it's a server that (for example) you can keep all you photos on. You save them in "the cloud" and you don't have to take up storage space on your own device. Then when you need to access/look at them, you can download them onto whichever device you are using. Again an example, but if i save my music on my amazon cloud, i can download them onto my kindle, my tablet, phone or laptop depending on where i am when i want to listen. You do need wifi to download though
personally i would never put any important files on the "cloud" to many breaches of security in everything nowadays,photos etc ok so long as not dodgy ones
If you use web based email such as hotmail or gmail then you are already using the cloud and can access your emails from any device connected to the internet.
I store all of my photos, videos, movies, ebooks, music in the cloud and many of my files and documents.
thats ok HC nothing i have in any e-mail would be any problem for me.
i dont have any passwords i will store anywhere except in a notebook in my home that's the kind of items i am talking about. and btw if you say what if someone breaks into your home, well its like fort knox and passwords would be the least of my worries if anyone did
If anybody has a lot of stuff, like documents or photos that they need to save, then use a portable hard drive. I have a Toshiba 2 terrabyte one, that cost less than £50, and it works perfectly.
The main disadvantage of using an on-line storage facility, or "cloud" as it is called, is you need to be able to access the 'net to use it. What if you are not able to get access to the 'net ?
I use my portable HD in all sorts of places. Its only the size of a cigarette pack.
I've got the portable hard drive and the NAS, mikey, which automatically backs up everything from all my devices as I go.
The cloud is an extra back up for me, useful if I need to access anything from somebody else's device when I'm out and about. If everything fries in a fire it's still there, in the cloud, waiting to be download to new devices.
The first cloud storage I used, and still use, is Photobucket, long before 'the cloud' was a thing. Been using it years without a problem.
