The function of a logic circuit in computing is to perform logic operations on binary data. Logic circuits, often implemented using gates like AND, OR, and NOT, operate on binary inputs (0s and 1s) to produce binary outputs based on specific logical rules. These circuits are fundamental to the design of computational devices, allowing them to perform tasks such as calculations, decision-making processes, and the execution of algorithms.

In the context of computing, logic operations enable the processing of data by evaluating conditions and making computations that drive the broader functionality of systems. This is particularly essential for operations like addition, subtraction, and other arithmetic functions that are the backbone of programming and data manipulation.

The other options pertain to different functions: storing data relates to memory components like RAM or hard drives, transmitting data refers to communication channels and protocols, while encrypting data involves securing information so that it is only accessible to authorized parties. Each of these functions serves distinct roles within a computer system but does not characterize the primary role of logic circuits, which is centered around logical processing.
