Assume a ternary computer in which the basic unit of memory is a trit (ternary digit) rather than a bit. A trit can have three possible settings (0, 1 and 2) rather than just two (0 and 1). Show how nonnegative integer can be represented in ternary notation using trits by a method analogous to binary notation using bits. Is there any nonnegative integer that can be represented using ternary notation and trits that cannot be represented using binary notation and bits? Are there any that can be represented using bits that can not be represented using trits? Why are binary computers more common than ternary computers?
