Cloud computing – oversimplified..
instead of using only the resources on your personal computer, you leverage the resources of other computers & servers you can access over networks or internetworks.

Tools.. heck, thousands..
open source stuff like rsync (*nix backup) , commercial applications like Microsoft Live Cloud storage, Amazon Music Cloud storage/player, Google sites, Google apps, numerous online backup websites (Carbonite?), and even hosted applications like CitrixGoToMeeting, GoToMyPC, Microsoft Live Office, and Video streaming.

Advantages / disadvantages:
Pro: more storage & computing power without the cost to buy or overhead to maintain it.
easier to upgrade & add-on technology
external tech support to help
available even if your primary computer system(s) go down
Cons: net expenses are more than buying the equipment yourself.
information security can never really be guaranteed; you need to trust a 3rd party.
3rd party may live up to SLA (service -level -agreement) or not..
3rd party may fail backups, be destroyed by floods / fire..
3rd party may go bankrupt or get bought out.
latency.. the info / apps you use are not on your machine, so you have the network lag to deal with.
