1. How do the Internet standards allow for greater commerce?
means you can just go online and order something, instead of having to send an order via telegraph, heliograph, carrier pigeon and pony express and probably have the address translated 3 times.
Or back in 1985 or so I could send email, but it probably had to go through a couple of gateways between DECnet and Bitnet and Arpanet, and there weren't any attachments, or ways to represent any language other than English, and hardly any vendors had email anyway so you'd have to use telex, or fax, or paper documents.
