1. What is fault tolerance?

The ability of a system to continue working even when one or more parts fail.

2. Why is fault tolerance important?

It prevents a system from completely shutting down when something goes wrong.

3. What is redundancy?

Having extra components or backup systems in case something fails.

4. How does redundancy help fault tolerance?

If one component fails another component can take over.

5. What is a single point of failure?

A part of a system that if it fails, can cause the entire system to stop working.

6. How can a system prevent a single point of failure?

By using backup systems and multiple components.

7. What happens if a system does not have fault tolerance?

One failure could cause the entire system to stop working.

8. What is parallel computing?

Dividing a large task into smaller tasks that are completed at the same time.

9. What is distributed computing?

Using multiple computers to work together and complete a task.

10. What is the difference between parallel and distributed computing?

Parallel computing completes multiple parts of a task simultaneously

11. What is an advantage of parallel computing?

It can complete tasks faster because multiple tasks happen at the same time.

12. What is an advantage of distributed computing?

It allows multiple computers to share the workload and resources.

13. How can distributed computing improve fault tolerance?

If one computer fails other computers may continue completing the task.

14. What is a disadvantage of distributed computing?

Communication between computers can create delays or problems.

15. Why is parallel computing useful?

It makes processing large or complicated tasks more efficient.

16. What is the Internet?

A worldwide network of connected computer networks that communicate with each other.

17. What is a protocol?

A set of rules that allows devices to communicate with each other.

18. What is an IP address?

A numerical address that identifies a device on a network.

19. What is DNS?

DNS translates website domain names into IP addresses.

20. What is a packet?

A small piece of data sent across a network.

21. Why is information divided into packets?

It makes sending data across networks more efficient.

22. What is routing?

The process of finding a path for data packets to travel across a network.

23. What happens if a network pathway fails?

Data can be redirected through another available pathway.

24. Why is the Internet considered fault tolerant?

Because it has multiple pathways so data can still travel if one pathway fails.

25. What is bandwidth?

The maximum amount of data that can be transmitted in a certain amount of time.

26. What is latency?

The time it takes for data to travel from one point to another.

27. What is TCP?

A protocol that helps ensure data packets arrive correctly and in the right order.

28. What is IP responsible for?

Addressing and routing packets so they reach their destinations.

29. What is the difference between the Internet and the World Wide Web?

The Internet is the global network while the Web is a service that operates using the Internet.

30. What is HTTPS?

A secure version of HTTP that encrypts communication between a browser and a website.

31. A company has two servers. If one stops working, the other takes over. What concept is being used?

Fault tolerance and redundancy.

32. A computer divides a complicated calculation into four smaller tasks and completes them simultaneously. What is this?

Parallel computing.

33. Four different computers work together to process information. What is this?

Distributed computing.

34. Someone visits a website but the website's main network pathway stops working. The data travels through another pathway. What concept does this demonstrate?

Fault tolerance and routing.

35. A computer system has only one server. If that server fails the entire system stops working. What is this an example of?

A single point of failure.

36. A user types a website name into their browser. What translates that name into an IP address?

DNS.

37. A large file is divided into smaller pieces before being sent over the Internet. What are these pieces called?

Packets.

38. A system uses multiple computers to share a large workload. What type of computing is this?

Distributed computing.

39. A website takes a long time to respond because there is a delay in data transmission. What is this called?

Latency.

40. A network can handle more users by adding additional servers. What concept does this demonstrate?

Scalability.
