What this dot point is asking
This outcome is about cloud storage and working together online. You should be able to explain what cloud storage is, how files save and sync across devices, how to share files with the right permissions, how several people can collaborate on one document, and the benefits and risks. In the written paper you explain cloud storage, collaboration and permissions, and weigh the advantages against the risks.
The answer
What cloud storage is
Cloud storage means saving your files on servers on the internet, run by a provider, instead of only on one computer. Because the files live online, you can reach them from any device that has internet access. A copy is usually kept on your device too, and the two are kept matching.
Saving and syncing
Syncing is keeping the same file up to date everywhere. When you save a change on one device, the cloud updates and the change appears on your other devices automatically. This means you can start work on one computer and continue on another, always seeing the latest version.
Sharing with permissions
You can share a cloud file with other people, and you control what they can do through permissions:
- Can edit. The person can change the file. Give this to people who should work on it.
- Can view. The person can read but not change it.
- Comment only. The person can add comments but not edit the content.
You can also share with named people rather than with anyone who has the link, which keeps the file private to the right people.
Online collaboration
Because a cloud document can be opened by more than one person at once, several people can edit the same file at the same time and see each other's changes live. This avoids the old problem of emailing different versions back and forth and trying to merge them by hand. Everyone works on one shared, up-to-date copy.
Benefits and risks
- Benefits. Access from anywhere, automatic backup off your device, easy sharing, and real-time collaboration.
- Risks. If your account is hacked or your password is weak, others could reach your files; you need internet access to get them; and over-sharing a link can expose a file to people who should not see it.
Examples in context
Example 1. A group project. Four students write a report together in a shared cloud document, each with edit permission. They all type at once and see live changes, so there is one up-to-date version instead of four emailed drafts to merge.
Example 2. Handing in homework securely. A student stores homework in the cloud and shares a "can view" link with only the teacher, so the teacher can read it but not change it, and no one else can open it. If the student's laptop breaks, the file is still safe in the cloud.
Try this
Cue. Explain what cloud storage is and one advantage of it. (Saving files on internet servers so you can reach them from any device; an advantage is access from anywhere or automatic backup off your device.)
Cue. Describe how online collaboration lets two people work on one report together. (The document lives in the cloud, so both open it at once and edit at the same time, seeing each other's changes live, avoiding emailed versions.)
Cue. State one risk of cloud storage and how to reduce it. (If the account is hacked your files are exposed; reduce the risk with a strong password and by sharing only with named people, not a public link.)

Original4 marksExplain what cloud storage is, and give two advantages and one risk of storing files in the cloud instead of only on one computer.Show worked answer →
Cloud storage means saving files on servers on the internet, run by a provider, so you can reach them from any device with internet access rather than only from one computer.
Two advantages, for example:
- You can access your files from anywhere on any device that has internet.
- Files are backed up off your device, so if your computer is lost or breaks, the files are safe; sharing and collaboration are also easy.
One risk, for example: if your account is hacked or you lose your password, someone could reach your files, so a strong password and care over what you share matter; you also need internet access to get your files.
What markers reward: cloud storage as files kept on internet servers reachable from anywhere, two genuine advantages, and a real risk such as account security or needing internet.
Original4 marksTwo students need to work on the same report at the same time. Explain how online collaboration lets them do this, and describe how sharing permissions keep the file safe.Show worked answer →
Online collaboration lets a document live in the cloud so more than one person can open and edit it at the same time, seeing each other's changes update live. This avoids emailing different versions back and forth and merging them by hand.
Sharing permissions control what each person can do. The owner can give "can edit" to those who should change the file and "can view" or "comment only" to others, and can share with named people rather than everyone, so the file is not changed or seen by people who should not have access.
What markers reward: real-time shared editing of one document, the problem it avoids (many emailed versions), and permissions such as edit versus view and sharing with chosen people to keep it safe.
