35) What are the implications of cloud computing for e-commerce?
Answer: Cloud computing has many significant implications for e-commerce. For e-commerce firms, cloud computing radically reduces the cost of building and operating websites because the necessary hardware infrastructure and software can be licensed as a service from cloud service providers at a fraction of the cost of purchasing these services as products. This means firms can adopt "pay-as-you-go" and "pay-as-you-grow" strategies when building out their websites. For instance, according to Amazon, hundreds of thousands of customers use Amazon Web Services. For individuals, cloud computing means you no longer need a powerful laptop or desktop computer to engage in e-commerce or other activities. Instead, you can use much less-expensive tablet computers or smartphones that cost far less. For corporations, cloud computing means that a significant part of hardware and software costs (infrastructure costs) can be reduced because firms can obtain these services online for a fraction of the cost of owning, and they don't have to hire an IT staff to support the infrastructure.

36) Explain each of the three important concepts behind the Federal Networking Council's definition of the term Internet. Explain how each technology contributes to the functioning of the Internet today.
Answer: The three important concepts in the Federal Networking Council's definition of the Internet are packet switching, the TCP/IP communications protocol, and client/server computing.
Packet switching is a method of slicing digital messages up into parcels that are sent along different communications paths as they become available. The packets travel from router computer to router computer and are then reassembled at their destination point. These routers are special purpose computers that interconnect the thousands of computer networks that make up the Internet. Since this method does not require a dedicated circuit, it makes use of any available spare capacity on any one of several hundred circuits enabling nearly full use of available communication lines and capacity.
Transmission Control Protocol/Internet Protocol (TCP/IP) is the universally agreed upon method for breaking the messages up, routing them to their destination, and reassembling them. The TCP protocol, or set of rules, specifies how messages should be formatted, ordered, compressed, and error-checked. It also stipulates which method the network will use to indicate that they have stopped sending and/or receiving messages and sometimes specifies the transmission speed as well. The IP protocol provides the addressing scheme for the Internet. Each computer connected to the Internet must be assigned an Internet Protocol address so that it can send and receive TCP packets. At present, each time home users sign on to the Internet they are temporarily assigned an IP address by their ISP.
Client/server computing involves very powerful personal computers connected in a network along with one or more server computers. These client computers can display rich graphics, store large files, and process graphic and sound files. The server computers are specifically allocated to common functions that all client computers need such as storing files and supplying software applications, and utility programs.

52) Identify and describe the two types of ISP service, along with the Internet connection methods, in use today.
Answer: There are two types of ISP service: narrowband and broadband. Narrowband service is the traditional telephone modem connection now operating at 56.6 Kbps (although the actual throughput hovers around 30 Kbps due to line noise that causes extensive resending of packets). This used to be the most common form of connection worldwide but has been replaced by broadband connections in most of the United States, Europe, and Asia.
Broadband service is based on DSL, cable modem, telephone (T1 and T3 lines), and satellite technologies. Broadband — in the context of Internet service — refers to any communication technology that permits clients to play streaming audio and video files at acceptable speeds — generally anything above .5 Mbps.
Digital Subscriber Line (DSL) service is a telephone technology for delivering high-speed access to the Internet through ordinary telephone lines found in a home or business. Cable Internet refers to a cable television technology that provides digital access to the Internet using the same analog or digital video cable providing television signals to a home. T1 and T3 are international telephone standards for digital communication. These are leased, dedicated, guaranteed lines suitable for corporations, government agencies, and businesses such as ISPs requiring high-speed guaranteed service levels. Additionally, some satellite companies offer high-speed broadband Internet access primarily to homes and offices located in rural areas where DSL or cable Internet access is not available. Access speeds and monthly costs are comparable to DSL and cable.

65) Describe and discuss 5G.
Answer: 5G is a new cellular standard being developed for high-bandwidth mobile broadband. Although official standards are not expected to be fully rolled out for a few years, 5G is expected to provide for speeds reaching 10 Gbps or more, support for up to 100,000 connections per square kilometer (known as massive machine-to-machine (M2M) connections), and ultra-low latency (less than 10 milliseconds) communications. Full deployment of 5G is expected to take several years, utilizing a new part of the wireless spectrum (shorter millimeter waves in the 30 GHz to 300 GHz range), and including the development of a transmission infrastructure. This proposed infrastructure will utilize tens of thousands of small cell and distributed antenna systems installed on utility poles, as well as additional investments in fiber optic networks. Telecommunications companies are expected to invest up to $5 billion. The first pre-official 5G devices launched in 2018, with more being deployed by 2019.

66) What are some of the issues related to the Internet of Things (IoT)?
Answer: Interoperability remains a major concern with IoT. As with many technologies in the early stages of development, many organizations are fighting to create the standards that participants in the market will follow. The AllSeen Alliance, formed by Qualcomm in 2013 with 50 other companies, including Microsoft and Cisco, was one group that hoped to create an open source standard. Membership in the Alliance soared after its initial founding and by 2016, it had over 200 members. Another group, the Open Interconnect Consortium, formed in 2014 by Intel, Broadcom, Dell, and others apparently not happy with the AllSeen effort, also reached over 200 members. In late 2016, these two groups put their differences aside and merged to create the Open Connectivity Foundation.
A different group, the Industrial Internet Consortium, was formed by AT&T, Cisco, GE, IBM, and Intel to focus on engineering standards for industrial assets. As with many other types of Internet-related technology, Google with its Android operating system and Apple with AirPlay wireless streaming protocol may be trying to create their own standards. Other concerns include security and privacy. Security experts believe that IoT devices could potentially be a security disaster, with the potential for malware being spread through a connected network, and difficulty in issuing patches to devices, leaving them vulnerable. Data from standalone smart devices can reveal much personal detail about a consumer's life, and if those devices are all ultimately interconnected, there will be little that is truly private.

74) Briefly describe the development of the Web including the key players.
Answer: The Web was invented between 1989 and 1991 when Dr. Tim Berners-Lee and his associates at CERN Laboratories built on the ideas of several earlier researchers and developed the initial versions of HTML, HTTP, a web server, and a web browser, the four essential components of the Web. Information being shared on the Web remained text-based until Marc Andreessen and others at NCSA (National Center for Supercomputing Applications) created a web browser with a graphical user interface. This made it possible to view documents on the Web that included colored backgrounds, images, and primitive animations. In 1994 Andreessen and Jim Clark founded Netscape, which created the first commercial browser. In 1995 Microsoft released the first version of Internet Explorer and the Web began to take off.

80) Why is VoIP considered to be a disruptive technology?
Answer: In the past, voice and fax were the exclusive provenance of the regulated telephone networks. With the convergence of the Internet and telephone, however, this dominance is already starting to change, with local and long-distance telephone providers and cable companies becoming ISPs, and ISPs getting into the phone market. Key players in the VoIP market include independent service providers such as VoIP pioneers Vonage and Skype (now owned by Microsoft), as well as traditional players such as telephone and cable companies that have moved aggressively into the market.

81) Explain how the Internet and the Web make e-commerce possible. Briefly discuss at least four features or services that support e-commerce.
Answer: The Internet and the Web have made e-commerce possible because they have brought about an extraordinary expansion of digital services to millions of amateur computer users. The Web makes nearly all elements of rich human expression including color, text, images, photos, animations, sound, and video available, creating a unique environment in which to establish a commercial marketplace. Many of the Web's services and features support e-commerce, including communication tools such as e-mail and messaging applications, search engines and streaming media.
E-mail, for example, can be used as a very effective marketing tool. E-commerce sites can buy e-mail lists from various sources and collate them with lists of their current customers to create a targeted advertising message that can be quickly and economically delivered and will produce a creditable response.
Messaging applications such as mobile messaging apps are increasingly being used by companies to market their brands.
Search engines have also become a crucial tool on e-commerce sites, providing a method for customers to quickly locate the product category or a specific product they are looking for.
Streaming media enables online video, music, video, and other large-bandwidth files to be sent to users in a variety of ways that enable the user to play back the files. Web advertisers increasingly use video to attract viewers. Streaming audio and video segments used in online ads and news stories are perhaps the most frequently used streaming services.
