Text ↔ Binary

Binary code represents text using only 0s and 1s. Each character is converted to its ASCII value, then to an 8-bit binary number. For example, "A" = 65 = 01000001.

Each character is converted to its ASCII code, then to binary. "Hi" becomes: H(72)=01001000, i(105)=01101001, resulting in "01001000 01101001".

Computers use binary because electronic circuits have two states: on (1) and off (0). All data—text, images, programs—is ultimately stored and processed as binary.
