Which of the following accurately describes the relationship between processes, threads, and cores?
- A thread lives in a core, a core lives in a process, and a process lives in a CPU.
- A core lives in a thread, a thread lives in a process, and a process lives in a CPU.
- A process lives in a thread, a thread lives in a core, and a core lives in a CPU.
- A thread lives in a process, a process lives in a core, and a core lives in a CPU. (correct)
In the context of computer processing, what is the primary difference between multiprocessing and multithreading?
In the context of computer processing, what is the primary difference between multiprocessing and multithreading?
- Multiprocessing uses multiple independent processors or CPU cores to execute tasks, whereas multithreading involves multiple threads within a single process. (correct)
- Multiprocessing uses multiple threads within a single process, whereas multithreading utilizes multiple independent processors or CPU cores.
- Multiprocessing is only for operating systems, while multithreading is only for applications.
- Multiprocessing uses multiple programs, while multithreading executes a single program.

Study Notes
- A processor, or central processing unit (CPU), is the core component of a computer.
- The processor executes instructions and manages data manipulation based on those instructions.
- A multi-core processor contains two or more independent processing cores on a single chip.
- Multitasking is the ability of an operating system to manage and execute multiple tasks concurrently.
- Multiprocessing involves the use of multiple independent processors or CPU cores to execute tasks.
- Multithreading is a technique where a single process contains multiple threads of execution.
- A program is a set of instructions written in a programming language, which is designed to be executed by a computer.
- A program needs at least one thread to run.
- A process is an independent, executing instance of a program in a computer's memory.
- A process includes the code, data, system resources, and execution context needed for a program to run.
- A thread is a unit of execution within a process in a computer's operating system.
- Processes have the largest resource and memory overhead.
- Threads are lighter and offer shared memory space.
- Coroutines have the least overhead.
- A coroutine lives in a thread, a thread lives in a process, and a process lives in a core, which is part of a CPU.
