Question 3: Differentiate between relative and absolute hyperlinks.
Answer: Hyperlinks can be used in Calc to jump to a different location from within a spreadsheet. Hyperlinks can be stored within your file as either relative or absolute.
An absolute link will stop working only if the target is moved. A relative link will stop working only if the start and target locations change relative to each other. For instance, if you have two spreadsheets in the same folder linked to each other and you move the entire folder to a new location, a relative hyperlink will not break.
