Computer Organization and Architecture Multiple Choice Questions on “Interface Circuits”.
1. ______ serves as an intermediary between the device and the BUSes.
a) Interface circuits
b) Device drivers
c) Buffers
d) None of the mentioned
Answer: a
Clarification: The interface circuits act as a hardware interface between the device and the software side.
2. The side of the interface circuits, that has the data path and the control signals to transfer data between interface and device is _____
a) BUS side
b) Port side
c) Hardwell side
d) Software side
Answer: b
Clarification: This side connects the device to the motherboard.
3. What is the interface circuit?
a) Helps in installing of the software driver for the device
b) Houses the buffer that helps in data transfer
c) Helps in the decoding of the address on the address BUs
d) None of the mentioned
Answer: c
Clarification: Once the address is put on the BUS the interface circuit decodes the address and uses the buffer space to transfer data.
4. The conversion from parallel to serial data transmission and vice versa takes place inside the interface circuits.
a) True
b) False
Answer: a
Clarification: By doing this the interface circuits provide a better interconnection between devices.
5. The parallel mode of communication is not suitable for long devices because of ______
a) Timing skew
b) Memory access delay
c) Latency
d) None of the mentioned
Answer: a
Clarification: None.
6. The Interface circuits generate the appropriate timing signals required by the BUS control scheme.
a) True
b) False
Answer: a
Clarification: The interface circuits generate the required clock signal for the synchronous mode of transfer.
7. The status flags required for data transfer is present in _____
a) Device
b) Device driver
c) Interface circuit
d) None of the mentioned
Answer: c
Clarification: The circuit holds the flags which are required for data transfers.
8. User programmable terminals that combine VDT hardware with built-in microprocessor is _____
a) KIPs
b) Pc
c) Mainframe
d) Intelligent terminals
Answer: d
Clarification: None.
9. Which most popular input device is used today for interactive processing and for the one line entry of data for batch processing?
a) Mouse
b) Magnetic disk
c) Visual display terminal
d) Card punch
Answer: a
Clarification: In batch processing systems the processes are grouped into batches and they’re executed in batches.
10. 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.
a) Registers
b) Memory
c) Buffer
d) CPU
Answer: c
Clarification: When the processor is busy with the process the data to be printed is stored in the buffer.
