Y8 Network Homework 1

How does data typically travel on the internet?

• Through direct, dedicated connections between devices.

• By establishing a single, fixed path for all data.

• In a much less direct fashion, using multiple paths.

• Only when all wires and computers are working perfectly.

How is digital information prepared for transmission over the internet?

• Information is broken down into smaller pieces called packets for transport.

• A space shuttle is used to transport large amounts of data.

• Digital information can only be sent if it fits into a single large file.

• Each piece of information travels on a dedicated truck.

Are you enjoying the video lesson?

• Yes

• No

What is the primary role of routers on the internet?

• They always choose the most direct path to ensure fastest delivery.

• They are responsible for driving the packets to their destination.

• They only send packets if the entire network path is clear and uncongested.

• They act as traffic managers, choosing the 'cheapest' available path for each piece of data.

What is the function of the Transmission Control Protocol (TCP) in data delivery?

• It ensures that data is always sent through the most direct route.

• It manages the sending and receiving of data packets, ensuring all are delivered and reassembled correctly.

• It is responsible for breaking down large files into smaller packets.

• It determines the 'cheapest' path for data based on politics and relationships between companies.

What key principles contribute to the internet's reliability and scalability?

• Fault tolerance and redundancy, allowing the network to continue functioning even if parts fail.

• The use of direct, dedicated connections for every device on the network.

• A centralized control system that manages all data traffic.

• The ability to only connect a limited number of devices to maintain stability.
