Computer Organization and Architecture MCQ on BUS Structure

This set of Computer Organization and Architecture MCQ focuses on “Bus Structure”.

  1. The main virtue for using single Bus structure is ,
  2. a) Fast data transfers
  3. b) Cost effective connectivity and speed
  4. c) Cost effective connectivity and ease of attaching peripheral devices
  5. d) None of these

View Answer

Answer:c

Explanation: By using single BUS structure we can minimize the amount hardware (wire) required and thereby reducing the cost.

  1. ______ are used to over come the difference in data transfer speeds of various devices .
  2. a) Speed enhancing circuitory
  3. b) Bridge circuits
  4. c) Multiple Buses
  5. d) Buffer registers

View Answer

Answer:d

Explanation: 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.

  1. To extend the connectivity of the processor bus we use ______ .
  2. a) PCI bus
  3. b) SCSI bus
  4. c) Controllers
  5. d) Multiple bus

View Answer

Answer:a

Explanation: PCI BUS is used to connect other peripheral devices which require a direct connection with the processor.
