The binary number system forms the basis of the entire digital world. Understanding the principles of converting to the binary number system opens the way to mastering computer technologies and programming.
History of the Creation of the Binary System
Gottfried Wilhelm Leibniz developed the modern binary system in the 17th century. However, research shows that early forms of binary counting existed in ancient civilizations of Egypt and China.
Key Principles of the Binary System
The binary system uses a base of 2 and includes only two digits: 0 and 1. Each position in a binary number represents a power of two.
The number 1011₂ is decoded as: 1×2³ + 0×2² + 1×2¹ + 1×2⁰ = 8 + 0 + 2 + 1 = 11₁₀
Conversion from Decimal to Binary System
Algorithm of Sequential Division:
- Divide the original number by 2
- Write down the remainder (0 or 1)
- Repeat with the integer part until you get 0
- Write down the remainders in reverse order
Conversion of 11 to Binary Number System
- 11 ÷ 2 = 5 (remainder 1)
- 5 ÷ 2 = 2 (remainder 1)
- 2 ÷ 2 = 1 (remainder 0)
- 1 ÷ 2 = 0 (remainder 1)
- Result: 1011₂
Conversion of 53 to Binary Number System
- 53 ÷ 2 = 26 (remainder 1)
- 26 ÷ 2 = 13 (remainder 0)
- 13 ÷ 2 = 6 (remainder 1)
- 6 ÷ 2 = 3 (remainder 0)
- 3 ÷ 2 = 1 (remainder 1)
- 1 ÷ 2 = 0 (remainder 1)
- Result: 110101₂
Working with Octal Numbers
Converting 53 8 to the binary number system (if 53 is octal):
- 5₈ = 101₂
- 3₈ = 011₂
- Result: 101011₂
Converting 127 8 to the binary number system (octal 127):
- 1₈ = 001₂
- 2₈ = 010₂
- 7₈ = 111₂
- Result: 001010111₂ = 1010111₂
Practical Examples of Conversion
Conversion of 2 to Binary Number System:
- 2 ÷ 2 = 1 (remainder 0)
- 1 ÷ 2 = 0 (remainder 1)
- Result: 10₂
Conversion of 12 to Binary Number System:
- 12 ÷ 2 = 6 (remainder 0)
- 6 ÷ 2 = 3 (remainder 0)
- 3 ÷ 2 = 1 (remainder 1)
- 1 ÷ 2 = 0 (remainder 1)
- Result: 1100₂
Conversion to Binary Number System 538 (decimal):
- 538 ÷ 2 = 269 (remainder 0)
- 269 ÷ 2 = 134 (remainder 1)
- 134 ÷ 2 = 67 (remainder 0)
- 67 ÷ 2 = 33 (remainder 1)
- 33 ÷ 2 = 16 (remainder 1)
- 16 ÷ 2 = 8 (remainder 0)
- 8 ÷ 2 = 4 (remainder 0)
- 4 ÷ 2 = 2 (remainder 0)
- 2 ÷ 2 = 1 (remainder 0)
- 1 ÷ 2 = 0 (remainder 1)
- Result: 1000011010₂
