Fun Fact
The decimal value for the uppercase letter A in ASCII is 65, and for lowercase a it is 97. This predictable pattern makes ASCII extremely useful for programming and digital communication.
Historical Context
ASCII stands for American Standard Code for Information Interchange. It was developed in the early 1960s to create a universal standard for representing text in computers and communication devices. Before ASCII, many incompatible encoding systems existed. The ASCII standard unified them into a simple 7-bit system capable of representing letters, numbers, punctuation, and control characters. Even today, modern character encodings like UTF-8 remain backward compatible with ASCII, making it one of the most influential standards in computing history.
