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.
Non-metals have a variety of properties, but very few are good conductors of electricity. Graphite (a form of carbon) is a rare example of a non-metal that conducts electricity very well.Many non-metals have a low melting and boiling point.etals tend to have similar properties. They are always good conductors of electricity, and they usually share these properties: 1  high melting point. 2  good conductors of heat. 3  malleable (can be beaten into shape). 4  shiny when cut. 5  ductile (can be pulled into wires).
