What is a key characteristic that distinguishes a process from a thread?
What is a key characteristic that distinguishes a process from a thread?
- Threads are heavier than processes.
- Processes are isolated and have their own memory and resources. (correct)
- Threads have their own independent memory space.
- Processes share resources with other processes.
Which of the following correctly defines a thread?
Which of the following correctly defines a thread?
- A thread is an independent program with its own resources.
- A thread operates in isolation, similar to a process.
- A thread cannot run independently.
- A thread is the smallest unit of execution within a process. (correct)
What is the major advantage of using threads in an application?
What is the major advantage of using threads in an application?
- Threads operate without any communication between them.
- Context switching between processes is faster than between threads.
- Threads require more memory than processes.
- Threads make it easier to parallelize tasks within an application. (correct)

Study Notes
Process
- Definition: An independent program running, with its own memory and resources allocated by the operating system.
- Characteristics:
- Has its own memory (separate address space).
- Isolated from other processes.
- Context switching between processes is resource-intensive.
Thread
- Definition: The smallest execution unit within a process, sharing the process's resources.
- Characteristics:
- Shares memory and resources with other threads within the same process.
- Context switching is faster.
- Considered a lightweight process because multiple threads can exist in one process.
- Efficient for parallel data execution, like handling user interactions and background tasks.
Summary
- Process: An independent execution unit with its own memory and resources.
- Thread: A lightweight execution unit sharing memory and resources within a process.
