Understanding Binary Numbers and Systems

The video tutorial introduces the concept of binary, explaining its fundamental role in computing. It contrasts the base 10 number system, which is familiar to most people, with the base 2 binary system used by computers. The tutorial illustrates how binary is used in electrical circuits and demonstrates how numbers are represented in binary. It concludes by highlighting how binary underpins all data storage and processing in computers, despite appearing complex compared to the decimal system.
