Encoder / Decoder / Comparator

The Syntax of Digital Identity

The Machinery of Meaning

Raw binary data must be compressed for transmission, expanded for action, and evaluated for logic. Encoders translate physical events into compact binary codes. Decoders take those codes and fan them out to trigger specific hardware responses. Comparators bridge the gap between numbers, allowing the machine to judge equality and magnitude. Together, they form the interactive interface of all digital subsystems.

DIGITAL INFORMATION → ENCODE (COMPRESS) → COMPARE (EVALUATE) → DECODE (EXPAND) → SYSTEM CONTROL
