WHAT responsibility is normally reserved for a Systems Programmer in a computer system environment?
Operating Systems and Compilers
WHY? - Because systems programmers are given responsibility for maintaining system software
i.e. Operating systems and Compilers
WHAT is an input control that could prevent an incorrect abbreviation from being accepted as legitimate data?
A Validity Check
WHY? - Because a Validity check tests the identification numbers or transaction codes for validity by comparison with items already known to be correct or authorized
WHAT is a likely concern in performing an assessment of an electronic data interchange (EDI) purchasing system?
THE increased turnover of the IT Staff
WHY? - Because changes in personnel suggest that crucial expertise may have been lost
WHAT control procedure is effective in ensuring that data files uploaded from a personal computer to a server are complete?
And that no additional data was added?
Batch control totals, including control totals and hash totals
WHY? - Because Batch control totals for the data transferred can be reconciled with the batch control totals in the existing file
WHAT does a combinatorial test design do?
IT identifies the number of tests needed to get the coverage developers want
WHAT is a “Database?”
A Collection of Related Files
NOTE: The use of a database system significantly reduces redundancy of stored data in a system
WHAT Database Model is considered “most versatile?”
A Relational Database
WHY? - Because the data is organized into two-dimensional tables (relations), which makes this database model easier to construct compared to more complex models
Also, the tables can be combined (joined) in many ways to permit a wide variety of inquiries.
Fill in the Blank.
eXtensible Markup Language (XML) allows the user to design A tags.
A. customized
i.e. XML is focused on the content of the data and is useful for putting structured data into a text file
WHAT type of computer language is C++ BASIC, FORTRAN, and COBOL?
Procedural Languages
i.e. They are considered “higher-level” languages which allow specification of processing steps in terms of highly aggregated operations
WHAT is the greatest advantage of a database (server) architecture?
Data redundancy can be reduced
WHAT is “Cooperative Processing?”
A System that permits computers in a distributed network to share the use of another end user’s application program
An economic Feasibility analysis model can be embedded as a subsystem of what type of information system?
A Decision Support System (DSS)
WHY? - Because it is an interactive system that is useful in solving semi-structured and unstructured problems
i.e. It requires that a top-management or middle-management decision maker to exercise judgment

focuses on strategic (long-range) objectives and gives immediate information about a firm’s critical success factors
BI is NOT a program for providing top management with advice and answers from a knowledge-based (expert) system.
True or False
Devices used only to perform sequential file processing will not allow data to be edited on a real-time basis
TRUE
Devices used only to perform sequential file processing will NOT allow data to be edited on a real-time basis
WHY? - Because in an online, real-time system, “direct” (random), NOT sequential, access to files are required
WHAT is NOT considered advantage in an Distributed computing system?
Security Measures………THEY are NOT easier to provide
WHY? - Because Security becomes more difficult when there are more sites to secure
