Request-Response
Request-Response is a fundamental communication pattern in computing where one system (the client) sends a request to another system (the server), and the server processes that request and returns a response. It is the core model underlying most client-server architectures, including web applications, APIs, and distributed systems. This pattern defines how data is exchanged between components, typically over networks using protocols like HTTP, gRPC, or WebSockets.
Developers should learn and use the Request-Response pattern because it is essential for building interactive applications, such as web services, mobile apps, and microservices, where clients need to fetch or send data to servers. It is critical for implementing RESTful APIs, handling user interactions in web development, and ensuring reliable communication in distributed systems, making it a foundational skill for backend and full-stack development.
