Asynchronous vs Synchronous Execution

What is the difference between asynchronous and synchronous execution?

In a systematic process, asynchronous execution is moving on another task before the earlier one finishes. On the other hand in synchronous execution is moving on another task only after finishing the earlier one.

Asynchronous vs Synchronous Execution

Almost every modern-day application is made asynchronous in order to make things load quicker and snappier, in result, users have to wait for less to see the user interface.

Execution

When you have to load a lot of resources in less time, asynchronous execution is a must.

Let’s see a code-based visual representation of Asynchronous vs Synchronous execution.

Just understand a few basics:

  • |---A---| is a process in a thread.
  • --- is a continuation in an existing thread.
  • |---| is a wait in an existing thread.
  • \ is a notation for the next process.

Asynchronous Execution

In a single-threaded work environment…

Thread 1 |<-A-|<--B--|<-C-|-A-|-C-|-A-|-B-|-C->|-A->|--B-->|END

In a multi-threaded work environment…

Thread A |<---A---->|
            \
Thread B ---|<----B---------->|
               \
Thread C -------|<------C--------->|END

Synchronous Execution

In a single-threaded work environment…

Thread 1 |<----A---->||<----B-------->||<----C------------>|END

In a multi-threaded work environment…

Thread A |<---A---->|   
                     \  
Thread B |-----------|<----B---------->|   
                                        \   
Thread C |-------------------------------|<------C----->|END

We have seen an overview of both, so what would be better?

In all the test scenarios, asynchronous execution is better and almost every new technology is using it. The asynchronous method utilizes more processing power than synchronous, but for a very shorter time and then sits ideal.

Whereas synchronous execution is only good for small or classical applications, the modern application uses a lot of files and synchronous loading causes a wait there.

This is all about asynchronous and synchronous execution.
