How does GraphQL differ from REST in terms of data fetching?

GraphQL requires multiple round trips to fetch related data, while REST can fetch it in one request.

GraphQL is a database query language, while REST is a web API style.

GraphQL uses HTTP methods to define operations, while REST uses a single endpoint with query strings.

GraphQL allows the client to specify exactly what data it needs, while REST typically returns fixed resource representations.

A web developer is debugging a form submission on a website. The form data is sent to the server, and the server responds with a new HTML page. The developer notices that the URL in the browser changes to reflect the new page. Which combination of technologies and standards is primarily responsible for this behavior?

HTML for the form, HTTP for the request/response, and the browser's navigation to the new URL.

CSS for styling the form and JavaScript for client-side validation.

WebAssembly for form processing and HTTPS for secure transmission.

JavaScript's fetch() API and the browser's history API.

Which characteristic is typical of a relational database?

Data is stored in a hierarchical tree structure.

Data is stored in flexible, schema-less documents.

Data is stored as key-value pairs for fast lookups.

Data is organized into tables with rows and columns, and relationships are defined between tables.
