What is Binary Conversion?

Every character you type — letters, numbers, spaces, symbols — has a numeric code (its ASCII or Unicode value). Binary conversion expresses that number in base-2 (only 0s and 1s), the native language of computers. For example, the letter A has ASCII value 65, which in 8-bit binary is 01000001.
