2.3.2.4. Concurrent & Parallel Programming

Try these first

1. 1.

   Define the term 'Concurrency'.

   Hint

   Think about how multiple tasks are interleaved.

2. 2.

   What is a Thread?

   Hint

   Consider how threads operate within a single application.

3. 3.

   What is the main purpose of concurrency?

   • To run tasks simultaneously
   • To manage multiple tasks
   • To improve memory usage

   Hint

   Think about multitasking.

4. 4.

   True or False: Parallelism can be achieved with multiple threads within a single process.

   • True
   • False

   Hint

   Consider processors and threads.

5. 5.

   Given a multithreaded application performing database transactions, discuss potential race conditions and propose a synchronization method to prevent them.

   Hint

   Consider how access is shared among threads.

6. 6.

   Design a simple multithreaded program that counts how many times a particular number appears in a large list. Explain how you would implement parallel processing.

   Hint

   Think about how the workload can be split.
