If I save a file in my google drive, I can access it on any device if I have an internet connection.

If I save a file on the desktop of the PCAD computers, I can access that same file if I log onto the computer next to it.

If I save a file on OneDrive using one of the PCAD computers, I can log on and find it on the computer next to it.

Apart from a device and a google account, what else do you need to access files in your google drive?

Do I need to sign in to save a file in OneDrive?
