CHAPTER 3: OPERATING SYSTEM STRUCTURES

Which of the following statements is true about processes and programs?

• A program is an active entity that utilizes resources during execution

• A process is a passive entity represented by the contents of a file

• A single-threaded process has multiple program counters to specify the next instructions

• A process is an active entity that utilizes resources during execution

"Allocate and de-allocate memory space as needed". This statement is part of the OS activities in...

• memory management

• process management

• file management

• protection system

Which of the following is not an activity of the operating system in file management?

• Create and delete files

• Compile and debug files

• Map files onto secondary storage

• Back up files on stable storage media

Storage allocation in disk management primarily involves:

• Assigning storage blocks to files and directories

• Allocating memory to processes

• Optimizing CPU usage during I/O operations

• Encrypting data on the disk

Which of the following is not a component of the I/O subsystem?

• A memory-management component for buffering, caching, and spooling

• A general device-driver interface

• Drivers for specific hardware devices

• Process scheduling for CPU operations

Which of the following statements about protection mechanisms is true?

• Protection ensures a system is completely free from failures

• Protection mechanisms only control physical access to resources

• Protection improves reliability by detecting errors at component interfaces

• Protection eliminates the possibility of inappropriate access entirely

What is a key consideration when designing a communication network for distributed systems?

• Minimizing memory allocation for processes

• Managing routing and connection strategies

• Reducing the number of nodes in the network

• Limiting access to shared resources to avoid computation

What is the primary role of the command interpretation system in an operating system?

• Managing hardware resources like CPU and memory

• Establishing network connections between devices

• Allocating storage for files and directories

• Interpreting and executing user commands

Which of the following statements is true about a monolithic kernel?

• The operating system operates entirely in user space in user mode

• Device drivers cannot be added to the kernel in a monolithic kernel

• A monolithic kernel implements all OS services through system calls and primitives

• The monolithic kernel lacks a supervisor mode for system operations

What is the primary advantage of using a layered structure in operating system design?

• It eliminates the need for a user interface

• It ensures all system components run in supervisor mode

• It removes the dependency on hardware resources

• It simplifies debugging and system maintenance
