W41-Information Systems within a Business Flashcards
Q1. A software package that is used with a large set of organized data that presents the computer as an expert on a particular topic is referred to as a(n)
a. Data mining
b. Expert system
c. Artificial intelligence
d. Virtual reality
Q1. (b) an expert system presents the computer as such an expert. Data mining uses tools which look for trends or anomalies without advance knowledge of the meaning of the data. Artificial intelligence is a branch of computer science that involves computer programs that can solve specific problems creatively. Virtual reality involves computer creation of an artificial, three-dimension world that may be interacted with.
Q2. Computer memory which is used to store programs hat must be accessed immediately by the central processing unit is
a. Primary storage
b. Secondary storage
c. Tertiary storage
d. Tape storage
Q2. (a) primary memory is quickly accessed and generally used to store programs that must be accessed immediately. Secondary storage has no meaning in information technology. Tape storage requires relatively long access times.
Q4. The part of the computer that does most of the data processing is referred to as the
a. Analyzer
b. Compiler
c. CPU
d. Printer
Q4. (c) the CPU, the central processing unit, does the primary processing for a computer. A compiler is used to compile a particular type of computer program. A printer is an output device.
Q5. An “office suite” of software is least likely to include a(n)
a. Database
b. Operating system
c. Spreadsheet
d. Word processing
Q5. (b) operating systems, (e.g., Windows, Linux, Unix) is not ordinarily included in an office suite.
Q6. Software that performs a variety of general technical computer-controlling operations is a(n)
a. Integrated “suite.”
b. Shareware
c. Database
d. Operating system
Q6. (d) an operating system controls the execution of computer programs and may provide various services
Q8. MIPS stands for
a. Memory in protocol standards
b. Millions of instructions per second
c. Mitigating individualistic personnel standards
d. Multiple input physical savings
Q8. (b) MIPS is an abbreviation for millions of instructions per second, a unit for measuring the execution speed of computers.
Q10. Which of the following characteristics distinguishes computer processing from manual processing?
a. Computer processing virtually eliminates the occurrence of computational error normally associated with manual processing
b. Errors or fraud in computer processing will be detected soon after their occurrences
c. The potential for systematic error is ordinarily greater in manual processing than in computerized processing
d. Most computer system are designed so that transaction trails useful for audit purposes do not exist
Q10. (a) the high degree of accuracy of computer computation virtually eliminates the occurrence of computational errors
Q12. The Systems Development Lift Cycle (SDLC) is the traditional methodology for developing information systems. In which phase of the SDLC would the activity of identifying the problem(s) that need to be solved most likely occur?
a. Analysis
b. Implementation
c. Planning
d. Development
Q12. (c) planning is the first phase of the SDLC and this information is needed before most of the analysis phase activities can be initiated.
Q13. Samco Inc. is in the process of designing a new customer relations system. In which phase of the development life-cycle would a needs assessment most likely be performed?
a. Analysis
b. Design
c. Development
d. Testing
Q13. (a) in the analysis phase the term attempts to get an understanding of the requirements of the system
