Define RESTful APIs and explain how they facilitate communication between client and server.

RESTful APIs: Definition and Communication Facilitation Definition: RESTful (Representational State Transfer) APIs (Application Programming Interfaces) are a set of architectural principles and constraints that guide the design and development of web services. REST is not a protocol but a style of building networked applications. The term "RESTful" is commonly used to describe web services that adhere to these principles. *Key Principles of REST: 1. Statelessness: - Explanation: Each request from a client to a server contains all the information needed to understand and fulfill that request. The server does not store any client state between requests. This enhances scalability and simplifies the architecture. 2. Resource-Based: - Explanation: Resources, such as data entities or services, are identified by URIs (Uniform Resource Identifiers). In a RESTful API, everything is considered a resource, and these resources can be manipulated using standard HTTP methods. 3. Representation: - Explanation: Resources can have multiple representations (e.g., JSON, XML, HTML), and the client negotiates the representation it wants. The server sends data to the client in a format that the client can understand. 4. Uniform Interface: - Explanation: A uniform and consistent set of constraints simplifies interactions between clients and servers. This includes a common set of methods (HTTP verbs), resource identification through URIs, self-descriptive messages, and hypermed....
