Ubuntu Cloud and Server?

[cblnchat]

Right now i only have a few questions about a "Cloud" and a "Server" namely...what are they? What does a Cloud do and how do i interact with it? Same with a Server...what does it do and how does it pertain to what i do everyday?
Im more interested in the server btw. From what ive read, in a home server its always connected to the computers on your network and always exchanging info? At least thats what i got from all the gibberish i was reading online. I would really appreciate it if someone put it in simple terms plz.

Thanks very much...this is probably a lot to cover.

Well, those are some "special" installs for some requirements:

Server:
Installs a minimal CLI (command line interface) with internet wich is more than enought to install a web server, mail server, ftp server, file sharing server and stuff like that. It uses barely no resources so you can spend all your CPU/RAM in running the services. It doesn't install a Graphical Enviroment, and it's not meant for "End User" but for a 24/7 server computer.

Cloud:
Mostly the same as a server install, but this focus on creating virtualized machines services, so you can "create" several server machines all running from inside only one physical machine. You could google for "virtualization" and "cloud computing" if you need more info.

Best regards

OK...sorry im not very computer savvy so im not sure what all that means.
But im not very interested in the Cloud. Im more interested in the Server.
What are its uses in a home...for a general computer user? Does it back up your files or somthing?
