Chapter 1 Computers and Systems

1)The architecture of the computer system rests on a solid foundation that has changed only slightly and gradually since the      .

1. 1. late 1930s
   2. late 1940s
   3. late 1950s
   4. late 1960s

 

2. The work performed by an individual computer system within the IT system can be characterized by
   1. hardware and software
   2. input, storage and output
   3. storage processing and output
   4. input, processing, and output.

 

3. As a matter of necessity, network interfaces must conform to standard agreements, known as                                                                                                                                                                                                                            ,

for messages to be understood by both computers during a message exchange between a pair of computers.

1. 1. protocols
   2. I/O services
   3. device controllers
   4. Ethernet standards

 

4. The components of an individual computer system consist of processing hardware, input devices, output devices, storage devices,
   1. and application programs.
   2. and operating system software.
   3. application software and operating system software.
   4. application software, file storage, and data processing.

 

5. The                                      provides the physical mechanisms to input and output data, to manipulate and process data, and to electronically control the various input, output, and storage components.
   1. data
   2. network
   3. computer hardware
   4. computer software

 

6. What is the only requirement for data to be manipulated and processed by a computer?
   1. The data type must be numeric.
   2. The data must be represented in binary form.
   3. The data type must be alphanumeric, graphic, sound or color.
   4. The size of the data must be smaller than the capacity of the hard drive.

 

7. Which of the following is not part of the conceptual view of a CPU?
   1. ALU
   2. Control Unit
   3. Interface Unit
   4. Main memory

 

8. The main memory, often known as primary storage, working storage, or RAM (for random access memory), holds
   1. data.
   2. program instructions.
   3. program instructions and data.
   4. program instructions, data, and instructions for booting the computer.

 

9. The idea that the program instructions and data are both stored in memory while being processed is known as the
   1. processing concept.
   2. stored program concept.
   3. data-instruction concept.
   4. memory-data-instruction concept.

 

10. Many of the internal OS services are provided by the                                      module, which contains the most important operating system processing functions.

1. CPU
2. root
3. kernel
4. central

 

11. The operating system's                                                                     acts as an interface for application programs and utilities to access the internal services provided by the operating system.

1. monitoring system
2. supervising system
3. application subsystem
4. application program interface

 

12. When the computer is started, a bootstrap or IPL (Initial Program Load) begins testing the system. Where is this bootstrap program stored?

1. RAM
2. ROM
3. hard drive
4. virtual memory

 

13. The fact that different types of computers can work together, share files, and communicate successfully is known as

1. supercomputing
2. open computing
3. distributed computing
4. coupled systems computing

 

14. The word, "virtual," as used in the text, is most synonymous with which word?

1. logical
2. notional
3. tangible
4. theoretical

 

15.                                are agreements among interested parties, often manufacturers, to assure that various system components will work together interchangeably.

1. Manuals
2. Standards
3. References
4. Operating procedures

 

16. Unicode is a(n)

1. character encoding standard
2. video encoding standard
3. audio encoding standard
4. graphic encoding standard

 

17. MPEG-4 is a(n)

1. text standard
2. video standard
3. audio standard
4. graphic standard

 

18. MP3 is a(n)

1. text standard
2. video standard
3. audio standard
4. graphic standard

 

19. Which of the following is not a feature defined in a protocol specification for communication?

1. message format
2. data representation
3. Operating System vendor
4. identification and authentication

 

20. Storage devices communicate with a computer using protocols. One such protocol is:

1. SATA
2. PATA
3. serial encoded messages (SEM)
4. hard-disk parallel communications protocol (HDPC) Chapter 1 Discussion Questions
   1. What do the following computing devices have in common: workplace computers, tablets, smartphones, and

computers embedded in other equipment?

 

 

1. 2. List five specific skills or abilities required of an information technology (IT) systems architect or system analyst?

 

Here is an example:

1. 1. 1. Design and implement systems that meet an organization's information technology (IT) needs.

 

 

3. The work performed by an individual computer system within the IT system can be characterized by the Input-Process-Output (IPO) model. Use the IPO model to analyze the process of purchasing a soft drink from a vending machine. Keep it simple!

 

 

4. On your home or school computer, find the CPU speed (in GHz), main memory size (in GB), and the size of the hard drive (in GB). Also find the operating system and its version.

 

 

5. Pick one of the protocols listed below and report on its origin, purpose and supporting organization. Recommend between 250 and 300 words. When using the Internet for research purposes, be sure to give the Author (if available), date of article (if available), name or title of the webpage, URL and the date accessed.
