Question 2

Which of the following is not one of three variations of Moore's Law,none of which Moore ever stated?
A) the power of microprocessors doubles every 18 months
B) computing power doubles every 18 months
C) computer size decreases every 18 months
D) the price of computing falls by half every 18 months

Accepted Answer

Moore's Law is a prediction made by Gordon Moore in 1965 that the number of transistors on a microchip would double every 18-24 months, leading to an exponential increase in computing power. The three variations commonly associated with Moore's Law are A, B, and D, as they all relate to the increase in computing power or performance. However, computer size decreasing over time is not directly related to Moore's Law, and therefore option C is not one of the variations of Moore's Law.

Question 3

Hardware and software acquisition costs account for about ________ percent of TCO.
A) 20
B) 40
C) 60
D) 80

Accepted Answer

While hardware and software acquisition costs are important in total cost of ownership (TCO), they typically only account for about 20% of the total cost. Other factors such as maintenance, support, training, and administration costs make up the majority of TCO.

Question 4

The practice of contracting custom software development to an outside firm is commonly referred to as
A) outsourcing.
B) scaling.
C) service-oriented architecture.
D) application integration.

Accepted Answer

The term commonly associated with contracting custom software development to an outside firm is outsourcing. Choice B , scaling, typically refers to the process of adjusting resources to accommodate changes in demand. Service-oriented architecture (SOA) is a design pattern for building software systems that allows different services to communicate with each other. Application integration refers to connecting different software applications to work together seamlessly.

Question 5

A set of self-contained services that communicate with each other to create a working software application is called
A) Web services.
B) EAI software.
C) SOA.
D) SOAP.

Accepted Answer

SOA (Service-Oriented Architecture) is a set of principles and methodologies for designing and developing software as a collection of interoperable services. These services are self-contained and communicate with each other through well-defined interfaces, allowing for greater flexibility, reusability, and agility in software development. Web services and SOAP are technologies that can be used to implement SOA, but they are not synonymous with it. EAI (Enterprise Application Integration) software is a broader category that includes technologies for integrating different applications and systems within an enterprise, but it is not the same as SOA.

Accepted Answer

Android is currently the most popular mobile operating system, accounting for approximately 85% of the global market share, followed by iOS with approximately 14%. Linux and Chrome OS, while used in some mobile devices, have a much smaller market share in comparison.

Question 8

Which model can be used to analyze the direct and indirect costs to help firms determine the actual cost of specific technology implementations?
A) total cost of ownership
B) return on investment
C) breakeven point
D) cost-benefit analysis

Accepted Answer

The total cost of ownership (TCO) model takes into account both direct and indirect costs associated with implementing a specific technology. This includes not only the initial cost of purchase or installation, but also ongoing costs such as maintenance, upgrades, and training. By analyzing the TCO, firms can determine the actual cost of the technology and make informed decisions about whether to invest in it.

Question 9

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?
A) modality
B) scalability
C) expandability
D) disintermediation

Accepted Answer

Scalability refers to the ability of a system to expand to handle a greater number of users or increased workload without breaking down. Modality refers to different modes of operation or communication available in a system, while expandability refers to the ability to add new features or components to a system. Disintermediation refers to the removal or reduction of intermediaries, such as middlemen or brokers, in a transaction or process.

Question 10

What is the foundation technology for Web services?
A) XML
B) HTML
C) SOAP
D) UDDI

Accepted Answer

XML (Extensible Markup Language) is the foundation technology for Web services. It provides a format for data exchange between different systems and allows for the standardization of data formats and structures. HTML, SOAP, and UDDI are all related to Web services, but they are not the foundation technology. HTML is a markup language used for creating web pages, SOAP is a protocol for exchanging messages between systems, and UDDI is a directory for storing and retrieving information about web services.
