What is a cloud?

Cloud usually refers to an online storage system.


  • Let us say you have created a document on your favourite text editor on your desktop computer.
  • Now you want to access that document from your mobile phone.
  • What you need is a common storage area which is accessible to both your computing devices, namely the desktop computer and the mobile phone.
  • Such a storage facility available on the web is called a cloud, also known as online storage.
  • After you have finished working on the document, login to your cloud storage provider application on the Internet and save your document there (assuming of course that you do have an account there).
  • Later when your desktop computer is out of reach and you need that document, just login again to your cloud storage from another computer or your mobile phone to access it.
