Synchronous and asynchronous communications refer to two different methods of communication between software components or systems, each with its own characteristics and use cases.

Synchronous communication involves blocking and waiting for immediate responses, while asynchronous communication enables non-blocking and decoupled interactions between software components, offering benefits such as improved scalability, responsiveness, and concurrency. The choice between synchronous and asynchronous communication depends on the specific requirements and characteristics of the system or application.
