Answer Key

Cloud storage

Section A: Quick Questions

A — On remote servers that you reach over a network

B — Your files are stored on someone else's computers

A — Open it from your laptop by signing in to your account

A — A network connection, such as the internet

B — You cannot open the file until you reconnect

Section B: Match the Pairs

cloud storage → Keeping your files on remote servers that you reach over a network

upload("photo.jpg", cloud) → Sends a copy of a file over the network to be stored on a remote server

You can open your cloud files from many devices, like a phone and a laptop → open("photo.jpg", from=phone) open("photo.jpg", from=laptop)

Cloud storage needs a network connection to reach your files → if network == "offline": cannot_open(file)

cloud_files = stored_on(my_own_laptop) → Cloud files are not stored on your own laptop. They are stored on remote servers owned by another company.

open(cloud_file, network="none") → Cloud files cannot be opened with no network. A connection to the remote server is needed.

Section C: Definitions

cloud storage — Cloud storage keeps your files on remote servers, owned by another company, that you reach over a network. You can open them from many devices, but you need a connection.

Section D: Fill in the Blanks

cloud files are stored on a remote server

IF connected = true THEN open cloud file

devices = ["phone", "laptop", "tablet"]
FOR EACH device IN devices
    open cloud file

IF file is in the cloud THEN
    owned by another company

send photo over the network to the server
now stored in the cloud

Section E: Spot the Error

B — Uploading to cloud storage needs a network connection. The condition should be 'if connected:' so the upload only runs when the device is online.

C — The files are kept on the cloud's remote servers, not on the device. They should be fetched with cloud.download_all().

B — Cloud storage is on someone else's computers, owned by another company. The line should be owner = "another company".

D — The loop uploads each file to cloud storage, so the message should say the files are saved to the cloud, not on this device.

C — There is a missing comma between the two arguments. It should be open_cloud(d, "notes.txt") so each device can open the same cloud file.
