20 Internet Interview Questions and Answers

The Internet is a vast and ever-changing network of interconnected computers. It is a crucial part of our daily lives, both at work and at home. As such, employers often seek candidates who have a strong understanding of the Internet and how it works. If you are interviewing for a position that requires knowledge of the Internet, you should be prepared to answer questions about its history, structure and uses. This article discusses some of the most common questions about the Internet that you may encounter during a job interview.

Internet Interview Questions and Answers

Here are 20 commonly asked Internet interview questions and answers to prepare you for your interview:

1. What is the internet?

The internet is a global network of computers that allows for the exchange of information between devices.

2. How did the internet begin and how has it evolved over time?

The internet began as a project of the United States military in the 1960s, designed to create a network that could withstand a nuclear attack. The original network was called ARPANET, and it eventually evolved into the internet as we know it today. The internet has undergone a number of changes since its inception, including the development of the World Wide Web in the 1990s, which made it much easier for users to access information online.

3. Can you explain what an IP address is and why we need it to access certain websites?

An IP address is a unique identifier for a device that is connected to the internet. We need IP addresses to access certain websites because the website needs to know where to send the information that you are requesting.

4. Why do we use domain names instead of IP addresses to access websites?

Domain names are used instead of IP addresses because they are easier to remember. A domain name is like a human name, while an IP address is like a human’s Social Security number. It is much easier to remember someone’s name than their Social Security number, and the same is true for domain names and IP addresses.

5. Do all internet users have a public IP address?

No, not all internet users have a public IP address. Many users are behind a NAT (Network Address Translation) which will give them a private IP address that is not publicly routable.

6. What are some common types of attacks on the internet?

There are many types of attacks that can be carried out on the internet, but some of the most common include denial of service attacks, man-in-the-middle attacks, and phishing attacks. Denial of service attacks can overload a server with requests, preventing legitimate users from accessing it. Man-in-the-middle attacks can intercept communications between two parties and eavesdrop or even modify the data being exchanged. Phishing attacks can trick users into revealing sensitive information, such as passwords or credit card numbers, by masquerading as a trustworthy website or email.

7. What’s the difference between HTTP and HTTPS?

HTTP is the protocol used to transfer data between a web server and a web browser. HTTPS is a secure version of HTTP that uses SSL/TLS to encrypt data before it is sent. This makes it more difficult for third parties to intercept and read the data.

8. Is there a limit to the number of devices that can be connected to the Internet at any given time? If yes, then what is it?

There is no limit to the number of devices that can be connected to the Internet at any given time. The number of devices that can be connected is limited only by the amount of available bandwidth.

9. What is your understanding of the deep web and the dark web? Are they related?

The deep web is the part of the internet that is not indexed by search engines, and therefore is not easily accessible. The dark web is a subset of the deep web that is used for illegal or illicit activity. They are related in that the dark web is part of the deep web, but they are not the same thing.

10. In which year was the World Wide Web created? By whom?

The World Wide Web was created in 1991 by Tim Berners-Lee.

11. What do you understand about virtual private networks (VPNs)? Are they safe for everyday use?

A VPN is a private network that uses a public network (usually the Internet) to connect remote sites or users together. VPNs use “virtual” connections routed through the Internet from the business’s private network to the remote site or employee. Safety is relative; however, a VPN is generally considered to be more secure than a standard public network.

12. What does DNS stand for and what does it do?

DNS stands for Domain Name System. It is a system that allows for the translation of human-readable domain names (like www.google.com) into the IP addresses that computers use to communicate with each other (like 216.58.217.46).

13. What are some important design principles that govern how the internet operates?

There are four main design principles that govern how the internet operates:

1. End-to-end principle: This principle states that the end users should be able to communicate with each other directly, without having to go through intermediate nodes.

2. Open design principle: This principle states that the design of the internet should be open and accessible to anyone who wants to improve it.

3. Layered design principle: This principle states that the internet should be designed in a series of layers, with each layer providing a specific set of functions.

4. Modularity design principle: This principle states that the internet should be designed in a modular way, so that new components can be added or removed as needed.

14. What do you think about privacy and security issues on the internet?

I think that privacy and security issues on the internet are extremely important. I think that people should be very careful about what they share online, and they should be aware of the potential risks of sharing too much information. I also think that people should be aware of the potential for companies and other organizations to collect data about them online.

15. What are some examples of real-world applications of the internet?

The internet is used for a variety of things in the real world. Some examples include online shopping, online banking, social media, and online research.

16. What are some things you don’t like about the Internet?

I don’t like that there is so much information available that it can be overwhelming. I also don’t like that there are a lot of scams and false information circulating.

17. What would happen if someone hacked into your computer while you were accessing the Internet?

If someone hacked into your computer while you were accessing the Internet, they could potentially gain access to all of the information on your computer. They could also use your computer to launch attacks on other computers or to distribute malware.

18. Who owns the Internet?

No one owns the Internet, and it is not controlled by any one organization. The Internet is a global network of computers that are interconnected and can communicate with each other.

19. What are some advantages of using the Internet?

The Internet provides a number of advantages, including the ability to connect with people around the world, access to a wealth of information, and the ability to conduct business online.

20. Can you give me some examples of services provided by the Internet?

The Internet provides a variety of services, including email, file sharing, online gaming, and web browsing.
