RESTful APIs and web services are essential components of modern software development, facilitating communication and data exchange between different applications and systems over the internet.

RESTful APIs: These APIs adhere to the principles of the REST architectural style, using standard HTTP methods to perform operations on resources. They enable the creation, retrieval, updating, and deletion of data, and are widely used due to their simplicity and compatibility with various programming languages.

Web Services: Web services encompass various technologies and protocols that enable applications to communicate and interact across different platforms. SOAP and REST are common web service types. SOAP focuses on providing a strict contract for data exchange using XML, while REST emphasizes a more lightweight and flexible approach using standard HTTP methods.

Both RESTful APIs and web services are integral to building interconnected applications that can seamlessly share data and functionality, contributing to the overall efficiency and interoperability of modern software systems.
