Definition - What does Binary Code mean?
Techopedia explains Binary Code
Machine code uses sets of binary digits to form instructions. Along with being the most basic form of code, binary also represents the smallest amount of data that flows through all of the various complex hardware and software systems handling today’s data resources and assets. The smallest amount of data is called a bit, and is represented by either a one or a zero. Ongoing strings of these bits become the code or data that's interpreted by a computer.
The nature of binary code and binary data is an interesting part of the fundamental world of IT. It is most familiar to those who work behind the scenes to create today's user-oriented technologies, which often keep all kinds of computer code hidden from users.
