3.4D Network Providers and Services

Who provides the network

The internet has no single owner. You reach it through companies that own parts of it. A network provider builds, owns, or operates the infrastructure that carries data.
The provider most people deal with directly is the internet service provider (ISP), the company you pay for a connection at home or on your phone.
An ISP does more than open a door: it supplies equipment, assigns your connection an address, sets your speed, and often bundles extras (email, phone).
1. In return it can see, shape, and meter the traffic flowing through it.
This matters because the ISP sits between you and everything online. Its coverage decides whether you can connect at all, and its pricing and policies decide the cost and whether a service runs fast, throttled, or blocked. Different providers offer different coverage, prices, and policies, so which one is available to you affects whether and how you can get online.

From local ISP to global backbone

A single ISP cannot reach the whole world. Providers connect in a rough hierarchy: local ISP to regional providers to the huge networks carrying traffic between countries.
That long-distance core is the internet backbone. A request climbs from your home up through the chain, across the backbone, and back down to the network hosting the site.
Providers agree to pass each other's traffic, which stitches many separate networks into one internet.
