.

(4) There are many algorithms to solve UTP problems, such as integer programming, and so on. However, these algorithm optimization effection to large-scale complicated system is not nice.

(5) For one thing, the UTP cabling requirements were upped again to category 5e, and 1000BASE-T uses all four twisted pairs—in both directions at the same time.

(6) Disconnect the router from UTP cables ( not the power cable ).

(7) But UTP cabling does work as well and does not have to radiate(sentencedict.com), and avoids the potential for power line loops and is likely least expensive.

(8) Two types of twisted-pair cable are shielded twisted-pair (STP) and unshielded twisted pair (UTP).

(9) And both coax and category 3 UTP can handle the additional bandwidth.

(10) When the gigabit ethernet work on UTP, it must adopt the 4pairs UTP at the full duplex mode, and need to increase some new requirement of performance parameters return loss , NEXT, PSNEXT.

(11) The UTP Ethernet variants support an additional autoconfiguration protocol that allows two Ethernet systems to negotiate which speed to use, in full or half duplex mode.

(12) The interface used in the Fog class UTP, coaxial cable, microwave or fiber to achieve.

(13) UTP is used in a "star" configuration, in which all nodes connect to a central hub.

(14) UTP is an NP problem, It is required to satisfy the requirements of the five elements of the soft and hard constraints in a certain time and space.

(15) There are many other Fast Ethernet cabling specifications than 100BASE-TX over cat 5 UTP, but only 100BASE-TX became a mass market product. Sentencedict.com

(16) What are two advantages of using fiber-optic cabling instead of UTP? (Choose two.

(17) This limits the maximum frequency in the signal, allowing it to fit within the limitations of UTP cabling.

(18) A slight complication to this setup is that every UTP cable is also its own Ethernet segment.

(19) Gigabit Ethernet, supported on 4 pairs of category 5 unshielded twisted pair UTP cable, is of high cast performance.

(20) Then in view of the disadvantages of the traditional genetic algorithm for UTP, the diploid code was put forward and alternate evolution was used to optimize multi-targets one by one.
