Frequently Asked Questions
How is text stored as binary?▾
Each character is mapped to a number via ASCII (or Unicode). That number is then expressed in binary. E.g. "A" = ASCII 65 = binary 01000001.
What is ASCII?▾
American Standard Code for Information Interchange — a character encoding that maps 128 characters (A–Z, a–z, 0–9, punctuation) to numbers 0–127.
Why 8 bits?▾
8 bits = 1 byte, the standard unit of computer memory. 8 bits can represent 256 values (0–255), enough to cover all ASCII characters plus extended characters.
