The term 'number comprised of binary digits' is a reference to a decimal number, which is a base-10 number system. A binary number is a base-2 number system, meaning that it only consists of two digits, 0 and 1. A decimal number can be converted into a binary number by breaking it down into its component parts and then representing each part with a 0 or 1. For example, the decimal number 10 would be represented as 1010 in binary.
