Identification Quiz: Network and Device Management

What is a dedicated device?

• A device shared among multiple processes

• A device assigned to only one job at a time

• A logical device for virtual memory

• A device optimized for multitasking

Which type of device can serve multiple active processes simultaneously?

• Dedicated device

• Shared device

• Virtual device

• Sequential device

What does a virtual device represent?

• A logical device created using spooling

• A device optimized for multitasking

• A physical device limited to one process

• A randomly accessible medium

Which storage medium is classified as sequential access?

• Hard disk

• Magnetic tape

• Flash drive

• Optical disc

What type of device is DASD (Direct Access Storage Device)?

• Devices storing data sequentially

• Devices with direct read/write access to specific locations

• Devices relying on virtual spooling

• Devices using optical reflections

What does FCFS stand for in scheduling?

• Fixed Circular Frame Selection

• First-Come, First-Served

• Fast Channel Forward Strategy

• File Copy First Sequence

Which algorithm prioritizes requests based on proximity to the current track?

• SCAN

• SSTF (Shortest Seek Time First)

• FCFS

• LOOK

Which scheduling strategy minimizes arm movement by scanning in one direction?

• LOOK

• SCAN

• C-SCAN

• N-Step SCAN

The C-SCAN algorithm is also called:

• Elevator algorithm

• Circular SCAN

• Proximity-based scan

• Deferred rotational order

What is the main advantage of the LOOK algorithm over SCAN?

• Avoids unnecessary arm movement

• Processes farthest requests first

• Reduces response time variance

• Simplifies implementation
