Explain the difference between Synchronous and Asynchronous programming.
Answer:
- Synchronous Programming:
- In synchronous programming, tasks are executed sequentially, one after the other, and each task must wait for the previous one to complete before starting.
- It is easier to understand and debug since the code executes line by line.
- However, synchronous operations may lead to blocking, especially in I/O-bound tasks, where the program waits for external resources (e.g., network requests, file I/O).
- Asynchronous Programming:
- In asynchronous programming, tasks can run concurrently, allowing multiple tasks to execute independently and potentially overlap in time.
- It improves performance and responsiveness by allowing the program to continue executing other tasks while waiting for slow I/O operations to complete.
- Asynchronous operations typically use callbacks, promises, or async/await syntax to handle results and errors asynchronously.
