Can you explain what is meant by 'stream' in programming?

In programming, a "thread" refers to a sequence of instructions executed within a process. A thread is the smallest unit of CPU utilization that can run concurrently with other threads within the same process.

Each thread has its own call stack and registers but shares memory and resources with other threads of the process, which allows for efficient data exchange. Threads are often used to implement parallelism and improve performance, for example, for simultaneous processing of multiple tasks.

An example of creating a thread in Python using the threading module:

import threading

def worker():
    print("Thread is running")

thread = threading.Thread(target=worker)
thread.start()
thread.join()
