Web Technology MCQ: Quiz!

DNS (Domain Name System) is an Internet service that translates domain names to IP addresses. When a user enters a domain name in their web browser, the DNS server is responsible for converting that domain name into the corresponding IP address of the server hosting the website. This IP address is then used to establish a connection and retrieve the requested web page. Therefore, the correct answer is IP address.

FTP (File Transfer Protocol) is the correct answer because it is specifically designed to transfer files between computers over a network. FTP allows users to upload, download, and manage files on a remote server. It provides a reliable and efficient method for transferring files, making it a commonly used protocol for file sharing and remote file management. HTTP (Hypertext Transfer Protocol) is primarily used for transferring web pages and data, UDP (User Datagram Protocol) is a connectionless protocol used for fast transmission of data, and FTTP (Fiber to the Premises) is a broadband network architecture.

All of the given statements are true. HTTP (Hypertext Transfer Protocol) runs over TCP (Transmission Control Protocol), which provides reliable communication between the client and the server. HTTP allows information to be stored in a URL (Uniform Resource Locator) through query parameters or path segments. Additionally, HTTP can be used to test the validity of a hypertext link by sending a request to the link and checking the response status code.

A URL stands for Uniform Resource Locator. It is a standardized way to address and locate resources on the internet. It consists of various components such as the protocol (http, https, ftp), the domain name (www.example.com), and the specific path to the resource. The term "uniform" implies that the format and structure of the URL are consistent and universally recognized. The term "resource" refers to any digital content, such as web pages, images, or files, that can be accessed through the internet. Therefore, the correct answer is uniform resource locator.

A static website is the simplest form of a website where the content is delivered without the use of server-side processing. This means that the web pages are pre-designed and do not change based on user interactions or inputs. Static websites are mainly used to provide information or showcase products/services without any complex functionality. Unlike dynamic websites that use server-side processing to generate content on the fly, static websites are easier to develop and maintain as they do not require any server-side scripting or database integration.

A dynamic web page is a web page that is generated on demand by a program or a request from a browser. Unlike static web pages, which remain the same every time they are displayed, dynamic web pages can change and adapt based on various factors such as user input, database queries, or real-time data. This allows for more interactive and personalized web experiences.

A computer that stores different web pages is called a web server. A web server is responsible for hosting websites and delivering web pages to users when they request them. It receives requests from web browsers, retrieves the requested web pages from its storage, and sends them back to the user's browser for display. This is how websites are made accessible to users over the internet.

HTTPS (Hypertext Transfer Protocol Secure) is the correct answer because it is a protocol that provides secure communication over the internet. It combines the HTTP protocol with SSL/TLS encryption to ensure that data transmitted between a web server and a browser remains secure and cannot be easily intercepted or tampered with by unauthorized individuals. This is particularly important for sensitive information such as passwords, credit card details, and personal data.

A web browser is a program that can display a web page and is also used to view HTML documents. It is capable of interpreting and rendering HTML, CSS, and JavaScript code to visually present web pages to users. Therefore, the correct answer is "Both" because a web browser can perform both functions.

The GET method is used to request data from a specified source. It is commonly used to retrieve information from a server or a website. Unlike the POST method which is used to send data to the server, the GET method is used for retrieving data. This can include retrieving web pages, images, documents, or any other type of data that is available on the specified source.

The Common Gateway Interface (CGI) is a standard protocol that allows web servers to interact with executable files on a web server. This means that CGI is used to generate executable files from web content by the web server. CGI scripts can be written in various programming languages such as Perl, Python, or C++, and they are used to process user input, generate dynamic web content, and perform other server-side tasks.

Both statements are true. HTTP (Hypertext Transfer Protocol) runs over TCP (Transmission Control Protocol), which is a reliable transport protocol. This means that HTTP uses TCP to establish a connection, ensure data integrity, and provide reliable delivery of information. Additionally, HTTP allows information to be stored in a URL (Uniform Resource Locator). This is commonly seen in query strings, where data is appended to the end of a URL to pass parameters or additional information to a web server.

The values GET, POST, HEAD, etc are specified in the request line of an HTTP message. The request line contains the method (GET, POST, etc) that the client wants to use for the request. This line is the first line of the request and it specifies the type of request being made to the server.

Both web browsing and email are examples of client-server applications. In web browsing, the user's web browser acts as the client, sending requests to web servers and receiving responses. In email, the user's email client (such as Outlook or Gmail) acts as the client, connecting to an email server to send and receive messages. In both cases, there is a client (user's device) that interacts with a server (web server or email server) to access and exchange data.

A web cookie is a small piece of data that is sent from a website and stored in the user's web browser while the user is browsing the website. This allows the website to remember information about the user, such as their preferences or login information, and provide a personalized browsing experience.

The World Wide Web Consortium (W3C) is the central organization in charge of creating and maintaining web standards. The W3C has enacted a slew of standards, including the standard markup languages that we use to create websites. They develop standards and guidelines to help everyone build a web based on the principles of accessibility, internationalization, privacy, and security. 

When designing an HTML form to purchase furniture, it is preferable to send the data to the server using either the GET or POST method. Both methods can be used to send data securely, and the choice between them depends on the specific requirements of the form. The GET method appends the form data to the URL, making it visible in the browser's address bar and potentially bookmarkable. On the other hand, the POST method sends the form data in the body of the HTTP request, making it more secure and suitable for sensitive information like payment details. Therefore, either of GET or POST can be used based on the specific needs of the form.
