The concept of cloud computing refers to the use of memory and storage and computation capabilities of computers and shared servers and networked through the Internet, following the principle of grid computing.
Data storage is done in facilities that can be accessed from anywhere in the world, anytime, with no need to install software or store data x. Access to programs, services and remote files is via the Internet – hence the allusion to the cloud. The use of this model (environment) is more feasible than the use of physical units.
In an operating system available on the Internet from any computer, anywhere, can access information, files and programs into a single system platform independent. The minimum requirement is a compatible computer with available resources on the Internet. The PC becomes just a chip connected to the Internet-the “great cloud” of computers is only required input devices (keyboard, mouse) and output (monitor).
