Client-side programming is used for tasks like user interface design and validation, while server-side programming is used for tasks like database operations and business logic.
2. What is responsive web design, and why is it important?
Responsive web design is an approach to web design that ensures a website looks good and functions correctly on a variety of devices and screen sizes. This is important because more and more people are accessing the internet on devices other than desktop computers, such as smartphones and tablets. A responsive website adapts to the user’s device and provides a better user experience.
3. Can you explain the difference between cookies, local storage, and session storage?
Cookies are small pieces of data stored on a user’s device by a website. They are sent to the server with each request and are used for tasks like user authentication and tracking user behavior. Local storage and session storage are newer technologies that allow developers to store data on the user’s device without sending it to the server. Local storage persists even after the user closes the browser, while session storage is cleared when the browser is closed.
4. What is the difference between HTTP and HTTPS?
HTTP (Hypertext Transfer Protocol) is the protocol used for transmitting data over the internet. HTTPS (Hypertext Transfer Protocol Secure) is a secure version of HTTP that encrypts the data transmitted between the server and the user’s device. HTTPS is important for ensuring the security and privacy of sensitive information, such as credit card numbers and passwords.
5. Can you explain the concept of a RESTful API?
A RESTful API is a type of web API that follows the principles of Representational State Transfer (REST). This means that the API is designed to be stateless, with each request containing all the information necessary for the server to process it. RESTful APIs use standard HTTP methods (such as GET, POST, PUT, and DELETE) to perform operations on resources, and they typically return data in a standardized format such as JSON or XML.
