AP CSP Day 17: Internet Structure
Share
The internet is a network of networks connected through routers that forward data packets toward their destinations. No single entity controls the entire internet; its decentralized structure makes it resilient and scalable. AP CSP exam questions about internet structure test whether students understand how path redundancy allows data to be rerouted around failures. The concepts of bandwidth, latency, and the role of Internet Service Providers are also part of the Big Idea 4 content students need to master.

How the Internet Is Structured
A Network of Networks
The internet is not a single network but millions of interconnected networks. Home networks connect to Internet Service Providers. ISPs connect to regional networks. Regional networks connect to high-capacity backbone networks. Routers at each junction forward packets toward their destination.
Decentralization
No single organization owns or controls the entire internet. This decentralization means the internet can continue functioning even when large sections fail or are taken offline, because traffic can route around the damaged portions.
Practice Question
Which of the following best describes the structure of the Internet?
The Internet is a decentralized network of networks. Millions of smaller networks (ISPs, universities, companies) interconnect using standardized protocols like TCP/IP to enable global communication.
A) The Internet has no single central point — it is decentralized by design. C) Websites are hosted on millions of different servers worldwide, not one. D) The Internet relies heavily on physical infrastructure including fiber optic cables, routers, and data centers.
Students sometimes think the Internet is centrally controlled or that it exists only as wireless signals. The physical infrastructure of cables and routers is essential.
The Internet is decentralized and uses open protocols. No single organization owns or controls it. This design provides resilience and scalability.
