Binary encoding is a method of representing data using only two symbols, typically 0 and 1. This system is fundamental to computer science, as it allows computers to process and store information efficiently. Each digit in a binary number is called a bit, and combinations of bits can represent various types of data, such as numbers, letters, and images. In binary encoding, each character or value is assigned a unique binary code. For example, the letter A is represented as 01000001 in ASCII encoding. This simplicity enables computers to perform complex operations and communicate effectively, as all data can ultimately be reduced to binary form.
