How to Convert Decimal Numbers to Binary
What is Binary Number System?
Binary number system is a positional numeral system with base 2, using only two digits: 0 and 1. It's the foundation of all digital devices, including computers, smartphones, and other electronics.
Algorithm for Converting Decimal to Binary
To convert a decimal number to binary, use the division by 2 method:
- Divide the decimal number by 2
- Record the remainder (0 or 1)
- Continue dividing the quotient by 2 until you get 0
- Write all remainders in reverse order
Example: Converting Number 10
Decimal number: 10
- 10 ÷ 2 = 5 (remainder 0)
- 5 ÷ 2 = 2 (remainder 1)
- 2 ÷ 2 = 1 (remainder 0)
- 1 ÷ 2 = 0 (remainder 1)
Binary number: 1010 (read remainders from bottom to top)
Applications of Binary System
- Programming — working with bitwise operations
- Computer Networks — IP addresses and subnet masks
- Digital Electronics — logic circuits
- Cryptography — data encryption
- Data Compression — storage optimization
