The article explains the historical design choice in ASCII encoding where lowercase letters don't immediately follow uppercase letters, revealing that the 6-character gap was intentionally created so that converting between cases only requires flipping the 5th bit. This clever design optimized for early computing efficiency, though it might seem counterintuitive today. The piece provides insight into the practical considerations that shaped fundamental computing standards.
Background
ASCII (American Standard Code for Information Interchange) is a character encoding standard that was developed in the 1960s and became one of the most influential standards in computing. It uses 7 bits to represent 128 characters, including English letters, digits, and various control characters.
