What is the principle of operation of synchronous interaction methods between system components?

Synchronous interaction methods between system components operate on the principle of direct invocation, where the calling component pauses its execution and waits until the called component completes processing and returns a result. This means that the execution thread is blocked until a response is received.

For example, in Java, when calling a method of another object, the current thread's execution stops until the method finishes and returns a value or throws an exception.

This approach is convenient when you need to get the result immediately and continue working with it, but it can lead to blocking and reduced performance if the called method takes a long time to execute.
