The concepts of asynchronous and synchronous programming

[Symasoiti97]

What do you think about my thoughts?

Synchronicity and asynchronicity describe the way two or more actions are executed in relation to each other.

Defining Actions:

When discussing synchronicity or asynchronicity in programming, we need to define these actions:

• Waiting for the result of a task.
• Executing the task we are waiting for (e.g., making a request, reading a file).

How It Works in Practice

In Synchronous Code:

• The thread waits until the task it is expecting is completed. In other words, waiting happens synchronously (at the same time) as the execution of the task itself. The waiting is performed by our application's thread, while the task being waited for can be executed either by our thread or by another process.

In Asynchronous Code:

• The thread is freed and can take on another task. This means that waiting occurs asynchronously (not at the same time) relative to the execution of the task itself.

---

Conclusion:

• Synchronicity is when waiting and the task being awaited occur at the same time, meaning synchronously.
• Asynchronicity is when waiting and the task being awaited do not occur at the same time, meaning asynchronously.

Asynchronous programming allows a thread that is waiting for a task to complete to be freed up so it can perform other useful work.

Maybe you wanted to ask why exactly the terms "synchronous" and "asynchronous" were chosen?

[Symasoiti97]

I wanted to answer on this question and I wanted to ask if I'm right

Synchronicity is when the waiting and the task being awaited occur at the same time, meaning synchronously.
Asynchronicity is when the waiting and the task being awaited occur NOT at the same time, meaning asynchronously.

Synchronous - you call a person, ask a diffciult question and wait for an answer while holding a phone and occupying your hands.

Asynchronous - you call a person, ask a difficult question and tell to call you back when there is an answer. Meanwhile you do other things and resume the conversation when that other person is ready

[Symasoiti97]

You provided an example, but I would like to see the definition of these terms.
For me, synchronous (or asynchronous) is the relationship between actions.

What are these actions in your example?
