1⃣ Front: What is the Internet?

A global network of interconnected computer networks that communicate using shared protocols.

2⃣ Front: What is a computer network?

Back: A group of computing devices connected together so they can communicate and share data.

3⃣ Front: What is the difference between the Internet and the World Wide Web?

Back: The Internet is the network itself; the World Wide Web is a collection of websites that run on the Internet.

4⃣ Front: What is a router?

Back: A device that directs data packets between different networks to help them reach their destination.

5⃣ Front: What is an ISP?

Back: An Internet Service Provider — a company that provides access to the Internet

6⃣ Front: What is bandwidth?

Back: The maximum amount of data that can be transmitted per second over a network.

7⃣ Front: What is a protocol?

Back: A set of rules that define how data is sent and received over a network.

8⃣ Front: What is packet switching?

Back: Breaking data into small packets that travel independently across the network and are reassembled at the destination.

9⃣ Front: What is an IP address?

Back: A unique numerical identifier assigned to a device on a network.

🔟 Front: Why is the Internet fault-tolerant?

Back: If one path fails, packets can take alternate routes to reach their destination

What is the Internet?

A global system of interconnected computer networks that use standardized protocols to communicate.

What is the World Wide Web?

A collection of linked documents and resources accessed over the Internet using HTTP.

What is a computer network?,A group of computing devices connected to share data and resources.

What is a computing system?

A collection of devices and software working together for a common purpose.

What is a computing device?

A physical machine capable of running programs.

What is a client-server model?

A network model where clients request services and servers provide them.

What is peer-to-peer networking?

A network model where devices share resources directly without a central server.

What is a router?

A device that forwards data packets between networks.

What is routing?

The process of selecting paths for data to travel across a network.

What is redundancy in networks?

Having multiple possible paths so data can reroute if one path fails.

What does fault-tolerant mean?

The system continues to function even when parts fail.

What is bandwidth?

The maximum amount of data that can be sent per second.

What is latency?

The time it takes for data to travel from sender to receiver.

What is a packet?

A small chunk of data sent over a network.

What is packet switching?

Sending data as packets that may take different paths and are reassembled.

Why does the Internet use packet switching?

It increases efficiency and allows rerouting if paths fail.

What is packet loss?

When packets fail to reach their destination.

What causes packet loss?

Network congestion, hardware failure, or interference.

What is a protocol?

A set of rules that define how data is formatted, sent, and received.

Why are protocols necessary?

They allow different devices and networks to communicate reliably.

What is IP?

A protocol that handles addressing and routing packets.

What is TCP?

A protocol that ensures reliable, ordered delivery of data.

What does TCP guarantee?

Packets arrive correctly, in order, and without duplicates.

What does IP not guarantee?

Delivery, order, or correctness of packets.

What is HTTP?,A protocol used to transfer web pages.

What is HTTPS?

HTTP with encryption for secure communication.

What is encryption?

The process of encoding data to protect it from unauthorized access.

What is DNS?

A system that translates domain names into IP addresses.

Why is DNS needed?

Humans remember names better than numbers.

What is an IP address?

A unique numerical identifier for a device on a network.

How do routers know where to send packets?

They use routing tables and IP addresses.

Why can packets take different paths?

To avoid congestion or failed routes.

What is scalability?

The ability of a network to grow without major redesign.

What tradeoff exists between speed and reliability?

More reliability often increases delay.

What tradeoff exists between security and convenience?

More security can make access slower or harder.
