_____ serves as a intermediary between the device and the BUSes.
Explanation: The interface circuits act as an hardware interface between the device and the software side.
The side of the interface circuits, that has the data path and the control signals to transfer data between interface and device is _____
Explanation: This side connects the device to the motherboard.
The interface circuits
Explanation: Once the address is put on the BUS the interface circuit decodes the address and uses the buffer space to transfer data
The conversion from parallel to serial data transmission and vice versa takes place inside the interface circuits.
Explanation: By doing this the interface circuits provides a better interconnection between devices.
The parallel mode of communication is not suitable for long devices because of ______
The Interface circuits generates the appropriate timing signals required by the BUS control scheme.
Explanation: The interface circuits generates the required clock signal for the synchronous mode of transfer.
The status flags required for data transfer is present in _____
Explanation: The circuit holds the flags which are required for data transfers.
User programmable terminals that combine VDT hardware with built-in microprocessor is _____
Which most popular input device is used today for interactive processing and for the one line entry of data for batch processing?
Explanation: In batch processing systems the processes are grouped into batches and they’re executed in batches.
The use of spooler programs or _______ Hardware allows PC operators to do the processing work at the same time a printing operation is in progress.
Explanation: When the processor is busy with the process the data to be printed is stored in the buffer.
