Speaker
What is the main purpose of an I/O system?
Increase screen resolution
Handle power management
Manage communication between hardware and software
Improve CPU clock speed
What is buffering in I/O management?
Deleting unused files
Printing documents
Temporarily storing data during transfer
Compressing files
Which I/O management technique allows multiple jobs to share the same device?
Buffering
Caching
Spooling
Swapping
Which of the following is a block device?
Mouse
Printer
Hard disk
Keyboard
In disk scheduling, which algorithm services the request with the shortest seek time first?
FCFS
SSTF
SCAN
LOOK
Which device is an example of a communication device?
SSD
RAM
Network Card
CPU
What does asynchronous I/O mean?
Data is transferred using real-time clocks
Sender waits for receiver
Data is transferred independently, without waiting
Devices must operate on the same frequency
What is the primary function of a device driver?
Improve graphics
Interface between hardware and the OS
Boost memory
Encrypt files
Which disk scheduling algorithm behaves like an elevator moving up and down floors?
FCFS
SSTF
SCAN
C-SCAN
What type of access is used in tape drives?
Random access
Direct access
Parallel access
Sequential access
Which of the following is not part of I/O management?
Buffering
Spooling
Caching
Paging
Which I/O scheduling goal ensures that no request waits indefinitely?
Throughput
Fairness
Seek time reduction
Real-time access
What does LOOK algorithm do that SCAN doesn't?
Ignores request direction
Reverses direction at ends of the disk
Avoids going to the end of the disk if no request exists
Sorts requests randomly
Which of the following best describes C-SCAN?
Services requests in order of arrival
Moves back and forth over the disk
Wraps around the disk in a circular pattern
Services shortest job first
The primary goal of I/O systems is to directly access CPU registers.
TRUE
FALSE
SSDs typically benefit from disk scheduling algorithms.
TRUE
FALSE
Caching helps reduce the need for repeated access to slow devices.
TRUE
FALSE
Spooling is typically used in print systems.
TRUE
FALSE
In asynchronous I/O, the system must wait for one operation to finish before starting another.
TRUE
FALSE
