Understanding ASCII & Hexadecimal
ASCII (American Standard Code for Information Interchange) assigns numeric values to characters. Each character is represented by a number from 0-127, which can be displayed in hexadecimal (base-16) format using digits 0-9 and letters A-F. Hexadecimal is commonly used in programming, debugging, and data analysis because it's more compact than binary and easier to read than decimal.
