This flag is about knowing that everything in a computer runs with the Binary numbering system and how ASCII characters (see <https://www.ascii-code.com/articles/Beginners-Guide-to-ASCII>) are stored in a computer.

Binary, the language of computers, consists of just two digits: 0 and 1. Each binary digit, or bit, represents a power of two, allowing complex data to be efficiently processed by computers. For instance, the binary number 101 represents 1x2^2 + 0x2^1 + 1x2^0, which equals 5 in decimal form. Everything in a computer, from text to images, is ultimately encoded in this simple yet powerful binary system.
