How Binary Works
What is binary?
Binary is a base-2 number system using only 0 and 1. Computers store and process all data in binary. Each character of text is represented by 8 binary digits (bits), known as a byte.
What is ASCII?
ASCII (American Standard Code for Information Interchange) assigns a number to each character. For example, 'A' = 65, 'a' = 97, '0' = 48. This converter uses ASCII values to translate between text and number systems.
