Ternary notation is impressively efficient, using two “trits” to represent nine numbers as opposed to four numbers with binary. Although systems with more states seem like they would be more efficient, ternary turns out to be the most economical way to represent large numbers in an integer base. Base 3 not only offers numerical efficiency, but also computational advantages by reducing the number of queries needed to answer questions with multiple possible answers. Despite its natural advantages, ternary computing never took off due to convention favoring binary computing. However, recent progress has been made in developing cybersecurity systems using base 3 computing to manage erratic information effectively.
