3

Features in Traditional programs that are not in an Expert system include

- sequential control structures
- distinct input/output variables
- passive data elements

4

In a large database system maintained on a mainframe computer, the most common medium for data files for the database is

hard disk

5

When implemented, the control ______ would best assist in meeting the control objective that a system have the capability to hold users accountable for functions performed

activity logging

6

The following task would be included in a document flowchart for processing cash receipts:

compare control and remittance totals

7

Routines that utilize the computer to check the validity and accuracy of transaction data during input are called

edit programs

8

Operating system is

a software program that controls the overall operation of a computer system

9

A compiler is

a computer program that converts a source program into an object program

10

Compatibility check/test is

a procedure for checking a password to determine if its user is authorized to initiate the type of transaction or inquiry he or she is attempting to initiate

11

A checkpoint/restart procedure is primarily designed to recover from

hardware failure

12

Internal checks are

- limit check
- identification
- sequence check
- error log
- transaction log
- arithmetic proof

13

Limit check is

a check to identify if data have a value higher or lower than a predetermined amount

14

Identification is

a check to determine if data is valid

15

Sequence check is

a check on the sequencing of info

16

Error log is

an up-to-date log of all identified errors

17

Transaction log is

a detailed record of every transaction entered in a system through data entry and provides the basic audit trail

18

Arithmetic proof is

a check to compute the calculation and validate the result

19

Characteristics of computer machine language include

- internal binary code
- hexadecimal code
- on/off electrical switches

20

Assembly language is

a programming language in which each machine language instruction is represented by mnemonic characters (symbolic language)

21

Many companies and government organizations would like to convert to open systems in order to

use less expensive computing equipment

22

In general, running open systems:

- increases # of available vendors
- decreases the average purchase from one vendor
- decreases volume discounts
- reduce economies of scale
- reduce reliance on proprietary components

23

The purpose of a software monitor is to

collect data on the use of various hardware components during a computer run

24

Specialized programs that are made available to users of computer system to perform routine and repetitive functions are referred to as

service "canned" programs

25

Relationship between source, object, and compiler programs

A source program "source code" is a computer program written in a source language which is translated into the object program by using a translation program like a compiler

26

A decision table indicates the

alternative logic conditions and actions to be taken in a program

27

Example of a decision table is

a chart that indicates shipping costs based on total purchase price

Purch. Ship
$ 1-$50 $4
$50-$100 $5
$101-$250 $7

28

An ERP system has the following advantages over multiple independent functional systems:

increased responsiveness and flexibility while aiding in the decision making process

29
