What is the language of computers?

The language of computers encompasses various representations that enable digital systems to process and understand data. The correct choice here, ones and zeros, is foundational to how computers operate. Computers function using a binary system, which consists of two states represented by 0 and 1. This binary format is not just a language; it's the very core of digital communication and processing, as all higher-level data and instructions are ultimately converted into binary for the computer to execute.

Ones and zeros represent the simplest form of data that a computer can understand, allowing it to perform complex calculations and tasks through combinations of these two symbols. While binary code and machine language refer to specific formal languages that utilize this binary representation, the essence of computer language is fundamentally about the digits 0 and 1.

ASCII text, while an important encoding system for characters, operates above the binary layer. It utilizes binary to represent alphanumeric characters but does not define the language of computers at the most fundamental level. Thus, while the other options are related, they build upon the foundational concept represented by ones and zeros, emphasizing this choice as the most accurate description of the language of computers.
