Understanding Binary and Bits

This tutorial introduces binary, explaining its significance in computing. It covers the basics of bits and bytes, contrasting digital and analog systems. The video demonstrates how to represent numbers using binary, using light bulbs as a visual aid. It also teaches counting in binary from 0 to 15, highlighting the relationship between bits and the number of values they can represent. The tutorial concludes with a summary and directs viewers to additional resources for further learning.
