A personal cloud is a collection of digital content and services that are accessible from any device through the Internet. It is not a tangible entity, but a place that gives users the ability to store, synchronize, stream and share content on a relative core, moving from one platform, screen and location to another. Created on connected services and applications, it reflects and sets consumer expectations for how next-generation computing services will work.[1][citation needed]
The four primary types of personal cloud in use today are: Online cloud, NAS device cloud, server device cloud, and home-made clouds.
