QUIZ- OSG - PART 3

Which of the following statements regarding deadlock is correct?

• Allocation is a logical process while acquisition is its physical implementation.

• Banker’s Algorithm is used to guarantee absolute mutual exclusion during resource acquisition.

• A combination of semaphore and mutex ensures safe resource allocation.

• Kernel is responsible for exclusive resource acquisition by a process while IPC takes care of safe resource allocation among multiple processes.

Which of the following actions does the operating system take to execute a new process?

• Provide immediate CPU for process.

• Delivery the resources must be process

• Create immediate PCB blocks for process.

• Provide immediate Register for process.

Which of the following best describes the relationship between threads within a single process?

• Threads are completely independent and do not share any resources.

• Threads share the same memory space but have their own registers.

• Threads are separate and isolated from one another.

• Threads are tightly integrated, and they all have their own separate memory space.

Which of the following best describes the difference between a process and a thread in the context of the Windows operating system?

• A process contains multiple threads and shares resources, while a thread is an independent execution unit within a process.

• A process is a program in execution, while a thread is a sequence of instructions that can execute independently.

• A process and a thread are essentially the same in Windows OS, with no significant difference between them.

• A process represents system resources, while a thread is responsible for user interface interactions in Windows OS.

Which statement best describes the function of virtual memory in the Windows operating system?

• Virtual memory is used to store temporary files created by applications to free up physical RAM.

• Virtual memory allows a larger address space than the physical memory available, by using a combination of RAM and hard disk space.

• Virtual memory is a reserved area on the hard disk used exclusively for storing system files.

• Virtual memory enables the operating system to manage the computer’s display settings for multiple monitors.

Which scenario would the FIFO (First-In-First-Out) page replacement algorithm suffer from the "Belady's Anomaly"?

• When the number of frames allocated to a process exceeds the number of pages

• When the number of frames allocated to a process is less than the number of pages

• When the number of frames allocated to a process remains constant over time

• When the number of frames allocated to a process varies randomly

Which condition among the four conditions for deadlock is described by "Each resource is either currently assigned to exactly one process or is available"?

• Mutual exclusion condition.

• Hold-and-wait condition.

• No-preemption condition.

• Circular wait condition.

How does memory abstraction through address spaces benefit a computer system?

• It allows each process to access the entire physical memory directly.

• It isolates processes from one another, preventing unauthorized access.

• It eliminates the need for virtual memory.

• It reduces CPU processing speed.

An operating system. In bitmap image processing, what does each bit typically represent?

• A single pixel's color

• A sequence of characters

• A data packet in network transmission

• A unit of storage capacity

Consider two statements:

Statement 1: A Log-structured File System (LFS) is a design for file systems in which all changes to the file system's state are appended sequentially to a log. This innovative approach contrasts with traditional file systems, which often overwrite blocks in place to update files or file metadata.
Statement 2: Journaling File System: first writes a log entry listing the three actions to be completed. The log entry is then written to disk. Only after the log entry has been written, do the various operations begin.

Choose the correct option

• Statement 1 is true, statement 2 is true

• Statement 1 is false, statement 2 is false

• Statement 1 is true, statement 2 is false

• Statement 1 is false, statement 2 is true
