What is referred to as multiprocessing?

• The ability to execute processes in a sequential manner

• The ability to execute a single process

• The ability to execute multiple threads in a single process

• The ability to execute multiple processes simultaneously

What are systems capable of performing multiprocessing known as?

• Cooperative systems

• Single processor systems

• Multiprocessor systems

• Multitasking systems

What does multitasking refer to?

• Executing a single process

• Running multiple threads in a single process

• Executing multiple processes simultaneously

• Holding multiple processes in memory and switching between them

What is context switching?

• Switching between different CPUs

• Switching of execution context from one task to another

• Saving the state of a process

• Loading a process into memory

What is the primary difference between multiprocessing and multitasking?

• Multiprocessing involves multiple CPUs, multitasking does not

• Multitasking is faster than multiprocessing

• Both are the same

• Multiprocessing is a type of multitasking

What is cooperative multitasking?

• Tasks run until completion without yielding

• Tasks voluntarily relinquish the CPU

• Tasks are executed in a random order

• Tasks are preempted by the OS

What is preemptive multitasking?

• Tasks run until they complete

• Tasks are executed based on priority

• Tasks are executed in a sequential manner

• Tasks voluntarily yield the CPU

What is a thread?

• A lightweight process

• A type of CPU

• A memory allocation technique

• A type of operating system

What is the main advantage of using threads?

• Increased complexity

• Slower execution

• Better memory utilization

• Increased memory usage

What is a hard real-time system?

• A system that is not time-sensitive

• A system that can miss deadlines

• A system that must meet deadlines without slippage

• A system that allows for human intervention
