Which of the following best describes the main function of binary code in computers?

The main function of binary code in computers is to represent data in a form that computer processors can manipulate. Binary code is composed of two states, typically represented as 0 and 1. These two states align with the electrical signals used in computer hardware, where off can represent 0 and on can represent 1.

When data is encoded into binary, it allows the computer's processor to interpret instructions, perform calculations, and manage data storage and retrieval effectively. Every piece of information that a computer processes—whether it is text, images, sound, or video—is ultimately converted into binary code, enabling the CPU to handle it efficiently.

While storing images and graphics, facilitating communication between devices, and programming software applications are important aspects of computing, they rely on binary code as the underlying representation of all types of data. Thus, the primary role of binary code is in its capacity to serve as the fundamental language that allows computers to process and manipulate information.
