Two stars orbiting one another are in a Binary System
"Occulting binary". The word "occult" means hidden or in shadows; if a binary star's orbital plane happens to be exactly through the Earth's path, we might see two stars when they're separate and then see one of the stars disappear behind (or in front of) the other.

=THE BINARY SYSTEM IS USED IN THE ELECTRICAL COMPUTERS.=
No, our Sun is not part of a binary system.
Another name for the Binary Number System is the base-2 numeral system. In this system, numbers are represented using only two symbols, typically 0 and 1. Each digit in a binary number represents a power of 2, with the rightmost digit representing 2^0 (1), the next digit representing 2^1 (2), and so on.
310=21 + 20 . That is 112 in binary system.
Sixteen in the Binary code system is (1000)2
A.N.D. Leibniz defined the binary number system.
