![Silicon (pronounced /ˈsɪlɨkən/ SIL-ə-kən or /ˈsɪlɨkɒn/ SIL-ə-kon, Latin: silicium) is the most common metalloid. It is a chemical element, which has the symbol Si and atomic number 14. A tetravalent metalloid, silicon is less reactive than its chemical analog carbon. As the eighth most common element in the universe by mass, silicon very rarely occurs as the pure free element in nature, but is more widely distributed in dusts, planetoids and planets as various forms of silicon dioxide (silica) orsilicates. In Earth’s crust, silicon is the second most abundant element after oxygen, making up 25.7% of the crust by mass.[4]
BlackBerry is a line of wireless mobile device that was introduced in 1999 as a two-way pager. In 2002, the more commonly knownsmartphone BlackBerry was released, which supports push e-mail, mobile telephone, text messaging, internet faxing, web browsing and other wireless information services. It is an example of a convergent device. Developed by the Canadian company Research In Motion(RIM), it delivers information over the wireless data networks of mobile phone service companies. BlackBerry first made headway in themarketplace by concentrating on e-mail. RIM currently offers BlackBerry e-mail service to non-BlackBerry devices, such as the Palm Treo, through the BlackBerry Connect software. The original BlackBerry device had a monochrome display, but all current models have color displays, and are market leaders in innovation, specifically surrounding multi-tasking operating systems and integration with backend messaging and collaboration and customised application systems.[citation needed]](http://30.media.tumblr.com/tumblr_kusxh7G8IP1qzm0n1o1_500.jpg)
