    Cloud computing basically means that the applications normally found in your computer, like microsoft word, excel (math spread sheet), etc. now resides in the cloud (a server on the internet). including all your files that you work on. You will hear the term SaaS which means Software as a Service.

    Whats the benefits....

    1. All your files are safe on-line and accessible from anywhere in the world you have internet access and a computer.

    2. You don't need to worry about buying new applications in your local computer because it will all be on line and costing much less than if you were paying for duplicate copies of the software in you local business.

    3. No need to worry about updating the software as well.

    4. You can arrange to have backups of all your important files on to a separate server clear across the country which is great in case of fire, earthquakes, etc.

    5. You have full control of access to the files.. via online management screens.

    6. If you have special programs that require large amounts of processing power, the service provider can provide this extra processing for additonal costs.

    7. No more paying for that expensive IT guy and taking care of larger servers in the network as your service provider is responsible for that and making sure their are spares, redundant servers, building power, network, etc...

    It would be interesting to know that in the beginning when there were no home size computers, corporation would have Main Frames and all the terminals were in the same room or building.

    Then came modems that allowed for the terminals to be in remote offices allowing the terminals to talk to a central mainframe via dedicated circuits like telephone lines.

    Then came the internet that was orginally knon as ARPA net and controlled by the federal government, used basically in text mode only for email and database applications. And now the main frames are located in the "Cloud" or Internet... making it less costly especailly to small business and non-profits.

    Hope this helps

    Cloud computing is a colloquial expression used to describe a variety of different computing concepts that involve a large number of computers that are connected through a real-time communication network (typically the Internet). Cloud computing is a jargon term without a commonly accepted non-ambiguous scientific or technical definition. In science, cloud computing is a synonym for distributed computing over a network and means the ability to run a program on many connected computers at the same time. The popularity of the term can be attributed to its use in marketing to sell hosted services in the sense of application service provisioning that run client server software on a remote location.

    Cloud computing is simply using the computer power of servers over the internet.

    For example, renting a server from amazon.com to hold a database for your business. That would be cloud computing.

    NOTE: cloud computer and cloud storage are NOT the same. Cloud computing actually uses the processors on remote servers while just storing stuff doesn't (well..not enough to matter)

    Cloud computing is bascially working on the web. All your stuff in stored on servers and you access them and work with them.

    There's Google Docs to work with letters, spreadsheets, presentations, etc. It's very much like Microsoft Office.

    There's Dropbox - where you can store any file in the "cloud".

    I don t use cloud for a simple reason, security. I don t what someone else to control or to have access to my personal information.

    Secure information? That is debatable, because if the server goes down, hacker or a glitch, then I can t get my own information.

    I prefer to have total control of my information then relinquish my control to someone else.

    Cloud computeing stores files and data on internet servers so that the files and such take less space on your internet friendly device.

    Source(s): this is my understanding.

    Storing your files on the internet server makes them vulnerable for hackers to steal, hold for ransom or just destroy. Your cloud service can increase fees if they so desire.
