Final answer:
The Binary language consists of just two digits, 0 and 1, and is used in computing and digital electronics as a base-2 numeral system.
Step-by-step explanation:
The language that consists of just two digits 0 and 1 is known as the Binary language. This numeral system is used in computers and digital electronics because it is a base-2 system, which means it only uses two symbols: 0 (zero) and 1 (one). Every digit in a binary number is referred to as a bit. Unlike the Decimal system, which is based on powers of 10, the binary system works on powers of 2, with each binary digit representing an increasing power of 2, starting with 20 on the right. For example, the binary number 1011 represents the decimal number 11, which is calculated as (1 × 23) + (0 × 22) + (1 × 21) + (1 × 20).
