Understanding Cloud Storage Concepts

The video tutorial provides an in-depth look at cloud storage, contrasting it with local storage. It explains the infrastructure of cloud storage, including data centers and servers, and discusses features like web-based and mobile interfaces. The tutorial covers synchronization, accessibility, and the advantages of cloud storage, such as scalability and automatic backups. It also addresses the disadvantages, including costs, security concerns, and data privacy issues.

What is the primary difference between cloud storage and local storage?

• Cloud storage is accessed via the internet, while local storage is stored on personal devices.

• Cloud storage is stored on personal devices, while local storage is on remote servers.

• Local storage is more secure than cloud storage.

• Local storage is accessed via the internet, while cloud storage is not.

Where are the files stored when using a service like OneDrive or iCloud?

• On a local server in the user's city

• In large data centers around the world

• On the user's personal computer

• Directly on the user's mobile device

Which of the following is NOT a way to access cloud storage?

• Mobile application

• Directly from a USB drive

• Web-based interface

• Desktop application

What is a key advantage of cloud storage in terms of accessibility?

• Files can be accessed only during business hours.

• Files are stored offline for better security.

• Files can be accessed from anywhere with an internet connection.

• Files are only accessible from the device they were uploaded from.

How does cloud storage offer scalability?

• By allowing users to physically add more hard drives

• By enabling users to easily adjust storage capacity online

• By requiring users to purchase new devices for more storage

• By limiting the amount of data that can be stored

How does cloud storage handle data backups?

• Users must manually back up their data.

• Backups are typically automatic and managed by the provider.

• Backups are not available in cloud storage.

• Users need to purchase additional software for backups.

What is version control in cloud storage?

• A feature that allows editing files only once

• A feature that saves multiple versions of a file for recovery

• A feature that deletes old versions of files automatically

• A feature that prevents file sharing

What is a potential disadvantage of relying on cloud storage?

• It is always free of cost.

• It guarantees data privacy in all countries.

• It requires a constant internet connection.

• It offers unlimited storage space.

Why might the cost of cloud storage be a concern for small users?

• The cost is a one-time payment.

• The cost is negligible for small users.

• The cost decreases with more storage usage.

• The cost is recurring and can add up over time.

What is a security concern associated with cloud storage?

• Users have full control over the security of their data.

• Users must trust the cloud provider's security measures.

• Cloud providers always guarantee data security.

• Data is always stored in the user's home country.
