: 2: Moderate AACSB: Information Technology LO: 7.3: How do the Internet and Internet technology work and how do they support communication and e-business? 79) Describe and explain the idea of "net neutrality." Are you in favor of net neutrality? Why or why not?
: Network neutrality describes the current equal access by users to Internet bandwidth, regardless of the services they are using on the Internet. Network neutrality is the idea that Internet service providers must allow customers equal access to content and applications, regardless of the source or nature of the content. Presently, the Internet is indeed neutral: all Internet traffic is treated equally on a first-come, first-served basis by Internet backbone owners. The Internet is neutral because it was built on phone lines, which are subject to "common carriage" laws. These laws require phone companies to treat all calls and customers equally. For example, someone using the Internet to download large movie files pays the same rate as someone accessing their email. Now telecommunications and cable companies want to be able to charge differentiated prices based on the amount of bandwidth consumed by content being delivered over the Internet. Student opinions will vary; one might be: I support network neutrality because the risk of censorship increases when network operators can selectively block or slow access to certain content.
: 1: Easy AACSB: Information Technology LO: 7.1: What are the principal components of telecommunications networks and key networking technologies? 26) How does packet switching work?
: Packet switching is a method of slicing digital messages into parcels called packets, sending the packets along different communication paths as they become available, and then reassembling the packets once they arrive at their destinations. Packet switching makes much more efficient use of the communications capacity of a network than did circuit-switching. In packet-switched networks, messages are first broken down into small fixed bundles of data called packets. The packets include information for directing the packet to the right address and for checking transmission errors along with the data. The packets are transmitted over various communications channels using routers, each packet traveling independently. Packets of data originating at one source will be routed through many different paths and networks before being reassembled into the original message when they reach their destinations.

The firm hires many freelancers who come into the office on an ad hoc basis and it does not have a lot of money to spend on infrastructure. What type of network will you recommend?
: Student answers will vary. An example answer is: I would recommend a mixed Ethernet and wireless network. The Ethernet LAN would connect the web servers and primary workstations and connect via cable service to the Internet. Freelancers could connect wirelessly via access points.

: The application layer enables client application programs to access the other layers and defines the protocols that applications use to exchange data. One of these application protocols is the Hypertext Transfer Protocol (HTTP), which is used to transfer web page files. The transport layer is responsible for providing the application layer with communication and packet services. This layer includes TCP and other protocols. The Internet layer is responsible for addressing, routing, and packaging data packets called IP datagrams. The Internet Protocol is one of the protocols used in this layer. At the bottom of the reference model, the network interface layer is responsible for placing packets on and receiving them from the network medium, which could be any networking technology. Data sent from one computer to the other passes downward through all four layers, starting with the sending computer's application layer and passing through the network interface layer. After the data reach the recipient host computer, they travel up the layers and are reassembled into a format the receiving computer can use. If the receiving computer finds a damaged packet, it asks the sending computer to retransmit it. This process is reversed when the receiving computer responds.

: The two ways to communicate a message in a network are analog signals and digital signals. An analog signal is represented by a continuous waveform that passes through a communications medium and is used for voice communication. Examples include the telephone handset and other types of speakers that generate analog sound. On the other hand, digital signals are binary waveforms (not continuous) that communicate information as strings of two discrete states: one bit or zero bits (often depicted as strings of zeroes and ones). Computers use these types of signals and use modems to convert digital signals to analog signals.

: Web 3.0 is the vision of the next generation of the web in which all of the information available on the web is woven together into a single meaningful experience, such that the 500 billion web pages become more productive for the ordinary user. Sometimes referred to as the "Semantic Web," it is an effort to add a layer of meaning to existing information to reduce the amount of human time spent in searching and processing that information. Student views on the impact on businesses would vary. An example answer is: This potentially could have huge effects on businesses as simple analysis becomes mechanized, requiring fewer humans to perform this basic task.
