AIN2601 - QUESTIONS - study guide 1
When does raw data become valuable? - question and answerWhen processed into
information and used for decision making.
What is the difference between data and information? - question and answerInformation
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? - question and
answerActivities
Data entry
Data processing
Output and storage of data and information
Making decisions
List the characteristics of quality data. - question and answerAccurate
Complete
Reliable
Verifiable
Define Source Document - question and answerThe first documented record of an
activity that took place.
Name two input methods. - question and answerbatch input
online input
Define batch input. - question and answersimilar source documents grouped together,
and entered in the CIS periodically (daily / weekly / monthly)
When is batch input suitable? - question and answerWhen 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? - question and answerIncreased productivity
, lower hardware cost
What is the disadvantage of batch input? - question and answerThe CIS is not up to
date with the latest data and information.
Define online input - question and answerdata being immediately captured into the CIS
at the point where the activity occurs
What is the advantage of online input? - question and answerThe data in the CIS is
always up to date.
What is the disadvantage of online input? - question and answerMore 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? - question and
answerclassifying data
performing calculations
sorting data
summarising data
transforming data
Give an example of the processing method 'classifying data'. - question and
answerCash sales vs credit sales
Give an example of the processing method 'performing calculations'. - question and
answerCalculating the cost per unit (cost / number of units)
Give an example of the processing method 'sorting data'. - question and
answerCustomer names in alphabetical order
Give an example of the processing method 'summarising data'. - question and
answerExtracting all the transactions for one specific supplier.
Give an example of the processing method 'transforming data'. - question and
answerData is converted into a graph
Name the two processing types. - question and answerBatch processing
real-time processing
Define batch processing - question and answerwhen the transaction files are updated to
the master files periodically (daily / weekly / monthy)
Define real-time processing - question and answerthe immediate update of the
transaction files to the master files as the transaction occurs
