Binary Numbers Unveiled: Understanding the Transition from Binary to Decimal

The video tutorial explains the binary number system and its similarities to the decimal system. It covers how each place in a binary number represents a power of two, unlike the decimal system where each place represents a power of ten. The tutorial demonstrates converting binary numbers to decimal by multiplying each bit by its corresponding power of two and summing the results. It also explores larger binary numbers and their decimal equivalents, highlighting the efficiency of binary for computer hardware despite its larger bit requirement compared to decimal.

What is the main difference between the binary and decimal number systems?

• Binary uses powers of 5, decimal uses powers of 10

• Binary uses powers of 2, decimal uses powers of 10

• Binary uses powers of 10, decimal uses powers of 2
