A local area network (LAN) is a network that connects computers and devices in a limited geographical area such as a home, school, office building, or closely positioned group of buildings. Each computer or device on the network is a node.
Silicone rubber is an elastomer (rubber-like material) composed of silicone âitself a polymer âcontaining silicon together with carbon, hydrogen, and oxygen.Silicone rubbers are widely used in industry, and there are multiple formulations.cetoxy tin condensation is one of the oldest cure chemistries used for curing silicone rubber, and is the one used in household bathroom caulk. The smell of vinegar in the form of acetic acid is the usual indicator that the reaction is incomplete.
Silicone, by contrast, is a synthetic polymer made up of silicon, oxygen and other elements, most typically carbon and hydrogen. Silicone is generally a liquid or a flexible, rubberlike plastic, and has a number of useful properties, such as low toxicity and high heat resistance.ilicon is the 14th element on the periodic table. It's a metalloid, meaning it has properties of both metals and nonmetals, and is the second most abundant element in the Earth's crust, after oxygen.
