In computing, what is the binary system used for?

The binary system is foundational in computing, as it utilizes only two digits, 0 and 1, to represent all forms of data and instructions that a computer processes. Each binary digit, or "bit," is a basic unit of information in computing, and combinations of these bits represent more complex data, including numbers, letters, and commands. This system is essential for programming and allows computers to perform operations through logical and arithmetic processes.

In the context of computing, all functions—ranging from computation to data storage—are ultimately translated into binary to ensure that the hardware can understand and act on the data using its electronic components. This abstraction is what enables computers to operate at incredibly high speeds and with great efficiency.

The other options do touch on aspects of computing but do not accurately encapsulate the primary role of the binary system itself. Translating text into audio or converting sound waves to electronic waves involve processes that may utilize binary data but are more specific applications. Similarly, displaying graphics on a monitor is a function that relies on pixels and color depths, which are also represented in binary but do not directly define the binary system's usage in computing.
