What is the primary purpose of HTML in web development?
A Managing data
B Structuring content
C Adding styles
D Creating dynamic interactions
HTML (HyperText Markup Language) is used to structure content on web pages. It provides a way to define elements such as headings, paragraphs, links, and images, forming the basic building blocks of a website.
Which language is primarily used for styling web pages?
A CSS
B PHP
C HTML
D JavaScript
CSS (Cascading Style Sheets) is used to style HTML elements. It controls the layout, colors, fonts, and positioning of elements on a webpage, enhancing the visual appearance and user experience of a website.
Which of the following is a key feature of Single Page Applications (SPAs)?
A Server side rendering
B Static page design
C Multiple page reloads
D Faster content loading
SPAs load content dynamically without reloading the entire page. This enables faster interactions by only loading the necessary content, providing a smoother and more responsive user experience compared to traditional multi page applications.
Which of the following frameworks is most commonly used for building modern web frontends?
A Flask
B Django
C Angular
D Node.js
Angular is a widely used JavaScript framework for building dynamic, single page web applications. It provides tools for creating reusable components, handling routing, and managing application state, making it ideal for large scale web applications.
What does REST stand for in the context of web development?
A Reliable Endpoint Security
B Representational State Transfer
C Rapid Server Technology
D Real Time Engineering Services
REST (Representational State Transfer) is an architectural style used in web services. It uses stateless communication and standard HTTP methods (GET, POST, PUT, DELETE) to enable interactions between clients and servers in a scalable way.
Which of the following web technologies is used for building real time web applications?
A CSS
B PHP
C React
D WebSockets
WebSockets provide full duplex communication between the client and the server, allowing for real time data exchange. This is essential for applications like live chat, stock tickers, and gaming, where instant updates are required.
Which of the following is a key feature of backend development?
A Styling web pages
B Writing HTML
C Managing databases
D Designing user interfaces
Backend development involves managing the server, database, and application logic. This includes tasks like handling database queries, processing user requests, and ensuring data security, all of which are crucial for building dynamic web applications.
Which JavaScript framework is commonly used for building user interfaces in web applications?
A React
B Flask
C Angular
D Django
React is a popular JavaScript library for building user interfaces, particularly single page applications. It allows developers to create reusable components, making it efficient for managing dynamic content and updating the UI based on user interactions.
What is the main advantage of using a framework like Vue.js for frontend development?
A Manages backend APIs
B Simplifies database management
C Allows for building dynamic UIs
D Provides server side rendering
Vue.js is a JavaScript framework used for building dynamic and interactive user interfaces. It allows developers to create reactive components, making it easier to update the user interface based on user inputs or changes in application state.
Which HTTP method is used to request data from a RESTful API?
A DELETE
B POST
C GET
D PUT
The GET method is used in RESTful APIs to request data from the server. It retrieves data without modifying it, ensuring that the data remains unchanged and is returned to the client for display or further processing.
Which of the following web technologies allows for the creation of dynamic, data driven websites?
A PHP
B CSS
C HTML
D JavaScript
PHP is a server side scripting language widely used for building dynamic, data driven websites. It interacts with databases, processes form data, and can generate dynamic content based on user requests or other criteria.
Which of the following is used for server side scripting in web development?
A HTML
B CSS
C Node.js
D React
Node.js is a JavaScript runtime environment that allows developers to write server side scripts in JavaScript. It is widely used for building fast, scalable web applications, handling server requests, and interacting with databases.
What is the primary advantage of using GraphQL for API development?
A Enhances server performance
B Reduces code complexity
C Simplifies database queries
D Fetches only the necessary data
GraphQL allows clients to request only the data they need, reducing over fetching and under fetching of data. This makes it more efficient than traditional RESTful APIs, where fixed endpoints often return excessive data.
Which of the following is an example of a backend programming language used in web development?
A CSS
B PHP
C HTML
D JavaScript
PHP is a widely used server side programming language that is ideal for building dynamic web applications. It processes backend logic, interacts with databases, and generates dynamic content that is sent to the client.
Which of the following best describes the purpose of responsive web design?
A Make websites mobile friendly
B Enhance SEO
C Optimize database queries
D Improve server performance
Responsive web design ensures that websites adapt to various screen sizes and devices. It uses flexible grid layouts and media queries to provide an optimal viewing experience across desktops, tablets, and smartphones, improving accessibility and user experience.
