Threads and Multithreading

 

 

What is a Thread?

• A thread is the smallest unit of execution within a process.
• A single process can have multiple threads.
• Unlike processes, which each have their own code, data, and heap,threads share the code, data, and heap of their process. → This allows multiple tasks to run concurrently within a single process.

Multithreading

• Multithreading is a technique where multiple threads within a process share the workload.
• Since threads share memory and resources, it is more efficient in terms of memory usage, faster than inter-process communication, and generally provides better performance.
