Encoding Reference
| Char | Binary | Hex | Octal | Decimal |
|---|---|---|---|---|
| A | 01000001 | 41 | 101 | 65 |
| Z | 01011010 | 5A | 132 | 90 |
| a | 01100001 | 61 | 141 | 97 |
| 0 | 00110000 | 30 | 060 | 48 |
| SP | 00100000 | 20 | 040 | 32 |
Non-ASCII characters (e.g. emojis, accented letters) are encoded as multi-byte UTF-8 sequences.
❓ Frequently Asked Questions
How does text to binary conversion work?+
Each character has an ASCII/Unicode number. That number is converted to its binary (base-2) representation. For example, 'A' = 65 in ASCII = 01000001 in binary.
What is hexadecimal?+
Hexadecimal (base-16) uses digits 0-9 and letters A-F. It's widely used in computing because each hex digit represents exactly 4 binary bits, making it a compact way to write binary data.
Why is binary important in computing?+
Computers fundamentally operate on binary (0s and 1s) because transistors have two states: on and off. All data — text, images, audio — is ultimately stored and processed as binary.
