This Web 2.0 MCQ quiz helps you practice interactive web concepts - AJAX, APIs, and social features - so you can check gaps and build confidence. Get instant feedback after each question and finish in minutes. For more practice, try the broader internet trivia or focus on data exchange with our API quiz .
Which of the following best describes a Web 2.0 application?
A static website with fixed content
A Flash?based multimedia presentation
A server?rendered page without client?side scripting
A dynamic, user?driven site emphasizing social interaction
Web 2.0 applications are characterized by dynamic content, user participation, and social networking features. They often use client-side scripting and AJAX to provide interactive experiences. Static sites lack these interactive and participatory qualities. Learn more about the evolution of Web 2.0 on Wikipedia.
What does AJAX stand for?
Advanced Java Application eXchange
Automatic JSON and XHTML
Asynchronous JScript and XHTML
Asynchronous JavaScript and XML
AJAX is an acronym for Asynchronous JavaScript and XML, a technique that allows web pages to update asynchronously by exchanging data with servers behind the scenes. Though JSON is commonly used today, XML was originally prominent. See the AJAX overview at MDN.
Which technology is primarily used to interact programmatically with a remote web service?
SVG
HTML
API
CSS
An API (Application Programming Interface) defines methods and data formats for interacting with remote services. Web 2.0 apps rely heavily on RESTful or SOAP APIs to fetch and manipulate data. HTML and CSS are presentation languages, not interfaces to back-end services. For more, see this API primer.
Which of these is an example of user?generated content in Web 2.0?
Compiled CSS stylesheets
Server log files
Static HTML template
User comments on a blog
User-generated content is any content created by users, such as comments, reviews, or posts. Blog comments are a classic Web 2.0 feature, fostering interactivity and community. Static templates and server logs are not created by users. Visit this article on UGC for more details.

<li><strong>AJAX Fundamentals</strong> - <p>Asynchronous JavaScript and XML (AJAX) empowers web pages to fetch and display data without full reloads, significantly improving user experience (MDN Web Docs). For example, using fetch('api/items').then(res⇒res.json()) updates the DOM on the fly. Mnemonic tip: "AJAX = Asking Just A XHR" to recall its reliance on XMLHttpRequest.</p> </li>
<li><strong>RESTful API Principles</strong> - <p>REST (Representational State Transfer) uses standard HTTP methods - GET, POST, PUT, DELETE - to interact with resources, making services scalable and stateless (Roy Fielding's dissertation, 2000). A typical endpoint like GET /users/123 returns user data in JSON, while POST /users creates new records. Remember "CRUD" (Create, Read, Update, Delete) to map actions to HTTP verbs.</p> </li>
<li><strong>User-Generated Content (UGC)</strong> - <p>UGC shifts content creation to users, driving engagement through blogs, wikis, and forums; Wikipedia and YouTube are prime examples (Pew Research Center). Platforms often implement moderation and reputation systems to maintain quality. Think "You publish, You prosper" to underscore the Web 2.0 participatory ethos.</p> </li>
<li><strong>Mashups & Interoperability</strong> - <p>Mashups combine multiple APIs or data sources - like overlaying real estate listings on Google Maps - to create new services (O'Reilly Media, 2005). This interoperability relies on open APIs and standardized formats such as JSON and JSONP. Tip: visualize "mix-and-match blocks" to remember how mashups assemble diverse endpoints.</p> </li>
<li><strong>Folksonomy & Social Tagging</strong> - <p>Folksonomy lets users apply free-form tags to organize content, enabling dynamic discovery on platforms like Flickr and del.icio.us (MIT CSAIL research). Tags form emergent classification systems that adapt to community language. Use the phrase "Tag it to tag along" to recall how tagging fosters social navigation.</p> </li>
