  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Infinity  \In*fin"i*ty\,  n.;  pl  {Infinities}.  [L.  infinitas 
  pref.  in-  not  +  finis  boundary,  limit,  end:  cf  F. 
  infinit['e].  See  {Finite}.] 
  1.  Unlimited  extent  of  time,  space,  or  quantity;  eternity; 
  boundlessness;  immensity.  --Sir  T.  More 
 
  There  can  not  be  more  infinities  than  one  for  one 
  of  them  would  limit  the  other  --Sir  W. 
  Raleigh. 
 
  From  WordNet  r  1.6  [wn]: 
 
  infinity 
  n  :  time  without  end  [syn:  {eternity},  {forever}] 
 
  From  Jargon  File  (4.2.3,  23  NOV  2000)  [jargon]: 
 
  infinity  n.  1.  The  largest  value  that  can  be  represented  in  a 
  particular  type  of  variable  (register,  memory  location,  data  type 
  whatever).  2.  `minus  infinity':  The  smallest  such  value,  not 
  necessarily  or  even  usually  the  simple  negation  of  plus  infinity. 
  In  N-bit  twos-complement  arithmetic,  infinity  is  2^(N-1)  -  1  but  minus 
  infinity  is  -  (2^(N-1)),  not  -(2^(N-1)  -  1).  Note  also  that  this  is 
  different  from  "time  T  equals  minus  infinity",  which  is  closer  to  a 
  mathematician's  usage  of  infinity. 
 
 
 
  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  infinity 
 
  1.    The  size  of  something  {infinite}. 
 
  Using  the  word  in  the  context  of  sets  is  sloppy,  since 
  different  {infinite  set}s  aren't  necessarily  the  same  size 
  {cardinality}  as  each  other 
 
  See  also  {aleph  0} 
 
  2.    The  largest  value  that  can  be  represented  in 
  a  particular  type  of  variable  ({register},  memory  location, 
  data  type  whatever). 
 
  See  also  {minus  infinity}.
