OS QUIZ1

Which of the following is NOT a primary function of an Operating System?

• Memory management

• Process management

• Database management

• File system management

Which statement accurately describes a thread in an operating system?

• A thread is a lightweight process that shares resources like memory with other threads within the same process.

• A thread is a sequence of instructions executed by the operating system itself.

• A thread is an independent program that runs separately from other programs.

• A thread manages the hardware resources of the system

Which of the following is NOT a type of operating system?

• Batch operating system

• Real-time operating system

• Web-based operating system

• Distributed operating system

What is the main characteristic of a multiprogramming operating system?

• It executes one process at a time, but switches between processes to maximize CPU utilization

• It allows for real-time execution of tasks in parallel

• It executes multiple processes at the same time using multiple CPUs.

• It can run processes based on priority and scheduling.

A real-time operating system (RTOS) is specifically designed to:

• Handle large data storage and processing tasks.

• Ensure that tasks are completed within a strict time constraint.

• Support multitasking for general-purpose computing.

• Run on distributed networks.

Which of the following describes a distributed operating system?

• Which of the following describes a distributed operating system?

• It is designed specifically for mobile and embedded devices.

• It provides users with access to a single computer from multiple locations

• It integrates multiple computers to work as a unified system, offering a single view of resources

What happens during a context switch in an operating system?

• The current process is paused, and its resources are freed.

• The system starts a new process and kills the old one.

• The CPU switches between user mode and kernel mode.

• The CPU switches from one process to another, saving and loading their context.

In the Producer-Consumer Problem, what condition must be satisfied to avoid inconsistency?

• The producer should only produce if there is space available in the buffer

• There must always be a fixed amount of data in the buffer

• The consumer should only consume if the buffer is empty

• Both producer and consumer must execute simultaneously

What is a semaphore used for in process synchronization?

• To manage process priorities

• To directly control the CPU allocation to processes

• To avoid deadlock by ensuring that processes access shared resources in a specific order

• To signal processes that they can proceed after waiting for a shared resource
  

The Critical Section Problem occurs when:

• A process can only execute in user mode

• The system is unable to allocate resources due to deadlock

• Multiple processes access shared resources simultaneously and interfere with each other
  

• The CPU cannot schedule tasks based on priority
