Fun Fact
Hexadecimal uses sixteen symbols: 0-9 and A-F. One hexadecimal digit represents exactly four binary digits, making it extremely efficient for representing binary data in a compact and human-readable form. For example, the decimal number 255 becomes FF in hexadecimal.
Historical Context
The hexadecimal numbering system became widely adopted in the early days of computing because of its direct relationship with binary. Engineers needed a concise way to represent machine-level data. Since one hex digit maps perfectly to four bits, it became a standard notation in assembly language, memory addressing, and debugging tools. Today, hexadecimal remains fundamental in modern computing, from RGB color values in CSS to cryptographic hashes and low-level system diagnostics.
