1. HTML5 introduced the <canvas> element for drawing graphics via scripting.

True

False

HTML5 introduced the <canvas> element, which allows for drawing graphics via JavaScript. This element provides a resolution-dependent bitmap canvas that can be used for rendering graphs, game graphics, or other visual images. It supports dynamic, scriptable rendering of 2D shapes and bitmap images, making it a powerful tool for web developers to create complex graphics without relying on external plugins.

2. What are the currently used languages for making webpages?

HTML

CSS

XML

XHTML

All of the above

HTML (HyperText Markup Language) and CSS (Cascading Style Sheets) are the primary languages used for creating and styling webpages. XML (eXtensible Markup Language) and XHTML (eXtensible HyperText Markup Language) are also used in web development. HTML provides the structure of the webpage, CSS is used for layout and design, XML is often used for data storage and transport, and XHTML is a stricter version of HTML that follows XML syntax rules. All these languages play important roles in various aspects of web development.

3. A website can be made up of one webpage.

True

False

A website can indeed be made up of just one webpage. While many websites consist of multiple interconnected pages, there are instances where a single webpage serves the entire purpose of the site. This is often the case with simple sites like online portfolios, single-product promotions, or landing pages. Despite being a single page, it can still include various elements like text, images, videos, and links to provide a complete user experience.

4. How does the web browser differentiate code from normal English words?

By italicizing it

By the font you type it in

By putting it in "double quotation" marks

By putting the information in < tag > marks

A web browser differentiates code from normal English words by recognizing information within < tag > marks, which are HTML tags. These tags tell the browser how to interpret and display the content. For example, <p> marks the beginning of a paragraph, while </p> marks the end. HTML tags define the structure and format of the webpage, allowing the browser to render it correctly. Tags are a fundamental part of HTML and are essential for creating structured web content.

5. CSS Grid Layout is a one-dimensional layout method for the web.

True

False

CSS Grid Layout is a two-dimensional layout method for the web, allowing for both rows and columns. Unlike CSS Flexbox, which is primarily one-dimensional (focusing on either row or column layout), CSS Grid can handle complex layouts involving both dimensions, providing more control and flexibility in designing web page structures.

6. Service workers can intercept and handle network requests, enabling offline capabilities for web applications.

True

False

Service workers are a type of web worker that intercepts and handles network requests, enabling offline capabilities and other advanced features for web applications. They run in the background, separate from the web page, allowing for caching of resources and background synchronization. This enables web applications to function offline or with unreliable network connections by serving cached content.

7. HTTP/2 significantly reduces the latency by allowing multiple simultaneous requests over a single TCP connection.

True

False

HTTP/2 significantly reduces latency by allowing multiple simultaneous requests over a single TCP connection. This is achieved through multiplexing, where multiple streams of data are sent concurrently over a single connection, unlike HTTP/1.1, which requires a separate connection for each request/response pair. HTTP/2 also includes features like header compression and server push, further improving performance and efficiency.

8. Can you make "white space" appear on a browser? How?

Yes, by using special HTML tags.

No, the browser ignores all white space.

Yes, the browser displays everything exactly as you type it.

Yes, depending on the which program you type it up in.

Yes, you can make "white space" appear on a browser by using special HTML tags. Normally, browsers collapse multiple spaces and line breaks into a single space. To preserve white space, you can use the <pre> tag, which maintains the formatting exactly as it is typed, or use CSS properties like white-space: pre to achieve the same effect. These methods ensure that white spaces are displayed as intended on the webpage.

9. WebAssembly is a low-level language that runs alongside JavaScript in modern web browsers.

True

False

WebAssembly is a low-level, binary instruction format designed for efficient execution and compact representation. It runs alongside JavaScript in modern web browsers, allowing code written in multiple languages (like C, C++, and Rust) to run at near-native speed. WebAssembly enhances performance for computationally intensive tasks, complementing JavaScript in web applications.

10. Progressive Web Apps (PWAs) require a constant internet connection to function.

True

False

Progressive Web Apps (PWAs) do not require a constant internet connection to function. They are designed to work offline or with unreliable network connections by leveraging technologies like service workers for caching resources and enabling background processes. PWAs provide a native app-like experience with features like offline access, push notifications, and fast loading times, even in low or no connectivity scenarios.
