Info Systems 1004A

Define Information Systems, Their components and objectives
- Information Systems is a technology used to solve business problems. In
accordance with accounting, business etc.

- General Information System:
- Set of interrelated components that work together to achieve an objective
- structure: defined by its components (which can differ): an organised arrangement
of parts to create a unified whole
- behaviour: its work, what it does
- Input (raw data, biometrics, voice recognition) —> Processing —> temporary
storage —> Output (results: the useful information we need)—> feedback —>
permanent storage
- feedback must be relevant and its purpose is to maintain a balance
- react, make changes: system can be more effective in accomplishing its objective
- eg. Sakai
- Processing:
- delay between capture of data (input) and the physical process (eg write an exam,
wait for marking, release of results over a period of time)

- hence the need for a temporary storage space
- also get permanent storage space
- Move from permanent (what you buy) to temporary storage, when opening an
app while app is processing. Can process multiple apps (RAM speed depends on
how fast it can process)
- online storage space eg Google Drive
- Manual (components: data, people, technology, procedures eg rules/methods) vs
- Computerised: CBIS (computer based information systems): hardware, software,
databases, telecommunications, people, procedures — components, configured
to collect, manipulate, store, and process data into information — behaviour

- CBIS is a simplified manual IS (eg saves time, eliminates other actions required in
manual)
