S1 ICT: File Management and Backup (Paper 2: intermediate)
This paper drills the three easily mixed pairs together: Save against Save As, sync against backup, and absolute against relative paths. Ask whether the copy is independent and the answer usually appears.
Direct answers For numerical questions, write the conversion step before the answer so the reasoning is visible when marked.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 1 536 MB. | 1.5 times 1 024 equals 1 536, and the factor from GB to MB is always 1 024. |
| 2 | An absolute path starts at the drive letter while a relative path starts at the current folder. | A relative path survives moving the whole folder, whereas an absolute path then points nowhere. |
| 3 | Because deleting the file on the computer deletes the cloud copy too. | Syncing keeps a mirror of one set of data while a backup keeps a separate copy, so the two serve different purposes. |
| 4 | 10 240 photos. | 30 times 1 024 gives 30 720 MB and dividing by 3 gives 10 240 photos. |
| 5 | It is an executable program and may carry a virus or malicious code. | Such a file runs instructions the moment it is opened, so it should come only from a trusted source. |
| 6 | It prevents overwriting older versions so any revision can be recovered later. | The version number gives the order and the date gives the timing, and writing both is clearest. |
| 7 | About 341.3 minutes, roughly 5 hours 41 minutes. | 500 times 1 024 gives 512 000 MB, dividing by 25 gives 20 480 seconds, and dividing by 60 gives 341.3 minutes. |
| 8 | Three, with about 6 GB left over. | 30 divided by 8 gives 3 with 6 left, which cannot hold a fourth copy, so only whole copies count. |
| 9 | 80 GB. | 20 times 4 gives 80, so multiply by the number of copies kept and plan the space in advance. |
| 10 | No, because one disk failure destroys both copies together. | A backup belongs on another medium or at another site; a copy on the same disk is only tidying up. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
Keep three pairs apart: Save versus Save As (overwrite versus a new file), syncing versus backup (deleted together versus a separate copy), and absolute versus relative paths (from the drive versus from the current folder).Tutor Registration →
