650 results about "Binary encoding" patented technology

Binary encoding is a type of code used primarily to program computers at the most basic level. It consists of a system of ones and zeros, designed to represent either a "true" or a "false" value in logical operations. Binary encoding was developed by Claude Shannan in the 1930s using switches.
