About Binary Encoding
Binary is the fundamental language of computers, representing all data using only two digits: 0 and 1. Each character in text is converted to its binary representation using 8 bits (one byte). For example, the letter "A" is represented as 01000001 in binary (ASCII value 65).

How Binary Encoding Works
Computers store all data as sequences of 0s and 1s. Each character is assigned a numeric code (like ASCII or Unicode), and that number is then expressed in base-2 (binary). For standard ASCII text, each character uses 8 bits. For example:
