Question 6

Cloud computing is slower in allowing a user accesss to internal applications.

Question 7

Question 8

A turnkey system is a system that integrates individual, traditional business functions into a series of modules so that a single transaction occurs seamlessly within a single information system rather than several separate systems.

Question 9

A company may consider outsourcing if it feels that its core mission does not involve managing an information systems unit and that it might achieve more effective computing by turning over all of its operations to a more experienced, computer-oriented company.

Question 13

In many instances, off-the-shelf software can meet over 80 percent of an organization's needs.

Question 14

Referencing enterprise solutions, the difference between the modules and traditional approaches is that the modules are integrated to focus on the business functional areas, rather than on business processes.

Question 21

Reuse is the use of previously written software resources, especially objects and components, in new applications.

Question 22

Question 29

Reuse will not increase programmer productivity.

Question 30
