Can you explain what is meant by synchronous communication between system components?

Synchronous communication between system components means that when interacting, one component calls another and waits for its completion before continuing.

This means the calling component is blocked until it receives a response or result from the called component.

Example: in Java, method A calls method B, and method A will not continue until method B returns a result.

This is convenient when you need to obtain data or perform an action sequentially, but it can lead to delays if the called component takes a long time to work or is unavailable.

Unlike asynchronous communication, where the call occurs without waiting for a result, and components work in parallel.
