the construction of cable wiring, the tension of the cable is limited, generally about 9 kg. Confirm the tension with the cable supplier. Excessive tension will damage the symmetry of the cable pair. 2. Standardized cabling skills Some construction workers do not follow the 568A or 568B threading techniques when creating a line. Instead, they use the lines 1 and 2 to draw white and orange lines, lines 3 and 4 are white and green, lines 5 and 6 are white and blue, and lines 7 and 8 are white and

see of the beholder;Interface is a very important concept in object-oriented, we do not talk about object-oriented interface, in fact, the interface in our daily life everywhere, such as water pipes, gas valves, TV plugs and so on, in the object-oriented interface concept is actually similar to these. Why should we advocate the development of object-oriented software, I think is the way we develop completely can imitate the nature of the survival of
