2)
An IT infrastructure is the implementation of an IT architecture. T

3)
The degree to which a system is distributed can be determined solely on the basis of how processors and other devices are connected. F

4)
The OSI reference model is mature technology, having been in use with mainframe environments since the 1970s. F

5)
Linux is an example of open source software.
T

6)
SUMURU was designed to serve exclusively as a distributed e-mail system for multiple-user systems. F

7)
Operating system standards define protocols for file transfers and e-mail. F

8)

Currently, XML is the only Web Services software standard.
F

12)
SOAP and UDDI are two of the most widely used Web Services communications standards. F

Web Services refers to software modules that have their own URLs and can be called upon to perform their function via the Internet. T

14)
Service-oriented architecture is designed to extract data from one system for use in another. F

15)
An SOA can be implemented by utilizing Web Protocols to achieve a loose coupling between two or more distinct services. T

16)
The more complex a system is, the more important its architecture is to the interrelationships among the system components. T

17)
An IT architecture includes the processors, software, databases, electronic links, and data centers, as well as the standards that ensure that the components seamlessly work together. F (infrastructure)
