Understanding Internet Infrastructure and Protocols

What is the role of the Domain Name System (DNS) in the internet?

• It assigns unique IP addresses to devices.

• It translates domain names into IP addresses.

• It ensures reliable data transmission.

• It determines the best path for a packet.

Which protocol is responsible for communication between web browsers and servers?

• IP

• DNS

• HTTP

• TCP

What does the term "bandwidth" refer to in a computing network?

• The physical distance between two routers.

• The amount of data that can be transmitted in a fixed amount of time.

• The number of devices connected to a network.

• The speed at which a packet travels through the network.

How does a router determine the best path for a packet to reach its destination?

• By using the shortest physical distance.

• By checking the IP address of the destination.

• By using routing protocols to evaluate multiple paths.

• By translating domain names into IP addresses.

What is the primary function of the Internet Protocol (IP)?

• To ensure data is transmitted reliably.

• To assign unique addresses to devices.

• To translate domain names into IP addresses.

• To determine the best path for data packets.

Which of the following best describes a "fault-tolerant" system?

• A system that never fails.

• A system that can continue to operate even if a component fails.

• A system that requires manual intervention to recover from failures.

• A system that is immune to cyber attacks.

What is the purpose of redundancy in a computing network?

• To increase the speed of data transmission.

• To provide backup paths in case of failure.

• To reduce the number of devices needed.

• To simplify network design.

Which protocol ensures reliable data transmission over the internet?

• HTTP

• DNS

• TCP

• IP

What is the "digital divide"?

• The gap between those who have access to modern information and communication technology and those who do not.

• The difference in internet speeds between urban and rural areas.

• The separation of digital data into packets.

• The division of a network into subnets.

What is the World Wide Web?

• A protocol for data transmission.

• A system of interlinked hypertext documents accessed via the internet.

• A physical network of cables and routers.

• A type of computing device.
