Answer Key

Advantages of cloud storage

Section A: Quick Questions

A — They can open the file from any device that has an internet connection

A — The user can easily pay for more storage space from the provider

B — The cloud storage provider

A — Files can be shared easily by sending a link or giving access

B — Users do not need to buy or maintain their own storage devices

Section B: Match the Pairs

Upload report.docx to cloud, open on phone → Access files from any device with an internet connection

Plan: 100 GB -> 1 TB → Storage space can be increased easily without buying new hardware

The provider looks after backups, so files are safe if the user's laptop breaks → backup = provider.copy(files)

Files can be shared with other people easily by sending them a link → share(file, link, friend)

Cloud storage works with no internet, anywhere → Cloud storage needs an internet connection to reach the data. It cannot be used offline, so this is not an advantage.

Cloud advantage: user buys and fixes servers → The provider owns and maintains the servers and storage hardware. The user does not have to buy or maintain them.

Section C: Definitions

cloud storage — Saving data on a provider's remote servers so you can reach files from any device online, add space easily, get backups done for you and share files, without buying your own hardware.

Section D: Fill in the Blanks

cloud.upload("notes.docx")

IF internet = TRUE THEN
  OPEN("notes.docx")
ENDIF

space ← 50
space ← space + 100

provider.backup(files)

cloud.share("notes.docx", "Sam")

Section E: Spot the Error

D — The closing bracket is missing. Any device with internet can open cloud files, and the call must end with ): open("cloud/notes.txt").

C — The comparison is the wrong way round. Extra space should be added when used storage is nearly at the limit, so it should be used > limit - 10.

C — A comma is missing between the two arguments. Easy file sharing needs share(files, friend).

A — With cloud storage the provider handles the backups, not the user. It should be backup_by = "provider".

A — A function definition must end with a colon. It should be def upload(file):.
