The Cloud is a term referencing storage of digital info/files on the internet. Normally your files are saved directly to your computer or phone. When this fills, one would say ‘I’m out of storage/space’. Often, one would now upgrade devices or delete info.
The Cloud, enables one to keep current device and buy storage at a company who dedicates servers for internet accessible uploading of others’ files, and often offers protection of your data (kind of like a storage facility would allow you a locked space for a fee).
Added bonus is you’d now have access to this data from any device which connects to the internet and can access tour account on this website.
Choices are endless. Google, your cell provider/manufacturer (i.e Apple iCloud), your virus protection, and thousand more. They are called the Host, as they host your data on their servers. The servers are web connected, you connect via login and have your info anytime anywhere, and no need to ‘burn’ it to a dvd or thumb drive
