Differentiate between a process and a thread.

Question

Accepted Answer

A process is an instance of a program while a thread is a subset of a process.

A process has its own memory space while threads share memory space
Processes are heavyweight while threads are lightweight
Processes communicate through inter-process communication while threads communicate through shared memory
Examples of processes include web browsers, text editors, etc. while examples of threads include GUI updates, background tasks, etc.

### **Process vs. Thread: Key Differences** A **process** and a **thread** are fundamental concepts in computing, particularly in operating systems. Here’s how they differ: | Feature | Process | Thread | |---------|---------|--------| | **Definition** | A process is an independent program in execution. | A thread is a lightweight unit of execution within a process. | | **Memory Sharing** | Processes have separate memory spaces. | Threads share memory within the same process. | | **Communication** | Inter-process communication (IPC) is required. | Threads communicate easily via shared memory. | | **Creation Time** | Takes more time to create. | Faster to create than a process. | | **Context Switching** | More overhead due to separate memory. | Faster context switching since threads share resources. | | **Isolation** | Processes are independent and isolated. | Threads within a process are interdependent. | | **Example** | Running multiple applications (e.g., browser, text editor). | Multiple tasks within an application (e.g., tabs in a browser). | Threads allow efficient multitasking within a process, while processes provide isolation and security.

प्रक्रिया निष्पादन में एक प्रोग्राम है, जबकि थ्रेड प्रक्रिया का एक खंड है। एक प्रोग्राम जो चल रहा है। अन्य प्रक्रियाओं से अलग। अन्य प्रक्रियाओं से अधिक स्वतंत्र। संचार अधिक जटिल और धीमा है। थ्रेड प्रक्रिया का एक खंड है जिसे निष्पादन के लिए शेड्यूल किया जा सकता है। अन्य थ्रेड से अलग नहीं। प्रक्रिया के भीतर अन्य थ्रेड पर निर्भर। संचार तेज और कुशल है।

Accepted Answer

A process is a program in execution, while a thread is a segment of a process. A program that is running. Isolated from other processes. More independent of other processes. Communication is more complex and slower. 
Thread is a segment of a process that can be scheduled for execution. Not isolated from other threads. Dependent on other threads within a process. Communication is fast and efficient.
