CST306 Topic 3

What is the primary function of an operating system in relation to processes?

• Designing hardware

• Managing user interface only

• Creating, managing, and terminating processes

• Writing application code

Which of the following uniquely characterizes a process while executing?

• File type

• Process Control Block (PCB)

• Queue time

• CPU speed

What are the two essential elements of a process?

• I/O and Memory

• Code and Stack

• Threads and cores

• Program code and associated data

Which process state indicates a process is waiting for an event to occur?

• Ready

• Running

• Blocked

• Terminated

What is the reason for using multiple blocked queues?

• To increase the memory usage

• To eliminate scheduling

• To store completed processes

• To organize blocked processes based on events

When a process is moved from memory to disk temporarily, it is called:

• Swapping

• Scheduling

• Spooling

• Paging

A suspended process is characterized by:

• Being always ready to execute

• Immediate availability

• Lack of a parent process

• Inaccessibility until explicitly resumed

Which is a more privileged execution mode in an OS?

• User mode

• Application mode

• Kernel/System mode

• Hypervisor mode

Which structure is vulnerable to corruption by a faulty OS routine and affects process management?

• Memory Map

• I/O Table

• Queue

• Process Control Block (PCB)

What is the OS’s main challenge with the Process Control Block (PCB)?

• Access speed

• Location

• Protection and structural consistency

• Naming conventions
