4.7. Concurrent and Parallel Programming Paradigm

Try these first

1. 1.

   What is the difference between concurrency and parallelism?

   Hint

   Think about whether tasks are done at the same time or just managed at the same time.

2. 2.

   Name one advantage of concurrent programming.

   Hint

   Consider how tasks interact.

3. 3.

   What is the primary difference between concurrency and parallelism?

   • Concurrency means tasks are done at the same time.
   • Parallelism involves overlapping tasks.
   • Concurrency is about managing multiple tasks
   • while parallelism is about executing them simultaneously.

   Hint

   Think about whether tasks can overlap or must be done at the same time.

4. 4.

   True or False: Multithreading can help improve program performance.

   • True
   • False

   Hint

   Consider how servers handle multiple requests.

5. 5.

   Design a simple thread-safe program in Python that increments a shared variable from multiple threads without race conditions. Explain your code.

   Hint

   Think about how to restrict access while avoiding deadlocks.

6. 6.

   Imagine a scenario where you need to fetch data from a database and process it. Propose how you'd leverage both asynchrony and multithreading in your implementation.

   Hint

   Factor in the nature of I/O operations versus computational tasks.
