What is OneDrive?
OneDrive for Business is Microsoft's answer to Dropbox and Google Drive. At its core, it's an online storage service that offers the ability to sync data automatically with one or more devices (desktop or mobile), and even edit documents stored on it (a la Google Docs). Overly-simplified, it's a hard drive in the cloud, and a very big one, at that.
If you're familiar with the concept of DropBox, you're familiar with the concept of OneDrive for Business.
OneDrive for Business drives the file sharing aspect to Office 365 Groups, too—it's the OneDrive "app" on your computer that will synchronize folders shared over to you (either from an Office 365 Group, or from someone sharing a personal OneDrive over to you) with your computer.
Every user has their own OneDrive, as does every Office 365 Group.
What does OneDrive do?
OneDrive for Business enables you to share information/documents with colleagues, no matter where they may be: across your building, or across the globe.
For example, you could maintain a set of Excel spreadsheets in a folder that synchronizes between your computer and a set of colleague's computers. When you or one of your collaborators makes any changes to one or more of the shared documents, those changes are replicated to everybody else's computers. On top of that, the collaborators have the ability to—at any time—access those files via their mobile device while they're on the go.
No longer are your documents "trapped" on your computer, or on the company file server.
