What is the purpose of interface boards?

The purpose of interface boards is to facilitate communication between different components of a computer system or between various electronic devices. They serve as connectors or intermediaries that enable data transfer and signal processing, ensuring that different hardware components, such as sensors, processors, and output devices, can work together effectively. By maintaining compatibility and managing the flow of data, interface boards play a crucial role in the functioning of communication systems, be it within a computer, between networked devices, or in embedded systems.

Other options focus on distinct hardware functions, like enhancing storage capacity, cooling CPUs, or increasing calculation speed, which are not the primary roles of interface boards. Each of these aspects pertains to different types of components in a computer system rather than the specific task of facilitating communication between them.
