Internet & Impacts of Computing Quiz

What is the purpose of a protocol in internet communication?

• To translate web pages into different languages

• To encrypt data for secure communications

• To define rules and standards for data exchange

• To manage domain name registrations and IP addresses

How do TCP and IP interact?

• IP forwards the data to the DNS server to identify which TCP to use.

• TCP hands off control to HTTP, which passes it to IP.

• TCP creates packets from the data to be sent and transfers control to IP for routing.

• IP uses the SSL in conjunction with TCP to securely send data.

How does a computer turn a human-readable domain name into an IP address?

• It asks a DNS server for the corresponding IP address

• It scans addresses until it finds the one it's looking for

• It uses a Border Gateway Protocol to get the address from a nearby computer.

• It creates an IP address for the domain, and shares it with the closest DNS.

Which characteristic of blockchain technology ensures that once data has been recorded, it cannot be altered without changing all subsequent blocks?

• Ability to update data freely

• Centralized data storage

• Immutable ledger

• Unlimited data access

How do Internet packets travel to their destination?

• Along the same path and always in the same order.

• Along the same path and potentially out of order.

• Along a variety of different paths and potentially out of order.

• Along a variety of different paths and always in the same order.

Parallel computing involves the simultaneous execution of multiple tasks or processes. What benefit does this provide for data processing?

• Increased latency

• Improved speed and performance

• Reduced computational power

• Reduced data storage capabilities

Why is the Internet considered redundant?

• There are unnecessary paths in the Internet.

• If a path is down, packets can be routed a different way.

• There is a delay between when a DNS request is made and when the DNS request is received.

• If a part of the Internet goes down, there is a backup system that can be brought online.

The figure below represents a network of physically linked computers labeled A through F. A line between two computers indicates that the computers can communicate directly with each other. Any information sent between two computers that are not directly connected must go through at least one other computer. For example, information can be sent directly between computers B and D, but information sent between B and E must go through other computers.

What is the minimum number of connections that must be broken or removed in the network before computer A can no longer communicate with computer F?

• 1

• 2

• 3

• 4

Which of the following is a contributing factor to the digital divide?

• Increasing government regulation of the internet.

• Equal distribution of digital resources.

• Socioeconomic inequalities in access to technology.

• Universal access to high-speed internet.

How do the World Wide Web and the Internet work together?

• The World Wide Web is an alternative name for the Internet.

• The World Wide Web is a subset of the Internet, primarily focusing on websites.

• The Internet is a software application used for browsing the World Wide Web.

• The Internet is a subset of the World Wide Web, primarily focusing on securing connections.
