A ternary computer (also called trinary computer) is a computer that uses ternary logic (three possible values) instead of the more popular binary system ("Base 2") in its calculations.
== Types of states ==
Ternary computing deals with three discrete states, but the ternary digits themselves can be defined in different ways:
Unbalanced Trinary – {0,1,2}
Fractional Unbalanced Trinary – {0,1/2,1}
Balanced Trinary – {−1,0,1}
Unknown-State Logic – {F,?,T}
Trinary Coded Binary – {T,F,T}
== History ==
One early calculating machine, built entirely from wood by Thomas Fowler in 1840, operated ...
