Interpretations of Moore's law assert that:

) computing power doubles every 18 months.

SaaS refers to:

. E) hosting and managing access to software applications delivered over the Internet to clients on a subscription basis.

All of the following are typically factors in a firm's decision to engage consulting and system integration services except:

E) The firm's staff knows more about the firm's IT infrastructure than service providers.

All of the following are cloud computing services except:

E) virtualization as a service.

IT infrastructure consists of only those physical computing devices and software required to operate the enterprise

False

Client/server computing is a primary example of decentralized processing.

True

Enterprise infrastructure requires software that can link disparate applications and enable data to flow freely among different parts of the business.

True

List and describe four services that comprise IT infrastructure, beyond physical devices and software applications.

• The service components of IT infrastructure include: • Telecommunications services that provide data, voice, and video connectivity. • Data management services to store, manage, and analyze data. • Application software services that provide enterprise-wide capabilities. • Physical facilities management services, to develop and manage physical installations of technology. • IT standards services that establish and monitor the firm's policies. • IT education services that provide training in use of the systems. • IT research and development services that research potential projects, products, and investments

Infrastructure-as-a-Service (IaaS):

A) is one type of cloud computing service where users pay only for the computing capacity they actually use.

Prewritten, commercially available sets of software programs that eliminate the need for a firm to write its own software programs for certain functions, are referred to as:

A) software packages.

Which of the following refers to the ability of a computer, product, or system to expand to serve a larger number of users without breaking down?

B) Scalability

Which of the following is the network standard for connecting desktop computers into local area networks that enabled the widespread adoption of client/server computing and local area networks and further stimulated the adoption of personal computers?

C) Ethernet

Which of the following enables a single physical resource (such as a server or a storage device) to appear to the user as multiple logical resources?

C) Virtualization

Firms that allow employees to use their own devices are embracing which of the following?

D) BYOD

Which type of software is created and updated by a worldwide community of programmers and available for free?

D) Open source

All of the following are current hardware platform trends except:

D) Unix.

The Windows Operating System

D) is an operating system used on most Wintel PCs throughout the world.

In green computing, reducing computer power consumption is not a top priority.

False

The operating system is used to manage the software applications used in business activities.

False

Distinguish between cloud computing, green computing, and quantum computing.

In cloud computing, technology services are provided over a network, primarily the Internet. These may be infrastructure services, such as storage or networking, or platform services, such as IBM's application development and test service, or software services, such as salesforce.com. Green computing refers to practices and technologies for designing computer equipment to minimize impact on the environment. Quantum computing refers to emerging technology that uses the principles of quantum physics to dramatically boost computer processing power.

What are the drawbacks of cloud computing? Do you think these ever outweigh the benefits, and if so, in what cases?

Students should be able to identify at least two drawbacks. Drawbacks include: 1. placing data storage and control in another firm's hands. 2. security risks in having critical systems and data entrusted to a firm that does business with other firms. 3. loss of business capability if cloud infrastructures malfunction. 4. dependence on cloud computing provider and switching costs. Student answers regarding the relative weight will vary, an example is: The disadvantages of cloud computing outweigh the advantages, except if any data lost is irreplaceable or creates harm to others. For example, a database of financial information should remain the responsibility of the original firm so that they can be held accountable.
