  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Silicon  \Sil"i*con\,  n.  [See  {Silica}.]  (Chem.) 
  A  nonmetalic  element  analogous  to  carbon.  It  always  occurs 
  combined  in  nature,  and  is  artificially  obtained  in  the  free 
  state,  usually  as  a  dark  brown  amorphous  powder,  or  as  a  dark 
  crystalline  substance  with  a  meetallic  luster.  Its  oxide  is 
  silica,  or  common  quartz,  and  in  this  form  or  as  silicates, 
  it  is  next  to  oxygen,  the  most  abundant  element  of  the 
  earth's  crust.  Silicon  is  characteristically  the  element  of 
  the  mineral  kingdom,  as  carbon  is  of  the  organic  world. 
  Symbol  Si  Atomic  weight  28.  Called  also  {silicium}. 
 
  From  WordNet  r  1.6  [wn]: 
 
  silicon 
  n  :  a  tetravalent  nonmetallic  element;  next  to  oxygen  it  is  the 
  most  abundant  element  in  the  earth's  crust;  occurs  in 
  clay  and  feldspar  and  granite  and  quartz  and  sand;  used 
  as  a  semiconductor  in  transistors  [syn:  {Si},  {atomic 
  number  14}] 
 
  From  Jargon  File  (4.2.3,  23  NOV  2000)  [jargon]: 
 
  silicon  n.  Hardware,  esp.  ICs  or  microprocessor-based  computer 
  systems  (compare  {iron}).  Contrasted  with  software.  See  also 
  {sandbender}. 
 
 
 
  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  silicon 
 
  1.    The  material  used  as  the  base  (or 
  "substrate")  for  most  {integrated  circuit}s. 
 
  2.    {Hardware},  especially  {integrated  circuit}s  or 
  {microprocessor}-based  computer  systems  (compare  {iron}). 
 
  Contrast:  {software}.  See  also  {sandbender}.

  From  Elements  database  20001107  [elements]: 
 
  silicon 
  Symbol:  Si 
  Atomic  number:  14 
  Atomic  weight:  28.086 
  Metalloid  element  belonging  to  group  14  of  the  periodic  table.  It  is  the 
  second  most  abundant  element  in  the  Earth's  crust,  making  up  25.7%  of  it 
  by  weight.  Chemically  less  reactive  than  carbon.  First  identified  by 
  Lavoisier  in  1787  and  first  isolated  in  1823  by  Berzelius.
