It is a section of code where the processor gives priority to execute multiple threads simultaneously.

It is a section of code where hardware interrupts are disabled to ensure uninterrupted execution.

It is a part of the kernel where system-level processes are given higher priority over user-level processes.

In the Windows OS, which statement is true about the blocked state of a process?

Waiting to input/output and Waiting for an event that has not happened yet

Waiting for an event triggered by the CPU's scheduling mechanism

Waiting for an event that has not happened yet

The CPU and Memory are waiting to other events

When using the Critical Regions solution, which of the following conditions is NOT necessary?

Processes entering critical regions must set their speed or number of CPUs.

Two processes are not in critical regions at the same time.

A process outside the staging area must not prevent other processes from entering critical regions.

Processes do not have to wait indefinitely to enter critical regions.

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

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 used to store temporary files created by applications to free up physical RAM.

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.

What is segmentation with paging, and how does it enhance memory management?

A method that combines the flexibility of segmentation with the efficiency of paging.

A technique for managing multiple memory segments simultaneously.

A scheme that uses fixed-size pages to allocate memory.

A scheduling algorithm for thread management.

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

What does the term "blocking" refer to in the context of I/O software?

The process of stopping a process until an I/O operation is completed.

A technique for managing device drivers.

A mechanism for ensuring device synchronization.

A method of allocating memory for I/O operations.

Which of the following is NOT a responsibility of Device-Independent I/O Software layer?

Allocating port numbers to I/O devices

Uniform interfacing for device drivers

Allocating and releasing dedicated devices

Providing a device-independent block size

Which of the following is NOT one of the usual duties of Clock Software?

Helping processes in running longer than they are allowed to.

Handling the alarm system call made by user processes.

Doing profiling, monitoring, and statistics gathering.

In a thin client setup, where is most of the software and data processing performed?

On a central server or ud infrastructure.

Locally on the thin client device.

On a central server or client infrastructure

Which of the following statements regarding deadlock is correct?

A combination of semaphore and mutex ensures safe resource allocation.

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

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

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

What is a preemtable resource?

The one that can be taken away from the process owning it with no ill effects

The one that can be taken away from the process owning it with ill effects

The one that can not be taken away from the process owning it with no ill effects

The one that can not be taken away from the process owning it with ill effects

In deadclock, what is no-preemption condition?

Resources previously granted cannot be forcibly taken away from a process. They must be explicitly released by the process holding them.

Processes currently holding resources that were granted earlier can request new resources.

There must be a circular list of two or more processes, each of which is waiting for a resource held by the next member of the chain.

Each resource is either currently assigned to exactly one process or is available.
