Fun Fact

The phrase "Hello World" in hexadecimal is 48656c6c6f20576f726c64. Hexadecimal became popular in computing because it maps perfectly to binary: one hex digit represents exactly four bits.

Historical Context

Hexadecimal notation gained prominence in early computing systems during the mid-20th century. Engineers working with low-level memory and machine code needed a compact, human-readable representation of binary data. Because base-16 aligns cleanly with 8-bit bytes, it became the standard format for memory dumps, assembly programming, and debugging tools. Today, hex encoding remains fundamental in networking protocols, cryptography, blockchain systems, and modern software development workflows.
