This observation is known as Law.A) MurphysB) MooresC) AmdahfsD) MetcalfesAnswer: BAACSB: Information TechnologyDifficulty: 1: EasyCourse LO: Describe the major types of computer hardware and software used by companies.Learning Obj: LO 1.1: Why is introduction to MIS the most important class in the business school?Classification: ConceptWhich of the following statements is true of Moores Law?A) It is based on the technological advancements in weapon manufacturing.B) It made the cost of data processing, communications, and storage essentially zero.C) It states that the total number of transistors produced in the world doubles every 18 months.D) It has made the use of transistors obsolete.Answer: BAACSB: Information TechnologyDifficulty: 2: ModerateCourse LO: Describe the major types of computer hardware and software used by companies.Learning Obj: LO 1.1: Why is introduction to MIS the most important class in the business school?Classification: ConceptWhich of the following is a result of Moores law?A) The risk of technology becoming obsolete has decreased.B) The price to performance ratio of computers has fallen dramatically.C) The outsourcing of nonroutine skills has increased drastically.D) The cost of data processing has increased considerably.Answer: BAACSB: Information TechnologyDifficulty: 2: ModerateCourse LO: Explain how IS can be used to gain and sustain competitive advantage.Learning Obj: LO 1.1: Why is introduction to MIS the most important class in the business school?Classification: Concept33) What is abstract reasoning?Answer: Abstract reasoning is the ability to make and manipulate models. Constructing a model from the five components of an information system is an example of abstract reasoning. AACSB: Information Technology Difficulty: 1: EasyCourse LO: Describe the components of an information system (IS).Learning Obj: LO 1.2: How will MIS affect me?Classification: ConceptWhat is systems thinking?Answer: Systems thinking is the ability to model the components of a system, to connect the inputs and outputs among those components into a sensible whole that reflects the structure and dynamics of the phenomenon observed. It shows how components* inputs and outputs relate to one another.AACSB: Information TechnologyDifficulty: 1: EasyCourse LO: Describe the components of an information system (IS).Learning Obj: LO 1.2: How will MIS affect me?Classification: ConceptWhat is collaboration? How can one ensure effective collaboration?Answer: Collaboration is the activity of two or more people working together to achieve a common goal, result, or work product. It means to develop ideas and plans with others in a team and to provide and receive critical feedback. Effective collaboration is not about being nice. Surveys indicate the single most important skill for effective collaboration is to give and receive critical feedback.AACSB: Information TechnologyDifficulty: 1: EasyCourse LO: Describe the components of an information system (IS).Learning Obj: LO 1.2: How w川 MIS affect me?Classification: ConceptWhat is experimentation? Explain its importance.Answer: Experimentation is making a reasoned analysis of an opportunity, envisioning potential solutions, evaluating those possibilities, and developing the most promising ones, consistent with the resources one has. Fear of failure paralyzes many good people and many good ideas. This can be overcome by having the ability to experiment.AACSB: Information TechnologyDifficulty: 2: ModerateCourse LO: Describe the components of an information system (IS).Learning Obj: LO 1.2: How will MIS affect me?Classification: ConceptDifficulty: 1: EasyCourse LO: Discuss best practices for using and managing databases.Learning Obj: LO 5.1: Why do you need to know about databases?Classification: ConceptThe purpose of a database is to.A) test and troubleshoot newly installed softwaredesign the source code for computer programsB) describe and build computer architecturesstore lists of data involving multiple themesAnswer: DAACSB: Information TechnologyDifficulty: 1: EasyCourse LO: Discuss best practices for using and managing databases.Learning Obj: LO 5.1: Why do you need to know about databases?Classification: Concept3) Google is a database that is used by Facebook and Twitter.Answer: FALSEAACSB: Information TechnologyDifficulty: 1: EasyCourse LO: Discuss best practices for using and managing databases.Learning Obj: LO 5.1: Why do you need to know about databases?Classification: ConceptDatabases are static and it is only the information systems that change.Answer: FALSEAACSB: Information TechnologyDifficulty: 1: EasyCourse LO: Discuss best practices for using and managing databases.Learning Obj: LO 5.1:
