ONLINE STORAGE (CLOUD STORAGE)
We can also store data on various online platforms that allow online
storage, file sharing and syncing. It allows us to store data in an off-site
location which can be accessed later on any computer anywhere through
the Internet. If we store data in cloud storage, we can save money that Onedrive
would otherwise have to be invested in paying for storage devices.
