Dropbox

Dropbox is a widely popular and essential tool which allows users to store their files (documents, photos, etc) on the "cloud" to access them from any internet device (computer, tablet, smartphone). It functions like a folder on your desktop where you can organize and create any sub-folders you want, but files are not saved on any hard drive: instead they are saved on Dropbox's servers and synced automatically every time you make any change, thus ensuring that your files are accessible from any device at any time: no need to email files to yourself! Students should never tell you any more that they've "lost the homework because of a computer crash".
Box

Box is very similar to Dropbox: you can also save, sync and access your files from any internet device (computer, tablet, smartphone) without having to save anything on a hard drive or having to email files to yourself.
Google Docs

Google Docs is the highly popular Google application which allows users to share and edit collectively documents (text, spreadsheets, etc). The "owner" of the document can decide whether to give only "viewing" permission to other collaborators, or actually give them "editiing" privileges which then allow all collaborators to edit the document together. Changes are automatically synced and saved on Google's server and Google Docs are accessible from any internet device (computer, tablet, smartphone).
ConceptBoard

ConceptBoard is a more elaborate version of Google Documents: this simple tools allows users to share documents, edit them collectively. But contrary to Google Docs, you can actually scribble notes on the document the same way you would with a pencil and instantly share the notes you've added with all other users who are viewing the document. You can even use this tool to mark papers entirely online.
iCloud

iCloud is a functionality of Apple's operating systems which works on MacBooks, iPads or iPhones: document files (text, tables, photos, music, contacts, etc) are automatically saved on Apple's servers (the "cloud"), synced, and accessible from any of your Apple internet devices. You can also access your iCloud files from any non-Apple computer (including PC) by simply going to www.iCloud.com and logging into your account.
