How Text is Stored as Binary

Computers store all data — text, images, audio — as sequences of bits (binary digits: 0 or 1). Text characters are mapped to numbers using encoding standards like ASCII (7-bit, 128 characters) or UTF-8 (variable-length, supports all Unicode characters).

In ASCII, each character is represented by 7 bits (padded to 8 bits / 1 byte). For example, the letter "A" is decimal 65, which is 01000001 in binary.

QR codes and barcodes ultimately encode data as binary patterns — black modules represent 1s and white modules represent 0s. Understanding binary helps you grasp how data is stored at the most fundamental level.
