____ serves as an intermediary between the device and the BUSes.
A
Interface circuits
B
Device drivers
C
Buffers
D
None of the mentioned
Explanation: 

Detailed explanation-1: -1. serves as an intermediary between the device and the BUSes. Explanation: The interface circuits act as a hardware interface between the device and the software side. Explanation: This side connects the device to the motherboard.

Detailed explanation-2: -Explanation: The bridge circuit is basically used to extend the processor BUS to connect devices.

Detailed explanation-3: -Integrated circuits are available which are specifically designed to provide the interface between computer and similar interactive terminals. Such a circuit is called an asynchronous communication interface or a universal asynchronous receivertransmitter (UART).

Detailed explanation-4: -The interface circuit has a data register that stores the data temporarily while the data is being exhanged between I/O and processor. The interface circuit also has a status register, the bits in the status register indicate the processor whether the I/O device is set for the transmission or not.

Detailed explanation-5: -An interface circuit is a signal conditioning circuit used to bring signal from the sensor up to the format that is compatible with the load device.
