The Importance of Information Systems Management, 8e (McNurlin/Sprague/Bui)
Chapter 5 Distributed Systems: The Overall Architecture
1) An IT infrastructure is a blueprint that shows how a system will look.
2) An IT infrastructure is the implementation of an IT architecture.
3) The degree to which a system is distributed can be determined solely on the basis of how
processors and other devices are connected.
4) The OSI reference model is mature technology, having been in use with mainframe
environments since the 1970s.
5) Linux is an example of open source software.
6) SUMURU was designed to serve exclusively as a distributed e-mail system for multiple-user
systems.
7) Operating system standards define protocols for file transfers and e-mail.
8) The first distributed system structure was a hierarchy of processors.
9) Peer-to-peer architecture is the current trend in distributed networks.
10) Computer-to-computer use of the Internet is referred to as Web Services.
11) Currently, XML is the only Web Services software standard.
12) SOAP and UDDI are two of the most widely used Web Services communications standards.
13) Web Services refers to software modules that have their own URLs and can be called upon
to perform their function via the Internet.
14) Service-oriented architecture is designed to extract data from one system for use in another.
15) An SOA can be implemented by utilizing Web Protocols to achieve a loose coupling between
two or more distinct services.
16) The more complex a system is, the more important its architecture is to the interrelationships
among the system components.
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.
18) The Internet has become a global electronic infrastructure at the center of a worldwide
distributed system.
19) A distributed database is a database that is stored in one physical location
20) Opens systems is a reference to standardized interfaces that will allow applications to
interoperate across multivendor networks, operating systems, and databases.
21) Which of the following is a valid type of system interoperability?
A) a two-way flow of messages between user applications
