🔢
Binary (Base 2)
Used in all digital electronics and programming. Each digit is a single bit — 0 or 1.
🔟
Hexadecimal (Base 16)
Compact binary representation. 2 hex digits = 1 byte. Used in colors, addresses, hashes.
8️⃣
Octal (Base 8)
Historically used in Unix file permissions (chmod 755). Each digit represents 3 bits.

Understanding Common Number Bases

🔢 Binary (Base 2)

Uses only 0 and 1. Binary is the foundation of all digital computing and electronic systems — every piece of data processed by a CPU is ultimately binary.

8️⃣ Octal (Base 8)

Uses digits 0–7. Historically used in Unix systems for compact binary grouping. Each octal digit represents exactly 3 bits. Example: chmod 755

🔟 Decimal (Base 10)

The standard human number system using digits 0–9. This is the everyday counting system used across science, finance, and engineering.

🔠 Hexadecimal (Base 16)

Uses 0–9 and A–F. Widely used in memory addresses, color codes, cryptographic hashes, and machine-level programming. 2 hex digits = 1 byte. Example: #FF5733

🔡 Base 36

Uses 0–9 and A–Z. Often used for short IDs, URL slugs, compact identifiers, and encoding systems where a human-readable, case-insensitive, compact format is needed.
