Operating Systems Quiz

Which of the following best differentiates multiprogrammed batch systems from time-sharing systems?

• CPU utilization

• User interaction

• Process scheduling algorithm

• Memory allocation strategy

In a simple batch system, jobs are executed:

• Interactively with user commands

• One after another in arrival order

• Simultaneously in memory

• By priority scheduling only

The major drawback of simple batch systems compared to multiprogramming is:

• High throughput

• Idle CPU during I/O wait

• Complex scheduling

• Excessive user interaction

In a parallel system, the failure of one processor:

• Always halts the entire system

• May halt the system unless fault tolerance exists

• Has no effect at all

• Automatically improves performance

Which of the following is the biggest challenge for a distributed OS?

• CPU scheduling

• Consistency and transparency

• Cache memory utilization

• Multiprogramming level

A real-time OS is distinguished by:

• High throughput

• Guaranteed response time

• Support for multiprogramming

• Use of batch scheduling

Which OS type is most suitable for a hospital monitoring system?

• Time-sharing OS

• Distributed OS

• Real-time OS

• Batch OS

The OS as a resource manager primarily manages:

• Hardware, software, and users

• Compiler and interpreter only

• Database and files only

• Applications only

A multi-processor system may suffer from which main issue?

• Increased throughput

• Shared resource contention

• Reduced fault tolerance

• High response time

Which system must strictly handle timing constraints?

• Distributed systems

• Real-time systems

• Personal-computer systems

• Parallel systems
