Just WTF is 'the cloud'...well it is a server that holds your and other peoples files, and can receive and send more of your and other peoples files, and is also connected by ethernet or some other magic wire or wirelessly (really fancy magic) to other servers that can do the same.
OK
So what is a network... well it some server thingy that holds your and other peoples files, and can send and receive more of your and other peoples files, and is also connected by ethernet or some some other magic wire or wirelessly (really fancy magic) to other servers that can do the same :-)
So..a really huge network is what makes up the interweb right, and 'the cloud' is also really a part of that humogously huge network that helps to make the interweb too.
Then why TF call it some new stupid fancy name?
...MARKETING
Next we are getting the DECENTRALIZED INTERWEB.....hot digitty dog.
