What is ASCII?
ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns a unique number to each character. Originally defined for 128 characters (0–127), it covers English letters, digits, punctuation and control characters. For example, A = 65, a = 97, 0 = 48.
ASCII codes are used in programming, networking, data transmission and text processing. Knowing ASCII values helps in understanding character encoding, sorting algorithms and low-level data manipulation.
