Task vs. Thread in C#

Understanding the difference between Task and Thread in C#

Task vs. Thread in C#

Hi Devs, Developers often work with both Tasks and Threads to handle asynchronous operations and manage parallelism in C#. However, understanding when to use each and how they work is important for writing efficient code. This article will discuss Tasks and Threads, comparing their differences, benefits, and best practices.

1. What is a Thread?

A Thread is the smallest unit of execution in a program. You will ask the operating system to run a separate process within your application to create the thread. Imagine that thread is like a way to divide work so that different parts of your program can run simultaneously.

Key Features of Threads

• Independent Execution: Threads operate independently, meaning one thread can continue its work even if another one is busy or blocked.
• Manual Control: You create and manage threads manually. This means you are responsible for starting, stopping, and handling each thread’s lifecycle.
• Heavyweight: Threads take up a lot of system resources because they have their own stack, memory, and other resources.
