how is the internet connected intercontinentally?
i know back in the day they laid huge cables down under the sea for telegraphs and morris code.
and wireless seems to be too much of a bottle neck to really be acceptable.
how do they wire up North America's networks to the networks in Europe and other continent thus forming the internet.

There are 3 kinds of ISP's (Internet Service Provider). There are the small ones like Comcast and AT&T that people like us connect to. These are called tier 3 or something. If you want to access a website and the server for that website is next door, it will stay within that same ISP. However, let's say you have Comcast and the website has AT&T, it will go from comcast to a bigger ISP called a tier 2 or whatever and then to AT&T and then finally to the server for the website. When you need to go even further, the tier 2 ISP's connect to a huge one called a tier 1, these are owned by big companies that you're probably not familiar with (at least I'm not) or some are government owned. They connect to each other directly, they actually have a cord connecting them.
