pahc 6.3

Which parameter of the Bus indicates its line?

• Bus width

• All 3 bandwidth, width, frequency of the Bus

• Bus bandwidth

• Bus frequency

It is not possible to connect a peripheral device directly to the system bus because (please point out the incorrect statement ):

• Data in the computer is in the form of binary numbers, while data in peripheral devices is in the form of physical signals (light, sound, ...)

• There exist a variety of peripheral devices that differ in operating principles, data formats, and operating speeds, so the processor cannot control all of these devices.

• Manufacturers cannot manufacture devices that connect directly between the processor and peripherals

• All peripherals operate slower than the processor and RAM

What are the important characteristics of the synchronous bus?

• Data is transmitted simultaneously

• Data is not transmitted simultaneously

• There is a common clock signal that controls the operation

• There is no common clock signal controlling the operation

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

• Transmit multiple bits at once

• Fast speed

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

• Needs multiple data lines

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

• Transmit multiple bits at once

• Transmit bits one by one sequentially

• Fast speed

• Needs multiple data lines

With the program input and output method, which of the following statements is correct?

• Is a method completely processed by hardware

• This is the data exchange method with the fastest and most complex circuit design

• Is a method completely processed by software

• Is a processing method using both hardware and software

Characteristics of decentralized bus arbitration with multibus:

• The division of Bus usage rights does not require a separate Bus arbitration unit

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

• The Bus arbitration unit is not centrally located on the computer

• The Bus arbitration unit also owns the Bus

With the interrupt input and output method, which of the following statements is correct?

• Is a method completely processed by hardware

• Peripheral devices are active objects in data exchange

• Is a method completely processed by software

• CPU is the active object in data exchange

For parallel input and output connections, which of the following statements is correct?

• Transmit multiple bits at once

• Transmit bits one at a time

• Requires few data lines

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

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

• Transmit multiple bits at once

• Fast speed

• Requires few data lines

• Needs multiple data lines
