 27. Cloud storage is evolving to fight hackers! A decentralized cloud provides more security to any individual or company’s data, as it is not controlled by a single entity. How does this help stop the manipulation/deletion of data?
storage_cloudstorage1.png

  All movements of data are tracked so it is impossible to manipulate or delete data without the user’s permission

  Cloud storage keeps data in 'high' shelves - out of the reach of hackers.

  Cloud storage keeps data in 'high' shelves - out of the reach of hackers.

  Data is kept under lockdown. No one, including the user, can access it easily.

 28. What is cloud computing?

  Storing our data online instead of on our own hard drive

  Storing RAM on an online server

  Downloading data to the clouds in the sky

  Storing our data offline instead of online

 29. What are the advantages of cloud computing?
1) You can access your files wherever you are if there
is an internet connection and a 
device that you can view and edit them on

2)It will provide you with a faster internet speed 

3)It may save money as there is no cost to maintain the 
storage i.e. Administration costs

  None

 30. What are the disadvantages of cloud computing?
1) The occasional downtime - You will not be able to access any of your 
applications, server or data from the cloud 

2) You can only control and manage the data and 
applications 

3) Data is vulnerable as cloud storage is a
public service

  TRUE

  FALSE

 32. What are the advantages of private cloud storage?
1) Efficiency and control as the private cloud storage is hosted either
 on site or a privately hosted environment 

2) High level of customisation (you can choose the infrastructure with specific 
storage and networking characteristics, so the system meets your individual 
needs perfectly) 


3) Has a greater level of security compared to public cloud 
storage as all data is saved and managed on servers in which 
no other company has access to
