QCM : Internet Fundamentals and Web Development — 16 questions

Questions et réponses du QCM

1. Which statement best describes the Internet?

A browser application used to view web pages
A single website that stores all online content
A service that maps names to IP addresses
A global system of interconnected devices that transmit and receive information

A global system of interconnected devices that transmit and receive information

Explication

The Internet is a global network of interconnected devices that communicate by sending and receiving information. The other options describe a website, a browser, or DNS instead of the Internet.

2. Who is credited as the father of the Internet in the lesson?

J.C.R. Licklider
Tim Berners-Lee
Marc Andreessen
Vint Cerf

J.C.R. Licklider

Explication

J.C.R. Licklider is explicitly credited as the father of the Internet. The other names are associated with other Internet or web developments, but not this attribution.

3. What is a server in the Internet architecture described here?

A computer connected to the Internet that stores and provides web pages
A file format used to display web content
A private network used only for local devices
A program that translates domain names into IP addresses

A computer connected to the Internet that stores and provides web pages

Explication

A server stores and provides web pages over the Internet. DNS translates names, while a browser displays content.

4. What is a website?

A collection of web pages
A single IP address for a device
A protocol for transferring files
A browser used to access online content

A collection of web pages

Explication

A website is defined as a collection of web pages. An IP address, browser, and protocol are different concepts.

5. What is an IP address?

A unique identifier assigned to devices connected to the Internet
A name used to replace a server's web pages
A service that maps names to numbers
A type of browser address bar setting

A unique identifier assigned to devices connected to the Internet

Explication

An IP address uniquely identifies a device on the Internet. DNS is the service that maps names to IP addresses, not the IP address itself.

6. Which description matches IPv4?

A domain name ending in .com
An IP format made of four numbers separated by periods
A wireless standard for connecting devices
A file path inside a URL

An IP format made of four numbers separated by periods

Explication

IPv4 is the form of IP address written as four numbers separated by periods, with each number ranging from 0 to 255. The other choices describe different concepts.

7. What does Domain Name Service (DNS) do?

Maps domain names to IP addresses
Stores website files on a server
Displays web pages in a browser
Splits data into packets for transmission

Maps domain names to IP addresses

Explication

DNS maps human-readable domain names to IP addresses. Packet switching, browser display, and file storage are unrelated functions.

8. What does the country code in the domain extension .edu.sg indicate?

Educational use
Singapore
Commercial use
Network resources

Singapore

Explication

In .edu.sg, sg is the country code for Singapore. The .edu part indicates an educational institution.

9. What happens in packet switching at the source?

Domain names are converted into IP addresses
Web pages are stored on the server's hard drive
Received packets are combined into a website
Information is divided into smaller bits before transmission

Information is divided into smaller bits before transmission

Explication

Packet switching breaks information into smaller packets at the source before sending them across the network. Reassembly happens later at the destination.

10. What happens at the destination in packet switching?

Packets are put back together to form the complete information
The source divides the data into new packets again
The browser creates the web page from scratch
The message is converted into a domain name

Packets are put back together to form the complete information

Explication

At the destination, the received packets are reassembled into the original complete information. The source is where the data is split, not where it is rebuilt.

11. What is the main role of a web browser when a user accesses the World Wide Web?

It breaks data into packets for transmission
It maps domain names to IP addresses
It interprets and displays web information to the user
It stores web pages on a server’s hard drive

It interprets and displays web information to the user

Explication

Web browsers are the software applications used to access and view web information. Storing pages is the server’s job, while mapping names to IP addresses is DNS.

12. Which statement best describes the World Wide Web?

It is a method for dividing data into packets at the source
It is a service that assigns IP addresses to computers
It is a service that uses the Internet and HTTP to publish and share information
It is the physical network infrastructure that connects devices globally

It is a service that uses the Internet and HTTP to publish and share information

Explication

The World Wide Web is described as a service built on the Internet that uses HTTP to publish and share information. The other choices describe the Internet, IP addressing, or packet switching instead.

13. What is a Uniform Resource Locator used for?

It identifies a device on the Internet with a numeric code
It defines the rules for breaking data into packets
It gives the address of a file or resource on the World Wide Web
It translates domain names into IP addresses

It gives the address of a file or resource on the World Wide Web

Explication

A URL is the address of a file or resource accessible on the World Wide Web. DNS handles name-to-IP translation, not URLs.

14. Which parts are included in a URL as described here?

Protocol name, IP address, and network speed
File size, encryption key, and destination port
Protocol name, domain name, and an optional directory or file location
Domain extension, browser name, and server password

Protocol name, domain name, and an optional directory or file location

Explication

A URL contains the protocol name, the domain name, and optionally a directory or file location. The other options mix in unrelated networking details.

15. What is the first step in setting up a website?

Upload HTML before choosing a domain name
Register a DNS packet route
Get a web server connected to the Internet
Buy a browser license for visitors

Get a web server connected to the Internet

Explication

The lesson’s first setup step is to obtain a web server connected to the Internet. The domain name and website files come after that.

16. Why is a domain name tagged to the web server’s IP address during website setup?

So the browser can convert HTTP into HTTPS automatically
So users can reach the website by entering a readable name instead of the numeric address
So the website files can be stored directly in the URL
So the server can divide web pages into packets more quickly

So users can reach the website by entering a readable name instead of the numeric address

Explication

Tagging the domain name to the server’s IP lets users access the site through a memorable name rather than typing the numeric IP. This matches the lesson’s example of linking a domain like www.nyp.edu.sg to a server IP.
