Compare the telephone network and the Internet. What are the similarities? What
are the differences?

(looks like comp. sci. homework

similarities – both use cables or fibre, both allow end-to-end transmission of data
differences – telephone network uses dedicated circuits (while you are on the phone, there is a single link carrying sound from you to the far end). Internet uses data packets that are routed according to best path; there is no dedicated circuit and packets might take different paths and be reassembled later.

At least, that’s the stock answer from 1985. Nowadays a lot of phone traffic is VoIP (over the Internet), and there are dedicated light paths on the Internet, so it’s a bit blurred.
