Polling I/O vs Event Loop
Developers should learn polling I/O for scenarios where simplicity and control are prioritized over efficiency, such as in embedded systems with limited hardware support, real-time applications requiring deterministic timing, or when implementing lightweight protocols in low-resource environments meets developers should learn event loops when building applications that require high concurrency and responsiveness, such as web servers, real-time systems, or gui-based software, to avoid blocking operations and improve performance. Here's our take.
Polling I/O
Developers should learn polling I/O for scenarios where simplicity and control are prioritized over efficiency, such as in embedded systems with limited hardware support, real-time applications requiring deterministic timing, or when implementing lightweight protocols in low-resource environments
Polling I/O
Nice PickDevelopers should learn polling I/O for scenarios where simplicity and control are prioritized over efficiency, such as in embedded systems with limited hardware support, real-time applications requiring deterministic timing, or when implementing lightweight protocols in low-resource environments
Pros
- +It's useful when dealing with simple devices that lack interrupt capabilities or in educational contexts to understand basic I/O handling, but it's generally avoided in high-performance systems due to its CPU-intensive nature and potential for latency
- +Related to: asynchronous-io, event-driven-programming
Cons
- -Specific tradeoffs depend on your use case
Event Loop
Developers should learn event loops when building applications that require high concurrency and responsiveness, such as web servers, real-time systems, or GUI-based software, to avoid blocking operations and improve performance
Pros
- +It's essential for mastering asynchronous programming in languages like JavaScript (Node
- +Related to: asynchronous-programming, non-blocking-io
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Polling I/O if: You want it's useful when dealing with simple devices that lack interrupt capabilities or in educational contexts to understand basic i/o handling, but it's generally avoided in high-performance systems due to its cpu-intensive nature and potential for latency and can live with specific tradeoffs depend on your use case.
Use Event Loop if: You prioritize it's essential for mastering asynchronous programming in languages like javascript (node over what Polling I/O offers.
