This diagram shows three main parts: Device A where the user saves a file, the Cloud Storage that holds the file online, and Device B which receives the synced file. Arrows show data moving through the internet.

Flowchart Quiz - 3 Questions

What happens if Device A is not connected to the internet when saving a file?

A The file stays only on Device A until internet is available.

B The file is immediately uploaded to the cloud.

C Device B downloads the file directly from Device A.

D The file is deleted automatically.

Key Result

Cloud storage and sync work by uploading files from one device to the internet and then updating other devices automatically when they are online.

Practice

1. What is the main benefit of using cloud storage?

easy

A. Files are deleted after 24 hours automatically.

B. Files are only saved on your computer's hard drive.

C. You can access your files from any device with internet.

D. You must manually copy files to each device.

Solution

   Cloud storage saves files online, not just on one device.

2. Step 2: Identify the main benefit

   This means you can open your files from any device with internet access.

3. Final Answer:

   You can access your files from any device with internet. -> Option C

4. Quick Check:

   Cloud storage = Access anywhere [OK]

Hint: Cloud storage means files live online, not just locally [OK]

Common Mistakes:

• Thinking files stay only on one device
• Confusing sync with manual copying
• Believing files auto-delete quickly

2. Which of these is the correct way to describe file syncing?

easy

A. Automatically updating files on all devices.

B. Manually copying files between devices.

C. Deleting files from the cloud after use.
