Chapter 2 An Introduction to System Concepts

1)From a systems perspective, how would you classify a computer operating system?

1. 1. A tangible system
   2. A physical system
   3. A conceptual system
   4. A perceptible system

2. Anything outside the system boundary represents the                                        that the system operates.
   1. interface
   2. subsystem
   3. environment
   4. super system

3. A large organization’s IT system might have specific programs such as marketing, manufacturing, purchasing, inventory, finance, and accounting. These are considered                                          to the larger IT system.
   1. interfaces
   2. subsystems
   3. the environment
   4. super systems

4. The division of a system or subsystem into its components and linkages is called
   1. itemization
   2. reconstruction
   3. decomposition
   4. categorization

5. What is not part of an abstract description of system architecture?
   1. system constraints
   2. system interconnections
   3. linkages among the components
   4. physical location of the servers

6. Which of the following are not input devices?
   1. stylus
   2. headphones
   3. touch screen
   4. mouse and keyboard

7. The system architecture representation of the flow and processing of data within an organization is called
   1. three-tier architecture
   2. application architecture
   3. flow control architecture
   4. customer oriented architecture

8. Scalability is the ability of a system to
   1. handle a growing amount of work.
   2. allow access to information when it is needed.
   3. protect data against unauthorized access or modification.
   4. allow configuration, monitoring, and maintaining operation.

9. Information availability is the ability of a system to
   1. handle a growing amount of work.
   2. allow access to information when it is needed.
   3. protect data against unauthorized access or modification.
   4. allow configuration, monitoring, and maintaining operation.

10. Data security is the ability of a system to

1. handle a growing amount of work.
2. allow access to information when it is needed.
3. protect data against unauthorized access or modification.
4. allow configuration, monitoring, and maintaining operation.

11. System administration is the ability of a system to

1. handle a growing amount of work.
2. allow access to information when it is needed.
3. protect data against unauthorized access or modification.
4. allow configuration, monitoring, and maintaining operation.

12. In a client-server architecture, the only limitations to running multiple applications on a single server are the potential slowdowns that may result from the load on the server computer and

1. traffic on the Internet.
2. load on client computer.
3. users who open many web browsers.
4. the traffic on the network to that server.

13. A two-tier architecture simply means that there are                            computers involved in the service.

1. one
2. two
3. two to five
4. two or more

14. A web-browser connected to a web-server is an example of

1. multiprocessing
2. cluster computing
3. n-tier architecture
4. client-server technology

15. Because response time is considered an important measure by most Web users, it is often more practical to separate the database and page processing into a third computer system. This is an example of

1. multiprocessing
2. cluster computing
3. n-tier architecture
4. three-tier architecture

16. The protocol that makes communication between a Web server and a database application possible is called

1. SQL
2. HTTP
3. Database Control Language
4. Common Gateway Interface

17.                                        is software designed to handle potential incompatibilities between the application software that resides on different equipment.

1. Middleware
2. Versioning software
3. Compatibility software
4. Application interface software

18. The organization's internal network, isbcommonly called a(n)

1. intranet
2. employee network
3. corporation network
4. organizational network

19. Internet standards such as                       allow the easy identification of relevant data within data streams between interconnected systems, making these applications possible and practical.

1. XML
2. FTP
3. SSH
4. HTTPS

20. What is not a benefit of cloud services?

1. Backup and offsite storage
2. Additional computing capability when and where it is needed
3. Lower hardware and software investments
4. Added security

Chapter 2 Discussion Questions

1. What is the top-down approach to system architecture?

2. What are the benefits of the top-down approach to system architecture?

3. Give a short description of peer-to-peer architecture.
