I read a lot about the lunar landing but not much about how they cam back. What was the launching vehicle like? Rockets leaving earth look huge. Ones leaving moon may probably be 6 times smaller. That's still big. Landing vehicle has that much fuel? Must have been risky landing in such fuel laden craft.

How about the local loop in my computer? If I am using the lo interface to run a program, am I 'tax'nically on a LAN?
