Difference between processes and Thread

Processes vs Threads

Processes

• Independent execution unit
• Own memory space
• Heavyweight, requires significant resources
• Uses Inter-Process Communication (IPC) mechanisms
• Independent, if one process crashes, others are not affected

Threads

• Lightweight process
• Shares memory space with other threads
• Lightweight, requires fewer resources
• Can communicate directly
• Dependent on parent process, if one thread crashes, the entire process may be affected

Key Differences

• Memory Space: Processes have their own memory space, while threads share the same memory space.
• Resource Utilization: Processes are more resource-intensive, while threads are less resource-intensive.
• Creation Time: Processes take longer to create, while threads are faster to create.
• Communication: Processes use IPC mechanisms, while threads can communicate directly.
• Fault Tolerance: Processes are more fault-tolerant, while threads are less fault-tolerant.
