Computer Bus Systems Quiz

In which type of Bus arbitration is the division of Bus usage rights handled by a single Bus arbitration unit?

• Decentralized Bus Arbitration or Centralized Bus Arbitration

• Referee Bus focuses

• There is no Bus referee

• Referee Bus is not focused

What is the function of the System Bus in a computer?

• Connects the microprocessor to the main memory, L3 cache memory and I/O coupling controllers

• Is the transmission line between blocks of the microprocessor

• Transmission line between CPU and intermediate support chips

• Connect the input and output system to the microprocessor

With the hardware polling method (in determining the interrupt module), which of the following statements is false?

• The system has an interrupt accept line (INTA) connecting from the CPU to the I/O modules in series.

• The order of connecting I/O modules in series determines the priority order of I/O modules

• The system has an interrupt request line (INTR) connected from the I/O modules to the CPU

• The system has many interrupt request lines with specified priority levels

Which of the following characteristics is not of a synchronous bus?

• Bus period remains unchanged for all pairs of devices exchanging data

• All operations are performed in time intervals that are multiples of the Bus period

• Data exchange between devices requires a handshake signal

• The system is timed intermittently

What is the function of the Bus system in a computer?

• Changing the signal format in the computer

• Link components in the computer

• Expand your computer's communication functions

• Control peripheral devices

What is the function of the microprocessor bus in a computer?

• Is the transmission line between blocks of the microprocessor

• Transmission path between CPU and L2 Cache

• Connect the input and output system to the microprocessor

• Connects the processor to main memory

For serial input and output connections, which of the following statements is false?

• Transmit bits one at a time

• A converter from parallel to serial data or/and vice versa is required

• Requires few data lines

• Transmit multiple bits at once

How many data lines does the IBM Pc bus have?

• 16 lines

• 6 lines

• 8 lines

• 10 lines

Methods for determining interrupt modules include

• Using multiple interrupt request lines, software polling, hardware polling, using interrupt controller

• Using multiple interrupt request lines, software polling, hardware polling, taking up CPU

• Using multiple interrupt request lines, software polling, hardware polling, taking up memory

• Polling by software, polling by hardware, takes up CPU, takes up memory

Characteristics of centralized Bus arbitration:

• The Bus arbitration unit is located at the center of the computer

• The division of Bus usage rights is undertaken by a single Bus arbitration unit

• The Bus arbitration unit also owns the Bus

• The division of Bus usage rights is done by the peripheral devices themselves
