Online search engines like Google, Bing, and DuckDuckGo help to make information readily available to us when we need it. However, what do Wikis do that these search engines do not that also makes them useful in their own sense?

• They prioritize results based on the relative connectedness of web pages

• They are guaranteed to be written by experts.

• They help consolidate and organize information into a nice online reference

• They can index results so that you can sort through them to get to a desired result.

Which of the following is an advantage of using standard protocols for internet communication?

• Any user can adapt the standard protocols to allow them to send data over the internet using their own unique protocols

• Devices of different types by different manufacturers can communicate directly over the internet.

• Technology manufacturers can sell additional hardware to allow devices using different internet protocols to communicate

• The types of data which can be transmitted is limited to certain formats (e.g. images, text, video)

Which of the following is NOT a benefit of cloud computing?

• Data can be backed up offsite to protect against local emergencies or disasters.

• Users can access data from any remote location or setting that has online access.

• Multiple users can collaboratively interact with shared data.

• Cloud data cannot be subpoenaed by law enforcement.

Which of the following best describes the function of the Domain Name System (DNS)?

• DNS provides a directory service that associates a domain name with the IP addresses of the server hosting the domain.

• DNS is a service that individuals or corporations can use to purchase and register ownership of domain names

• The domain name system is a non-profit organization that regulates the introduction and assignment of new, top-level domains (TLD).

• DNS determines the most efficient route through a network that a document should follow as it is transmitted from one node to the next.

Which of the following statements describe positive impacts that the Internet and World Wide Web have made on global society?

I.Online educational opportunities have increased substantially year after year, which is giving more people the chance to pursue higher education II.The ability of private persons to sell items online has created a new form of commerce that has never been seen before III.Peer-to-peer networks have ensured that creators are paid fairly for digital content they have created and released on the internet IV.Video streaming sites have allowed both commercial and independent movie producers to get their films seen by more viewers at lower distribution costs

• II, IV

• I, II, IV

• I, III, IV

• All of the above

Which of the following is a reason for systems to adopt a new internet protocol standard (IPv6) instead of the original standard (IPv4)?

• IPv6 allows data to be transferred at much higher speeds than with IPv4

• IPv6 allows a much larger range of addresses than IPv4.

• IPv6 enables encrypted communication, whereas IPv4 does not

• IPv6 offers lossless compression of data, whereas IPv4 uses lossy compression Algorithms.

Andre and Gaby are sending each other messages via the internet and use Andre’s public key to encrypt each message. No other encryption is used. What is the most likely scenario?

• Andre will be the only person who has access to the message and can read it.

• Andre is certain that Gaby is the sender of the message

• A person trying to gain access to Andre’s message can easily read his message

• Andre can reply to Gaby and she will be able to read his message

The DNS system is designed to be very scalable and allows for top level domains to be broken down into subdomains and those subsequently broken down into further subdomains. You have taken ownership of the widets.org domain and you wish to create additional subdomains within widgets.org. Which of the following are valid subdomains within widgets.org?

• widgets.org/north

• uppereast.widgets.org

• widgets.org.northwest

• newyork.widgets.org

Which of the following features of the internet is instrumental in ensuring that different types of data can be shared by a diverse range of different devices and users?

• The use of open standard protocols for sending data.

• The ability of providers to throttle traffic to certain servers.

• The outlawing of the use of IPv4 for traffic routing.

• The hierarchical nature of the Domain Name System.
