Understanding Different Number Systems
- Uses only digits 0 and 1
- Each position represents a power of 2
- Fundamental language of computers
- Used in digital circuits and logic gates
- Essential for understanding computer architecture
| Decimal | Binary | ASCII Character | Common Use |
|---|---|---|---|
| 65 | 01000001 | 'A' | Uppercase letter |
| 97 | 01100001 | 'a' | Lowercase letter |
| 48 | 00110000 | '0' | Number character |
| 32 | 00100000 | Space | Whitespace character |
- Standard character encoding for electronic communication
- Uses 7 bits to represent 128 different characters
- Includes letters, numbers, punctuation, and control characters
- Foundation for more complex encoding systems
- Still widely used in programming and data processing
32-126: Printable characters
127: DEL character
65-90: Uppercase (A-Z)
97-122: Lowercase (a-z)
- Uses digits 0-9 and letters A-F
- Each hex digit represents 4 binary bits
- Compact representation of binary data
- Common in memory addresses and color codes
- Easier to read than long binary strings
| Decimal | Binary | Hex | Example Use |
|---|---|---|---|
| 0 | 0000 | 0 | Zero value |
| 10 | 1010 | A | Hex digit |
| 15 | 1111 | F | Maximum hex digit |
| 255 | 11111111 | FF | Byte maximum value |
Professional Applications
| Field | Common Use Case | Format Preference | Example |
|---|---|---|---|
| Web Development | Color codes, URL encoding | Hexadecimal | #FF5733 (red color) |
| System Programming | Memory addresses, pointers | Hexadecimal | 0x7FFF (memory address) |
| Digital Logic | Circuit design, gates | Binary | 10110101 (state sequence) |
| Data Communication | Protocol headers, packets | Hex/Binary | Protocol data units |
| Cryptography | Hash values, encryption keys | Hexadecimal | SHA-256 hash output |
| Embedded Systems | Microcontroller programming | Binary/Hex | Register configurations |
Programming Language Examples
Python
text = "Hello"
binary = ' '.join(format(ord(c), '08b') for c in text)
print(binary)
# Binary to ASCII
binary = "01001000 01100101"
text = ''.join(chr(int(b, 2)) for b in binary.split())
print(text)
JavaScript
const text = "Hello";
const hex = text.split('').map(c =>
c.charCodeAt(0).toString(16)
).join(' ');
console.log(hex);
// Hex to ASCII
const hex = "48 65 6C 6C 6F";
const text = hex.split(' ').map(h =>
String.fromCharCode(parseInt(h, 16))
).join('');
console.log(text);
Conversion Tips and Best Practices
Pro Tips
- Always verify conversions with known values
- Use consistent formatting (spaces, case)
- Understand the context of your target system
- Consider character encoding (UTF-8, ASCII)
- Test edge cases (special characters, symbols)
- Document conversion methods in code
Common Pitfalls
- Mixing up big-endian vs little-endian
- Forgetting leading zeros in binary/hex
- Assuming ASCII for non-English characters
- Not handling null or control characters
- Incorrect padding in binary representations
- Case sensitivity in hexadecimal values
