LibreOfficehttp://www.libreoffice.org/download/

• A product from some folks who broke away from Open Office.

• Both Open Office and LibreOffice are available for Windows, Mac and Linux operating systems.

• While both have features like Conditional Formatting, Pivot Table and Solver, some Excel feature might be missing or work differently. Do not open critical Excel files in a free app.

Cloud computinghttp://en.wikipedia.org/wiki/Cloud_computing

Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility (like the electricity grid) over a network (typically the Internet).

Cloud computing entrusts, typically centralized, services with your data, software, and computation on a published application programming interface (API) over a network. It has a lot of overlap with software as a service (SaaS).
