Biannual
Biannual means twice a year.  It's the same as semi-annual.  The term shows up in a lot of money problems in algebra.
Example:  If interest is compounded biannually, then it's compounded twice a year.

Binary
Our regular number system is "base 10" which means that we use TEN digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.  But, there are other number systems.  The binary number system is "base 2" which means that it uses just two digits: 0 and 1.   Computers speak in binary numbers!
Example:  110101 is binary for 53 in our regular number system (base 10).
