Master Java Web Services and REST API with Spring Boot- What is a Web Service?

The video tutorial explains the concept of web services, highlighting their definition and characteristics. It discusses the challenges of application-to-application interaction, particularly when using HTML for data exchange. The tutorial emphasizes the importance of interoperability, machine-to-machine interaction, and network communication in web services. It concludes by summarizing the key points and setting the stage for future learning on building web services.

What is a web service primarily designed for?

• Human interaction

• Application-to-application interaction

• Delivering HTML output

• Rendering data on a screen

Why can't the HTML output of the to-do application be used directly by another application?

• HTML is not compatible with Java applications

• HTML is not secure

• HTML is too complex to parse

• HTML is not designed for machine-to-machine interaction

What is a potential issue with using a jar file to share business logic?

• It cannot be updated

• It needs a database and other dependencies

• It requires a specific operating system

• It is too large to distribute

What is the W3C definition of a web service?

• A service that delivers HTML over the internet

• A software system for interoperable machine-to-machine interaction over a network

• A system that supports human interaction over a network

• A service that is only accessible within a local network

Which of the following is NOT a characteristic of a web service?

• Interoperability

• Human-to-machine interaction

• Application-to-application interaction

• Network communication

What does interoperability in web services mean?

• Applications can only communicate if they are on the same server

• Applications can only communicate within the same network

• Applications can communicate regardless of their underlying technology

• Applications can only communicate if they are built with the same technology

Why is network communication important for web services?

• It allows applications to communicate only within a local system

• It enables applications to communicate over the internet or different systems

• It restricts communication to secure networks

• It ensures faster data transfer within a single system
