Static and Dynamic
Static!? - data is seperate, there is no link
"when you copy a file, e.g a spreadsheet and change the original ....
The Copy will NOT change!"
Dyanamic - data is linked
"when you copy a file, e.g a spreadsheet and change the original ....
The Copy WILL change!"
OCR!? - Optical Character Recognition
Hardware? - Scanner
Software? - OCR Software
This allows us to scan a hard copy of a file and it picks up the text (recognises text) and you can edit it!
Saves you re-typing!
