📖 How Binary Works
Binary is a base-2 numeral system that uses only two digits: 0 and 1. Computers use binary because electronic circuits have two states: on (1) and off (0).
Text to Binary Conversion
Each character in text has a numeric code (ASCII or Unicode). This number is converted to binary. For example:
- 'A' = ASCII 65 =
01000001 - 'a' = ASCII 97 =
01100001 - '1' = ASCII 49 =
00110001 - ' ' (space) = ASCII 32 =
00100000
💡 Fun Fact: The word "Hello" in binary is:
01001000 01100101 01101100 01101100 01101111
❓ Frequently Asked Questions
Binary is the fundamental language of computers. All data – text, images, videos, and programs – is ultimately stored and processed as binary. Understanding binary helps you understand how computers work at the most basic level.
8-bit (ASCII) uses 8 binary digits for each character, supporting 256 characters. Unicode uses more bits and can represent over 100,000 characters from all writing systems worldwide, including emojis.
