When developing applications, understanding how tasks interact with your system's resources is essential to optimize performance. One of the most important distinctions in performance tuning is between CPU-bound and I/O-bound operations. Knowing the difference allows you to make informed decisions about improving responsiveness, scalability, and efficiency in your software. This article will guide you through the concepts of CPU-bound and I/O-bound tasks, providing detailed examples and code demos to help you grasp how each operates in real-world scenarios.
