Device Management Quiz

Which of the following is not a function of device management?

• Tracking device status

• Allocating and deallocating devices

• Managing CPU scheduling

• Managing file access

Devices that can be assigned to only one job at a time are called:

• Shared devices

• Virtual devices

• Dedicated devices

• Peripheral devices

The main disadvantage of dedicated devices is:

• They are too fast for the CPU

• They are inefficient when underused

• They cannot be shared at all

• They consume more power

A printer converted into a sharable device using spooling is an example of a:

• Shared device

• Virtual device

• Peripheral device

• Logical device

Sequential access storage media stores data:

• Record by record in sequence

• Randomly

• By block numbers

• By file names

Which of the following is an example of sequential access storage?

• Hard disk

• Magnetic tape

• Flash memory

• Optical disc

The interrecord gap (IRG) is:

• The space between two records on magnetic tape

• The time needed to transfer records

• The distance between tracks

• The time delay between blocks

Blocking records on tape helps improve efficiency by:

• Increasing seek time

• Reducing I/O operations

• Slowing down transfer rates

• Eliminating parity bits

Devices that allow both sequential and direct access are called:

• Direct Access Storage Devices (DASD)

• Sequential Devices

• Virtual Devices

• Peripheral Devices

Which is not a type of DASD?

• Magnetic disk

• Optical disk

• Flash memory

• Magnetic tape
