3. Input
Input refers to entering the data into the system.
Data can be entered by a variety of methods, for example:
- a keyboard to manually type in the data
- a mouse to select from a list of options
- scanning a barcode
- using an optical mark reader
- MICR
Examples of input data could include:
- data collected by a temperature sensor being automatically input into a central heating system
- student grades from a piece of homework being entered into a teacher's electronic markbook
- lottery ticket numbers being 'fed' into an OMR which then enters them into the National Lottery system
