cons

cons
 /konz/, /kons/

   [from LISP]

   1. vt. To add a new element to a specified list, esp. at the top. "OK,
   cons picking a replacement for the console TTY onto the agenda."

   2. cons up: vt. To synthesize from smaller pieces: "to cons up an
   example".

   In LISP itself, cons is the most fundamental operation for building
   structures. It takes any two objects and returns a dot-pair or
   two-branched tree with one object hanging from each branch. Because
   the result of a cons is an object, it can be used to build binary
   trees of any shape and complexity. Hackers think of it as a sort of
   universal constructor, and that is where the jargon meanings spring
   from.
    

connection-oriented network service
CONS

   <networking> (CONS) Because of the relatively long transit
   delays and inferior bit error rate of {WANs}, a more
   sophisticated {connection-oriented} {protocol} is normally
   used.

cons

   /konz/ or /kons/ [LISP, "construct"] A {Lisp} function which
   takes an element H and a list T and returns a new list whose
   head is H and whose tail is T.

   In {Lisp}, "cons" is the most fundamental operation for
   building structures.  It actually takes any two objects and
   returns a "{dotted-pair}" or two-branched tree with one object
   hanging from each branch.  Because the result of a cons is an
   object, it can be used to build {binary trees} of any shape
   and complexity.
