Poor network quality may occur due to the following: Network congestion Routers or other network equipment are overloaded with too much traffic. Wireless LAN interference A large number of wireless devices are connected to the access points. Faulty LAN cabling or connection A cable is defective or becomes damaged.
1 Diamond is an excellent electrical insulator, Graphite is a good conductor of electricity. 2  Diamond is the ultimate abrasive, Graphite is a very good lubricant. 3  Diamond is usually transparent, Graphite is opaque.  Diamond crystallizes in the Isometric system and graphite crystallizes in the hexagonal system.

Silver is the best metal conductor, but graphene is the best overall material at conducting electricity. Graphene consists of carbon atoms arranged in extremely thin sheets, and has the lowest electrical resistance of any commonly known material. Most of the best conductors of electricity are metals. The best conductors are silver, gold and copper, while the worst are mercury and certain alloys of stainless steel. As a general rule, elements with a single valence electron are better conductors than those with more.
