Using myself as an example, when I'm in the office, multiple gigabytes get transferred internally between servers and users, on the "corporate intranet."*
When at home, accessing the corporate network, all my interactions with the servers or other users must go over the (shared) Internet. *I know that's an old term, but there's no need to abandon it.
