Computer Organization and Architecture Multiple Choice Questions on “BUS Structure”.
1. The main virtue for using single Bus structure is ____________
a) Fast data transfers
b) Cost effective connectivity and speed
c) Cost effective connectivity and ease of attaching peripheral devices
d) None of the mentioned
Answer: c
Clarification: By using a single BUS structure we can minimize the amount of hardware (wire) required and thereby reducing the cost.
2. ______ are used to overcome the difference in data transfer speeds of various devices.
a) Speed enhancing circuitory
b) Bridge circuits
c) Multiple Buses
d) Buffer registers
Answer: d
Clarification: By using Buffer registers, the processor sends the data to the I/O device at the processor speed and the data gets stored in the buffer. After that the data gets sent to or from the buffer to the devices at the device speed.
3. To extend the connectivity of the processor bus we use ________
a) PCI bus
b) SCSI bus
c) Controllers
d) Multiple bus
Answer: a
Clarification: PCI BUS is used to connect other peripheral devices that require a direct connection with the processor.
4. IBM developed a bus standard for their line of computers ‘PC AT’ called _____
a) IB bus
b) M-bus
c) ISA
d) None of the mentioned
Answer: c
Clarification: None.
5. The bus used to connect the monitor to the CPU is ______
a) PCI bus
b) SCSI bus
c) Memory bus
d) Rambus
Answer: b
Clarification: SCSI BUS is usually used to connect video devices to the processor.
6. ANSI stands for __________
a) American National Standards Institute
b) American National Standard Interface
c) American Network Standard Interfacing
d) American Network Security Interrupt
Answer: a
Clarification: None.
7. _____ register Connected to the Processor bus is a single-way transfer capable.
a) PC
b) IR
c) Temp
d) Z
Answer: d
Clarification: The Z register is a special register which can interact with the processor BUS only.
8. In multiple Bus organisation, the registers are collectively placed and referred as ______
a) Set registers
b) Register file
c) Register Block
d) Map registers
Answer: b
Clarification: None.
9. The main advantage of multiple bus organisation over a single bus is _____
a) Reduction in the number of cycles for execution
b) Increase in size of the registers
c) Better Connectivity
d) None of the mentioned
Answer: a
Clarification: None.
10. The ISA standard Buses are used to connect ___________
a) RAM and processor
b) GPU and processor
c) Harddisk and Processor
d) CD/DVD drives and Processor
Answer: c
