Questions & Answers

Q: What is the difference between the decimal system and the binary system?

The decimal system is based on a base of 10, while the binary system is based on a base of 2. In the decimal system, we have 10 digits to choose from (0-9), while in the binary system, we have only 2 digits (0 and 1).

Q: How do you count in binary numbers?

In binary numbers, you count starting from 1 and then double the previous number each time. So, it goes like 1, 10, 11, 100, 101, and so on.

Q: How do you convert a decimal number to binary?

To convert a decimal number to binary, start with 1 and double it until you exceed the decimal number. Then, add the necessary values from the doubling process to get the binary representation.

Q: How do you convert a binary number to decimal?

To convert a binary number to decimal, assign a value of 1 to the rightmost digit, double that value for each subsequent digit, and then add up the values for the digits that have a value of 1.

Summary & Key Takeaways

• The video explains the difference between the decimal system and the binary system, where the decimal system uses a base of 10 and the binary system uses a base of 2.

• It demonstrates how to count in binary numbers using only ones and zeros, showing that the numbers double in value each time.

• The video also provides step-by-step instructions on how to convert a decimal number to binary and vice versa, using a doubling method.
