The internet it like roads. You have big roads that connect different cities/states, medium-sized roads that connect parts of a city to big roads, and small roads that connect your house to medium roads.
Your ISP is a Tier 3 ISP. They connect you to a larger ISP (Tier 2) which will connect to a very large ISP (Tier 1). Tier 1 providers connect to one another, which is what gives all people access to all other computers on the internet.
Your ISP is how you get connected to the larger web. Its basically the road that runs by your house – you use that first to go anywhere that any road connects to.
