|
|
What is repetitive processing?
|
Carrying out the same task to the same standard repeatedly (consistency), e.g. Processing the payroll run on a computer for a large organisations. Robots used in computer aided manufacturing.
|
|
|
What is speed of processing?
|
Carrying out many complex computer calculations in a relatively short time intervals, e.g. it would be impossible to produce accurate weather forecasts for the next five days without a powerful computer.
|
|
|
What is data storage capacity?
|
Able to store an enormous amount of information in a small space, e.g. all the information on pupils in a large school will fit on a hard drive compared to use numbers of filing cabinets.
|
|
|
What is speed of searching?
|
Able to find information quickly, e.g. a police check will find information on a particular car almost instantly.
|
|
|
What is accuracy and context?
|
Calculations are carried out accurately, e.g. in a spreadsheet if formula and data are correct then the calculations will be correct.
|
|
|
What is speed of data communications?
|
Messages sent out across the world instantaneously, e.g. an email can be sent from the UK to USA within seconds.
|
|
|
What is the ability to produce different output formats
|
Information can be produced in tabular or graphical format, e.g. a scientist producing a report will include data in a table and to make some of them easier to understand will produce some of them as graphs
|
|
|
What is ease of editing?
|
Text can be changed rather than being rewritten.
|
|
|
What are factors that might affect the efficiency of data processing systems?
|
- Hardware
- Software - Testing - Maintenance procedures - Change in circumstances - Speed of implementation - Poor communication |
|
|
How would Hardware affect the efficiency of data processing systems?
|
If a system has an old and slow processor then it will take longer to process data, it would also cost to upgrade.
|
|
|
How would Software affect the efficiency of data processing systems?
|
Does the software put a big demand on the system - does it work with other software. Will the system be compatible with old data.
|
|
|
How would Testing affect the efficiency of data processing systems?
|
Has the system been checking in all sorts of situations to see if it is reliable for example.
|
|
|
How would Maintenance procedures affect the efficiency of data processing systems?
|
Is there someone whose jobe is to ensure that the data and software are kept up top date. Proper backups in place?
|
|
|
How would a Change in circumstances during development affect the efficiency of data processing systems?
|
Have user requirments changed?
|
|
|
How would Speed of implementation affect the efficiency of data processing systems?
|
Has it been rushed through development?
|
|
|
How would Poor communication with the user affect the efficiency of data processing systems?
|
Results in poor understanding of user requirements
