Internet and Packets

What is the responsibility of Lynn Root at Spotify?

• Software engineer

• Network administrator

• Data analyst

• Web developer

How does data travel on the internet?

• Through direct, dedicated connections

• By following a fixed path

• In a packet of information

• By using multiple routers

Who were the designers of the internet's protocols and architecture?

• Lynn Root and Bob Khan

• Spotify engineers

• Early internet users

• Unknown individuals

What are routers in the context of the internet?

• Special computers that manage packet movement

• Devices that connect physically to the internet

• Computing devices that help packets reach their destination

• Systems that work together due to agreed-upon standards

How does TCP ensure reliable data delivery?

• By sending packets through direct connections

• By choosing the most direct route for data

• By breaking data into packets and verifying delivery

• By using redundant routers for fault tolerance

What happens if some packets are missing during data transfer?

• The data is lost and cannot be recovered

• The data is sent again until all packets are received

• The data is delivered as is, even if incomplete

• The data is reassembled from other packets

Why is the internet considered fault tolerant?

• Because it uses direct connections for data transfer

• Because it can handle traffic congestion and road conditions

• Because it has multiple paths for sending packets

• Because it can scale to billions of devices

What are the agreed-upon standards for data transfer on the internet called?

• Internet protocols

• Routing algorithms

• Packet inventories

• Network architectures

How do computing devices or routers help packets reach their destination?

• By physically connecting to each other

• By communicating with each other

• By working together based on agreed-upon standards

• By reassembling packets at the destination

What is the main purpose of TCP in data transfer?

• To break data into packets

• To choose the cheapest available path for data

• To manage the sending and receiving of packets

• To ensure the reliability of the internet
