QUESTIONS AND ANSWERS
DISTINCTION GUARANTEED
When does raw data become valuable? - ANS-When processed into information and used for decision
making.
What is the difference between data and information? - ANS-Information is data that have been
processed into something meaningful that can be used in decision making.
What are the steps in the computerised information system process? - ANS-Activities
Data entry
Data processing
Output and storage of data and information
Making decisions
List the characteristics of quality data. - ANS-Accurate
Complete
Reliable
Verifiable
Define Source Document - ANS-The first documented record of an activity that took place.
Name two input methods. - ANS-batch input
online input
, Define batch input. - ANS-similar source documents grouped together, and entered in the CIS
periodically (daily / weekly / monthly)
When is batch input suitable? - ANS-When a huge number of similar source documents must be
captured;
When up-to-date data and information are only required on the same frequency as the frequency of
data capturing.
What is the advantage of batch input? - ANS-Increased productivity
lower hardware cost
What is the disadvantage of batch input? - ANS-The CIS is not up to date with the latest data and
information.
Define online input - ANS-data being immediately captured into the CIS at the point where the activity
occurs
What is the advantage of online input? - ANS-The data in the CIS is always up to date.
What is the disadvantage of online input? - ANS-More costly than batch as hardware is required to
capture the data at each point where the activity to be captured takes place.
What methods can be used to process data into information? - ANS-classifying data
performing calculations
sorting data
summarising data
transforming data
Give an example of the processing method 'classifying data'. - ANS-Cash sales vs credit sales
