The Complete Beginners Guide to Arduino - 2021 - Bits and Bytes

The video tutorial explains the decimal and binary number systems, highlighting their differences and similarities. It describes how numbers are represented in both systems, using symbols and columns to determine value. The tutorial covers the conversion process between binary and decimal numbers, providing step-by-step examples. It also introduces the concepts of bits and bytes, explaining their significance in data representation.

What is the primary reason humans use the decimal system?

• It is easier to calculate with.

• It is the most efficient system.

• It is based on the number of fingers humans have.

• It was the first system invented.

In the binary system, what does the number '10' represent in decimal?

• 10

• 1

• 2

• 3

How is the value of a binary number determined?

• By adding the digits together.

• By multiplying each digit by 10.

• By using each digit as an exponent of two.

• By converting it directly to decimal.

What is the first step in converting a decimal number to binary?

• Subtract one from the number.
