The Internet: a "nuts and bolts" view
- The Internet is a "network of networks" that interconnects multiple networks managed by different organizations through Internet Service Providers (ISPs).
- It consists of end systems (hosts) that run network applications, packet switches (routers and switches), and communication links (fiber, copper, radio, satellite).
Internet Components
- Hosts: end systems that run network applications at the Internet's "edge".
- Packet switches: forward packets using routers and switches.
- Communication links: fiber, copper, radio, and satellite connections.
- Networks: collections of devices, routers, and links managed by an organization.
Internet Standards
- Request for Comments (RFC): documents containing technical specifications and organizational notes for the Internet.
- Internet Engineering Task Force (IETF): develops and maintains Internet standards.
