What device is used to configure communication between a computer and its peripherals?

The correct choice identifies a device driver as the key component that facilitates communication between a computer and its peripherals. Device drivers are specialized software programs that allow the operating system to interact with hardware components such as printers, scanners, keyboards, and mice. When a peripheral is connected to a computer, the operating system uses its corresponding driver to understand how to communicate with that device, send data, and receive data appropriately. Without the correct drivers installed, the operating system may not recognize or be able to use the peripherals effectively.

In contrast, while network adapters allow for network communication, they do not directly configure communication with peripherals. Modems serve the specific function of connecting computers to the internet over various types of communication lines but do not handle peripheral device communication. Finally, a power supply provides necessary electrical power to the computer and its components but is not involved in the communication processes between the computer and its peripherals.
